Uma sikhuluma ngezinto ezisetshenziswayo ze-matte nokuthi zifakwa kanjani umthunzi, singena endaweni lapho kuhlangana khona izinjini ze-3D, abanikezeli, abahleli bezinto ezibonakalayo kanye nokugeleza komsebenzi wobuciko be-2D. Umgomo ovamile ukulawula ukukhanya ngaphandle kokuthi okokusebenza kucwebezele kakhulu noma kukhanye.ukugcina izithunzi ezikholakalayo kanye nokufunda okuhlanzekile kwevolumu.
Le ndatshana ihlanganisa futhi ihlele kabusha, ngendlela engokoqobo, ulwazi oluvela ezindaweni ezahlukahlukene (i-Unreal Engine, Blender, V-Ray, Rhino kanye namasu omdwebo wedijithali) ukuze ukwazi kahle ukulungiswa kwe-shading ezintweni ze-matte Ngaphandle kokulahleka phakathi kwamaphaneli namapharamitha. Uzobona imiqondo engokomzimba, amaqhinga okufiphaza, ukulungiselelwa okuthile, nezimo zezinkinga ezivamile, ezihlale zinezixazululo ezingokoqobo zokugeleza komsebenzi kwesimanjemanje.
Imiqondo eyinhloko: iyini "matte" nokuthi iphendula kanjani ekukhanyeni
I-matte material ithathwa njengenekhwalithi encane noma engenakho nhlobo; ubuntu bayo bulele ekusakazweni kwayo: Imunca ingxenye ye-spectrum futhi ibonise okunye kabanzi.Ezingeni lokubukwayo, libonisa umbala wento "owakhe" onokugqamisa okuncane nezithunzi ezichaza umumo ngaphandle kokuphazamiseka.
Isisekelo somzimba okufanele sigcinwe umehluko phakathi sabalalisa futhi ukucabangisisa okukhethekileUkukhanya okusabalalisayo kusabalalisa amandla okukhanya ezindaweni eziningi (ushoki, iphepha, ukhonkolo), kuyilapho ukukhanya okukhethekile kugxilisa ukubonakaliswa ku-lobe ngokujwayelekile. Ezimpahleni ze-matte, isakhi esisabalalisayo sihamba phambili, nakuba cishe zonke izinto zangempela zigcina ukukhanya okuthile.
Ukuze ulawule ingxenye esabalele ezinjinini nabahleli, kukhona amamodeli e-shading afana ne-Lambert, i-Oren-Nayar noma izinhlobonhlobo ze-Toon. I-Lambert iyindlela elula ye-classicalU-Oren-Nayar wengeza "i-roughness microscopic" kuma-matte angokoqobo; I-Toon icacisa izindawo ezikhanyayo nezimnyama ezinoshintsho olubushelelezi oluthe xaxa noma oluncane, luwusizo uma ufuna ukwenza isitayela.
Engxenyeni ecacile, uma umgomo uwukugcina ukubukeka kwe-matte, kuhle ukunciphisa, ukuthambisa noma ukuyivala. Amamodeli e-Phong, Cook-Torrance, Blinn, WardIso noma i-Toon Zilawula ubukhulu, ubulukhuni kanye nokuma kokukhanya; kuma-mattes, angaba buthuntu, noma ashiywe enobunzima obuphansi nombala ongathathi hlangothi.
I-Blender: Amaphaneli namapharamitha we-matte elawulwayo
I-Blender ibeka phakathi izinto ezibalulekile ezinkinobho zokufiphaza ngamathebhu amancane azinikele. Ukubuka kuqala kukusiza ukuthi ubone ngeso lengqondo umphumela wokugcina. Khetha okwakudala, vumela ukunqanda ukujwayela ekubukeni kuqala uma kudingeka futhi uhlole ukuthi umbala usabela kanjani lapho ushintsha izilayidi eziyisisekelo futhi ubone khulula izinhlelo zokuhlinzeka nge-3D.
Kokuthi "Izixhumanisi Namapayipi" udala futhi uphathe izinto zokusebenza: ungasebenzisa kabusha, uphindaphinde, noma "ususe ukuxhumanisa" izithenjwa. Inkinobho enezinombolo ikhombisa ukuthi zingaki izinto ezabelana ngezinto kanye ne U-X ususa isabeloImoto iqamba idivayisi ngokuzenzakalelayo, futhi u-F uphoqa "umsebenzisi oyisipoki" ukuze okokusebenza kungasuswa uma kungekho muntu oyisebenzisayo.
Ipayipi lihlanganisa ama-toggles abalulekile: I-Halo (iguqula ama-vertices abe ama-halos), i-ZTransp (ukukhanya ngaphandle kokulandelela i-ray, ngokushesha kodwa hhayi ngokomzimba), i-OSA egcwele (i-anti-aliasing egcwele), Intambo (imodi yocingo), Umsakazo (owuhlanganisa ku-radiosity), i-Cast kuphela (ithunzi lamaphrojekthi kuphela), I-Traceable (ibambe iqhaza ekulandeleleni i-ray-ray (i-Shadbufcounts) kanye namamephu we-Shadbufs). Kuma-matte "ahlanzekile", i-Cast kuphela neShadow/TraShadow enganquma ekwakhekeni..
Ama-halos akuvumela ukuthi ulingise ukukhanya okufana nelensi: uma i-Halo icushiwe, ukulungiswa kosayizi, ubulukhuni, izithasiselo kanye nezingxenye ezifana nemigqa, izindandatho noma izinkanyezi. Ama-halos awavamile ukusetshenziselwa izinto ezivamile ze-matte.Kodwa ukuzazi kuvimbela izimanga uma wenza kusebenze okusethiwe.
Ithebhu yokubalulekile iqukethe okubalulekile: umbala oyisisekelo, obala, nokunikezwa okuyisisekelo. Kunamathuluzi okukopisha nokunamathisela izakhiwo phakathi kwezinto nezinkinobho zokuziphatha njenge-Shadeless (akukho ukukhanya noma izithunzi, umbala oyisicaba). Uma ufuna i-matte "ethola" izithunzi, i-Shadeless kufanele ivalwe..
I-Blender ichaza imibala emithathu: Col (diffuse), Spe (specular), kanye ne-Mir (i-specular reflection). Ungawalungisa nge-RGB noma i-HSV; I-Alpha ibusa ukukhanya. Ukuze uqedele i-matte, indlela ejwayelekile iwukuthi I-Spe ephansi noma engathathi hlangothi kanye ne-Mir emhlophe uma ungafuni ukuboniswa, nakuba nge-PBR uzoyilungisa nge-Roughness ne-Metallic.
Emathunzini ahlukene, i-Lambert iyashesha futhi izinzile; U-Oren-Nayar wengeza ubuhwaba nge-Rough; I-Toon inikeza imiphetho echaziwe (Usayizi Nobushelelezi). Kumatte angokoqobo, I-Oren-Nayar ivamise ukuhlinzeka ngezindleko ezengeziwe ezintweni ezifana nokhonkolo noma indwangu.Ekuqedeni okukhethekile, i-Phong, i-CookTorr, i-Blinn, i-Toon, ne-WardIso ilawula ukwakheka nokuqina kokukhanya; ngesiphetho se-matte, nciphisa noma uvale umphumela okhethekile ukuze "ungaphuli" ukubukeka.
Ezinye izilawuli eziwusizo kakhulu: Ithunzi (thola izithunzi), i-TraShadow (izithunzi ezinokukhanyela), I-OnlyShadow (ibonisa kuphela izithunzi, igolide lokuhlanganisa) kanye ne-Emit (iphuma embala ohlukanisiwe). I-OnlyShadow iyinhlangano yakudala yokumboza i-CG ngemuva kwangempela ngaphandle kokubonakala kwejometri.
Ku-“Mirror Transp”, izibonisi ziqoqwa ngokulandela umsebe nokubonisa ngale: uma usebenzisa i-Ray Mirror noma i-Ray Transp, ilawula inkomba yokubonisa kanye ne-Alpha. Ukubonakala komzimba kuhlanganisa i-IOR (inkomba ye-refractive): 1.0 ngokungabi nakuphikiswa, 1.33 kwamanzi, kanye ~1.5 ngengilazi. Ku-matte ehlanzekile awudingi ukuphikiswaKodwa uma wenza ingilazi ye-matte efriziwe, khona-ke uzoba nesithakazelo.
Ipharamitha yokujula ikhawulela ukugxuma kwe-ray ukuze ibonakale/ikhanye: iphezulu, ibiza kakhulu. I-Fresnel ne-Fac zilinganisa ukuthi umphumela ukhuphuka kangakanani ema-engeli amadlelo; Isicwebezelisi sifiphalisa ukubonakala/ukukhanya, futhi amasampuli alungisa umsindo. Uma ukhuphula i-Gloss ngaphansi kuka-1.0 uzothola ukuboniswa kwe-matte okwengeziwe, ngezindleko zesikhathi sokunikeza.
I-SSS (I-Subsurface Scattering) ilingisa ukukhanya okuhlungayo futhi kugxume phezulu (isikhumba, imabula, ubisi). Kudinga izithunzi eziqondile; kuma-organic mattes, kungaba ukhiye wokugwema "i-plasticity." Yenze isebenze uma ufuna ivolumu ethambile enesikhumba noma i-wax., ngokusethwa kusengaphambili okuwusizo futhi ulungise izikali ngokucophelela.
Ithiphu yokumodela: Uma wenza ingilazi noma izinto eziqinile ezibonisa ngale, sebenzisa i-geometry evaliwe. Izindiza "ezingapheli" ezisetshenziselwa ukulingisa amakristalu aphula ukuphikiswa futhi kubukeka sengathi yonke into engemuva kwayo iyingilazi; ngefasitela, i-cube enezikali enogqinsi ingcono.
I-Unreal Engine: izinto “ezingakhanyi” ezamukela izithunzi
Ku-UE4/UE5, kuvamile ukudala into ethi "matte" ngomthombo wokukhanya oEmissive kuphela oxhunywe ukubukeka kohlobo lwe-Toon noma izinto ngaphandle kokukhanyisa okuqondile. Inselele ivela uma ufuna leyo nto ithola izithunzi ezicatshangelwayo ngaphandle kokwenza kusebenze ukukhanya okusabalalisiwe kohlobo lwe-Lambert okungonakalisa isitayela.
Kunezindlela eziningana ezisebenzayo. Okuqondile kakhulu ukubala igama lesithunzi bese uliphindaphinda ku-Emissive, njengokungathi "ungqimba lwesithunzi phezu kombala." Lokhu kufinyelelwa ngokuthwebula isici sethunzi ngamanodi esehlakalo noma ukwakheka. futhi uyilungise ngokusekelwe ku-albedo oyithola ku-Emissive. Kuyafana nobuqili obusetshenziswa ku-photogrammetry: ukubeka kakhulu imaski ebumnyama kuyilapho uhlonipha ingemuva.
Uma ipayipi lakho liyi-Toon, ungakwazi ukuhlanganisa ama-threshold alula nesithunzi semaski ukuze ugcine imiphetho ebukhali. Gwema ukujova ukukhanya okujwayelekile kokusabalalisa futhi esikhundleni salokho, isebenza kusizinda se-post-shading sento ngokwayoukuphoqa ukuphindaphindeka kwethunzi kokuthi Emissive. Kwamanye amaphrojekthi, Imisebenzi Yokukhanya noma i-shadow pass ekhethekile isetshenziselwa ukondla izinto ezingakhanyi.
Inothi elihambelanayo: Amanye amaphrojekthi agcinwa ezinguqulweni ezindala (isb., 4.15) ngenxa yezinguquko zenodi (kube nezimo zokuziphatha okungajwayelekile nge-OneMinus ku-4.17). Uma uthola ama-artifact ochungechungeni lwe-nodeQinisekisa umphumela wakho enguqulweni lapho wazi khona ukuthi ipayipi le-Toon lisebenza khona futhi uthuthe usebenzisa ukuhlola kwe-A/B.
I-V-Ray: I-Matte/Shadow enemephu yombala nezizinda
"Indiza ebamba ithunzi" yakudala yokuhlanganisa nengemuva idinga i-VRayMtlWrapper elungiswe kahle (noma i-matte material efanayo); ukuze uthole imininingwane yangemva kokukhiqizwa, bheka izithunzi zobungcweti ekunikezeniInkinga eqhubekayo ukuthi Ngomugqa wombala wemephu yonke into ifanelana ndawonye, kodwa ngokubonakala kwemephu okumpunga kuvela ama-halos ampunga.Indiza iyanyamalala noma ingemuva liyambala uma uvula izinketho ezifana nengemuva le-Affect on/off.
Amathiphu asebenzayo okwenza i-matte isebenze nge-exponential: Sebenzisa i-VRayMtlWrapper ene-Matte evuliwe, "Izithunzi" zivuliwe, futhi "Affect alpha" uma ufuna izithunzi ziphile esiteshini se-alpha. Cabangela “Ithonya ingemuva” kuphela uma ufuna ngempela ingemuva lithola ukuncipha kwethunziUma ufuna ingemuva elingaphazamiseki, likhubaze futhi uthwebule isithunzi nge-alpha noma ngento enikeza isithunzi.
Ukudweba okucacile kucindezela ububanzi obuguquguqukayo futhi kuphakamise "unyawo" lwesithunzi, bese kuba mpunga obisi. Ukunciphisa lokhu, zama “Ungathinti imibala (ukuzivumelanisa nezimo kuphela)” Kumephu Yombala, lungisa ileveli yesithunzi se-wrapper futhi ulinganise ukuchayeka kukonke. Uma isibhamu sishiya uhlaka olumpunga, hlola ukuthi isisekelo saso asiwengezi umbala (ukusethe kokungathathi hlangothi) bese ulungisa okuthi "Thola i-GI/Generate GI" ngokwenhloso yakho ukuze isibhamu singangcolisi noma siveze isithombe ngokweqile.
Uma ulungisa amapharamitha endiza Kusistimu futhi ubona uphawu olufanayo, ngokuvamile kuwuphawu lokungqubuzana phakathi kokuhlelwa kombala nesisonga se-matte. Hlukanisa futhi unqobe: khubaza i-GI, hlola ukudlula kwesithunzi, qinisekisa i-alphaUmzila oqinile uwukuhlukanisa amaphasi: ubuhle ngaphandle kweshothi kanye nethunzi endaweni ehlukile, bese uqamba ekukhiqizeni ngemuva.
I-Rhino: izinto ze-matte, i-PBR kanye nokwenziwa kwephaneli
Ku-Rhino, iphaneli Yezinto Zokusebenza ilawula umbala, ukuphela, ukukhanyela, indlela yokwenza, nokukhululeka kwalokho okunikezwa injini eyakhelwe ngaphakathi. Okuqukethwe (izinto ezisetshenziswayo, indawo ezungezile, kanye nendlela yokwenza) kungafihlwa kusetshenziswa ama-plugin noma imibhalo futhi kulawulwa ku... Imitapo yolwazi ongayihudula phakathi kwamaseshini.
Ibha yamathuluzi yephaneli ikuvumela ukuthi udale izinto ezintsha: kusukela kwekhona, inhlanganisela, into yangokwezifiso, into ezinhlangothi ezimbili, into ekhishwayo, igugu, ingilazi, insimbi, upende, i-PBR, isithombe, ukhonkolo, ipulasitiki, noma kusukela kuhlobo lwesiphequluli. Kunomsebenzi wokusesha ngegama, amanothi namathegi, imenyu yamathuluzi, nosizo. Izithonjana zibonisa izinkomba (isetshenziswe ekukhethweni, isetshenziswe ngaphandle kokukhethwa, ukuntuleka kwesithombe sangaphandle, njll.).
Izenzo ezivamile ezithonjaneni: imenyu yokuqukethwe ngokuchofoza kwesokudla, hudula ukuze uhlele kabusha, kopisha ngo-Ctrl, ireferensi ngo-Alt, chofoza kabili ukuze uhlele okuntantayo. Ukufakwa ngakunye kunegama elihlelekayo. kanye nezinketho ngokusho kohlobo.
Ingxube Yezinto Ezibalulekile: Iqukethe okungaphansi okubili okuhlanganiswe Ubuningi Bengxube. Ungangeza/ususe, wenze kusebenze/uvale i-submaterial ngayinye futhi Hlola ifolda ukuthola izinhlobo ezintshaIwusizo ekushintsheni okubushelelezi phakathi kwezingqimba (isb., upende + powder).
Okubalulekile Kwangokwezifiso (okumhlophe okuzenzakalelayo, okumatte, okungabonakali noma ukukhanya): umbala ohlukanisiwe, isiphetho esicwebezelayo (kusuka ku-matte ukuya kokucwebezelayo), ukukhanya, ukukhanya kanye ne-IOR uma kukhona obala. Kufaka phakathi ithebula le-IOR elijwayelekile (okungenalutho okungu-1.0, umoya 1.00029, iqhwa ~1.309, amanzi 1.33, ingilazi ~1.52–1.8, isimaragidu 1.57, irubi/isafire 1.77, idayimane 2.417).
Ukwakheka: umbala, obala, ukukhululeka/okuvamile, nendawo. Amafomethi asekelwayo: ngaphandle kokubonisa ngale (i-JPEG/JFIF, BMP) futhi ebonisa ngale (DDS, HDR/HDRi, EXR, PNG, TIF/TIFF, TGA). Ungavula/uvale ukuthungwa futhi ulungise inani lakhona ngokungena okuqondile noma ukuhudula.
Kumodi yokukhululeka/evamile, ukwakheka kwengeza imininingwane ngaphandle kokushintsha i-mesh. Kumodi yemvelo, sebenzisa izithombe eziyindilinga (imephu ye-engeli noma i-probe yokukhanya) ukuze uthole ukuboniswa okukholekayo; okunye ukuqagela kuyahlanekezela. Kuthuthukile: ukuzikhanyisela (kusabalalisa izithunzi nomthunzi), ukukhanya kwe-Fresnel, ukukhanya kwe-alpha (i-bitmap), ukupholisha okukhanyayo, ukucaca okusobala, nombala wokuphuma.
Izinhlangothi ezimbili: ivumela ukwaba izinto ezihlukene ebusweni bangaphambili nangemuva bezinto ezingenakho ukujiya (ubuso, amameshi amancane). Isebenza kakhulu emashidini, izindwangu ezincane, noma amaphosta.
Ukukhishwa: into eguqula into ibe umthombo wokukhanya (umbala onohlu lwe-Kelvin namandla). Iwusizo kwizikrini noma izibani ze-neon ngokulawula okuhle.
Amagugu: ukukhethwa kwamatshe ngama-presets; "Ingilazi": umbala, ukucaca kanye ne-IOR; "Insimbi": umbala, ipholishi kanye nezinye izinto ezilinganiselwe zokuthungwa; “Upende”: hlukanisa umbala futhi ucwebezele (okulungisa iFresnel nepholishi). Abalingisi I-matte, ayibonisi, ayithuki, futhi iyalungiseka ngombala. "Ipulasitiki" ivumela umbala, ukukhanya, ukupholisha, ukukhanya, ukucaca, nokukhululeka okulula.
I-PBR: ihlanganisa izindlela zomzimba zibe into eyodwa. Umbala oyisisekelo, ubulukhuni (kusuka kokucijile kuye kokusabalalisa), ukufiphala, nezinketho zemininingwane ukuze unike amandla/ukhubaze imithunzi. Ungangeza ukuthungwa kwe-PBR futhi uwabeke emseleni ngamunye; ubushelelezi bulawula ukushelela kwento (khumbula ukuguqula amamephu uma umphumela ukudinga). Kukhona futhi inkomba ye-refractive, i-refractive roughness, i-alpha (ukubonakala), kanye nesiphindaphindi sokukhanya.
Okubalulekile "Isithombe": igama, isithombe se-bitmap (inketho ye-grayscale), hlola, susa ukuthungwa, obala (sebenzisa imaski ye-alpha noma yombala). URhino akakusebenzisi ukubonisa ngale nge-JPEG/PCX/BMPKhetha amafomethi aneshaneli ye-alpha ukuze unqampune okuhlanzekile.
Ukuphatha nemiyalo: gcina/yabelana emitapo yolwazi; izinketho zomugqa womyalo ukubonisa iphaneli, ukwengeza, ukususa, ukuqamba kabusha, ukushintsha, ukuphinda, ukulayisha/ukugcina efayelini kanye yabela izinto noma izendlalelo (futhi ngokuphindaphindiwe kumabhulokhi). Kunezinketho ezithuthukisiwe zokuxazulula ukungqubuzana kwamagama phakathi kwamamodeli anamathiselwe/angenisiwe.
Umfanekiso we-2D: "Ungacabanga kanjani izibalo" ekuthungeni kwakho
Emdwebeni wedijithali, izinto ze-matte zakhiwa ngezendlalelo nezindlela zokuhlanganisa ezilingisa okomzimba: okusabalalisa okubusayo, okuthulisiwe okukhethekile, kanye izithunzi ezichaza umumo ngaphandle kokukhanyaUkugeleza komsebenzi okuvamile kuqala ngobuciko bomugqa, imibala eyisisekelo kusendlalelo, kanye nengemuva elimpunga elimaphakathi (kuphumuza amehlo futhi kusiza ekuhlolweni kombala). Xhumana no-a isiqondiso sokudweba imigqa namajamo.
Ukuze ubeke izithunzi, cabanga nge-3D noma upenda nge-2D: define umthombo wokukhanya ngaphambi kokufiphazaYenza ama-miniatures ngokuzama ngalokhu: ukukhanya okungaphezulu (ngaphandle emini bebade), ukukhanya okungaphambili (okungathathi hlangothi nokungajwayelekile), ukukhanya okusemaceleni (uhhafu wobuso ethunzini), ukukhanya okuphezulu (umkhathi oshaqisayo), ukukhanya kwe-backlight (epic), ukukhanya kwe-diagonal/oku-angle (okwemvelo nokuguquguqukayo).
Izendlalelo zethunzi zivame ukusethwa kokuthi Phindaphinda futhi zisikwe emibaleni eyisisekelo. Ngebhulashi elithungwe, ungakha imiphetho ecijile bese uwacwenga ngebhulashi elithambile. okuhlukahluka ngobulukhuni kuye ngebanga nosayizi womthombo. Ikhiya amaphikseli abonisa ngale ukuze ifake umbala ethunzini ngaphandle kokulahlekelwa imaski.
Umbala wethunzi: ngaphezu komthetho olula "ukukhanya okufudumele, isithunzi esipholile", cabanga ngokuqhathanisa: Uma ukukhanya kufudumele, isithunzi sizobanda kunezindawo ezikhanyisiwe.Futhi ngokuphambene. Uma kunelanga eliphuzi, umbala oluhlaza okwesibhakabhaka osuphelile emthunzini usebenza kahle kakhulu.
Izithunzi ze-Cast: Ngaphezu kokumnyama, engeza izithunzi eziveziwe phakathi kwezinto (izinwele ezisebusweni, ikhanda ehlombe). Ungakha isithunzi somzimba ngokuphindaphinda futhi ululaze ubuciko bomugqa nesisekelo, ukukhiya obala, ukugcwalisa ngokungathathi hlangothi nokusebenzisa i-Gaussian; voila, imaski esheshayo ezothengisa ukuthintana nomhlabathi noma imvelo.
Ukukhanya okuzungezile nokuvala: indawo ezungezile igcwalisa izithunzi ngombala (isibhakabhaka, izindonga, izinto eziseduze). Empeleni, ungakwazi ukwengeza isendlalelo ngaphezu kwethunzi ngokufiphala okuphansi kumodi evamile futhi upende "okuluhlaza okwesibhakabhaka," noma ukwenze kusendlalelo esifanayo sokuphindaphinda ngombala oluhlaza okwesibhakabhaka nebhulashi lomoya. Izindawo ezivalekile azikutholi ukukhanya kwelanga noma umoya we-ambient futhi ayoba amnyama kakhulu (amafolda avaliwe, izikhala ngaphansi kokugqagqana).
Ukuhlakazeka komhlaba kanye nokopha okuncane: Ekukhanyeni okuqinile, imiphetho yethunzi ingagcwala ukukhanya okungenayo nokuhlunga (isikhumba esibomvu, izindwangu ezinhle). Penda lokhu "kopha" ngebhulashi eliqinile ukuze uthole imiphetho kanye nebhulashi elithambile ukuze uthole amaphuzu avelele abanzi. kodwa uwagcine ezindaweni ezinokukhanya okuqondile ukuze ugweme ukususa umehluko ophelele.
Ukukhanyisa okuqondile: Uma umthombo wokukhanya uqinile, sebenzisa ungqimba lwamalambu kumodi Yesikrini ukuze uthole ukukhanya okuthambile noma i-Glow Dodge ngokuqhuma okunamandla. Ngivamise ukugcinela amazwibela angeziwe wamehlo noma ama-spotlight accents. ukugcina okusele matte ukugwema ukulahlekelwa ukuhambisana kwezinto.
Ukuthintwa kokugcina: lawula ukujula ngokuqeda amanzi nokuthambisa izindawo ezikude, futhi wenze ngcono indawo okugxilwe kuyo ngemininingwane eyengeziwe ezindaweni ezikhanyisiwe. Ungakwazi umbala ubuciko bomugqa ezindaweni zokukhanya kwelanga okugcwele thambisa i-contourNquma emaphethelweni aqinile noma athambile kuye ngezinto ezibonakalayo: amajazi aminyene adinga izithunzi ezibukhali kancane kune, isibonelo, unqenqema olucijile lwesithunzi esibonisiwe esilevini.
Izindlela ezingcono kakhulu zokuhlukanisa umlingani ongashintshi
- Gcina ukukhanya okukhethekile kuphansi noma kuvaliwe ngaphandle uma impahla ikudinga; uma kukhona ukukhanya, makube njalo umfutho obanzi futhi ophansi (Ukuqina okuphezulu ku-PBR). - Buyekeza amaphasi e-alpha nesithunzi lapho uqamba; ukuhlukanisa ubuhle namathunzi kunikeza ukulawula okuhlinzayo. - Beka kuqala ama-mascara ethunzi aphindaphindwe ngokugeleza "okungakhanyi".
– Ekwenzeni imephu yemibala enolaka (ecacile), qinisekisa izinga elimnyama futhi ucabangele izinketho njengokuthi “Ungaphazamisi imibala”. Ukucindezelwa kobubanzi kungageza izithunzi– Ku-PBR, kala ubulukhuni ngokucophelela: izinguquko ezincane zikushintsha kakhulu ukufundwa kwe-"matte". - Gwema i-ZTransp yokuhlehlisa ngokomzimba; sebenzisa kuphela uma isivinini sibaluleke kakhulu kunokunemba.
- Ezigcawini ezine-SSS, linganisa irediyasi ehlakazekayo; i-SSS evezwe ngokweqile ingavela “i-waxed.” - Uma udinga "izithunzi kuphela," thembela kuyo Kuphela Shadow/Cast Kuphela kanye ne-matte wrappers. - Ku-Toon, bhala umkhawulo okhanyayo kanye nemaski yesithunzi ukuze ugcine isitayela ngaphandle kokuvula i-Lambert.
Lolu hambo lukunikeza ibhokisi lamathuluzi eliphelele: kusukela kumamodeli ahlukene abonisayo nezilawuli zethunzi ku-Blender, kuya ezintweni ezingakhanyi ezinezithunzi ku-Unreal, ama-matte wrappers ku-V-Ray angamoshi ingemuva ngisho nange-exponential, ukuya ekuphathweni kwempahla kanye ne-PBR ku-Rhino kanye nokucabanga kwevolumu ku-2D. Uma wazi ukuthi ungaphindaphinda kanjani futhi kuphi isithunzi, yimiphi imingcele evala umphumela okhethekile, nokuthi imephu yombala ishintsha kanjani umbala omnyamaOkubalulekile kwe-matte kuba okubikezelwe futhi kunhle kunoma iyiphi ipayipi.
