Uchungechunge lwe-Shader Recipe
Ngaphezulu lapha ekhoneni lamagajethi, izindlela zokupheka azikwenzeki ngempela, kepha kwenzeka kimi ngobunye ubusuku ngenkathi ngimbela iseluleko sokupheka inkukhu ye-lemon pepper engingayenza uchungechunge oluqukethe uhlobo oluthile lwe-recipe - zokupheka ezithuthukayo .
Zonke "izincwadi zokupheka" ziye zabhalwa ezintweni zokwakha kanye nezithunzi eziseMaya, UDK, 3DS Max, Vray, njll.
Kuyinto engabadlali abaningi abaqalayo abanenkinga, futhi ngesizathu esihle! Ukwenza imingcele ye-arcane efana ne "amandla angacacile" kanye "nesisindo somzimba" emzamweni wokulingisa izinto zangempela zomhlaba njengezinkuni, ingilazi, itshe noma i-ceramic tile akuyona umsebenzi olula.
Ngakho, lapha silapha.
Kusukela ngokungahlali kahle, sizoqala ukwethula ezinye izilungiselelo zohlelo lokusebenza ngezinto ezithile ezivamile zomhlaba wangempela ezinzima ukukhohliswa. Ngokuyinhloko sizosebenzisa iMaya kulolu chungechunge, nakuba singangena kwi-Unreal Development Kit isikhathi noma ezimbili. Sijabule ngalolu chungechunge futhi silindele ukufunda okuningi ukubhala njengoba ufunda!

Kuyini i-Ambient Occlusion?
Ungavumeli ukuthi igama lakho likukhohlise-ukukhishwa kwamagama okuyiyona into ehle kakhulu yokwakha, futhi kubaluleke kakhulu.
Akuyona nje i-AO esetshenzisiwe (enhle yonke) ekuhlinzekeni izithombe eziqhubekayo emsebenzini, futhi iphinde isetshenziswe njengesisekelo sokusika umdwebo we-composting kanye nokuthungwa ngoba kusiza ukuletha imininingwane kanye nezinto "ezisemhlabeni" endaweni yesehlakalo ngokuhlanganisela izithunzi .
Ukwenyuka okuvamile kuyindlela yokwenza izinto ezizimele, okusho ukuthi isebenza ngisho noma kungekho ukukhanya endaweni yakho. Ngokweqile, kungukulinganisa okulinganiselwe kokukhanyisa komhlaba jikelele, futhi kusho ukulingisa indlela ukukhanya okusabalala ngayo ekamelweni noma kwendawo.
Ukubukeka okubi kakhulu kwezinto ezibonakalayo kunezici "ukubukeka okuthungile" ngokubumnyama okucashile noma yikuphi lapho kuvela khona izimbalwa ezimbili noma ukuxhumana (amakamelo ekamelweni, ngaphansi kwezinto, imininingwane emihle, njll). Imifanekiso yokumnyama embi eye yabizwa ngezinye izikhathi ngokuthi "ubumba bubumba" ngenxa yokuthi kufana nokufana nobumba.
Nansi imodeli engiye ngayenza yokusebenzela ngonyaka odlule osebenzisa ukungabonakali okukhulu ukuze kuboniswe uhlobo lomfanekiso (umqondo wezikhali nguG Diego Almazan).

Ukudala i-Ambient Occlusion Shader:
Ukudala ukuthungatha okubonakalayo kokuthutha kwezithombe eziyisisekelo zentuthuko kulula kakhulu, futhi akudingi noma yikuphi ama-UVs, amabalazwe okuthungwa , noma ukukhanyisa.
Kunezindlela eziningi zokuqalisa umphumela wemiphumela ehlukile, kepha leyo engizoyiveza lapha iyinhle futhi iqondisa kahle, idinga kuphela i-node yama-Ray eyengqondo kanye nesakhiwo esiyisisekelo seLambert.
Nasi incazelo emfushane ngesinyathelo.
Vula iwindi le-Hypershade bese udala indaba entsha ye-Lambert.
Nikeza igama lakho igama-Ngivame ukusebenzisa into enjenge- ambientOcclusion_mat .
Chofoza kabili indaba ukuze uvule izimfanelo zayo ezibonakalayo. Yilapho sizobeka khona kakhulu imingcele ye-shader.
Ngokuzenzakalelayo umbala wezinto ezibonakalayo uyimpunga engathandeki, kodwa asifuni ukuthi izici zethu ezivelele ziphume, ngakho-ke sizobe slayipha inani lemibala phansi ekugcineni komnyama. Sisebenzisa u- 0, 0, .38 ngenani le-HSV kumbala wombala , kodwa lokhu kuyindaba yokuthandayo.
Into elandelayo okudingeka siyenze ukufaka i-node encane yokungena embonweni we-incandescence.
Chofoza ibhokisi elibukeziwe eceleni kwe- incandescence input. Lokhu kuzoletha iwindi le-node yokunikeza.
Ngaphansi kwethebhu ye- Ray Mental , chofoza imidwebo bese uthola im_b_amb_occlusion ohlwini. Chofoza, futhi i-node izovulela kumhleli wesici ngakwesokudla kwesikrini sakho.
Kufanele ubone uhlu lwezimfanelo-lezo ezibalulekile kithi amasampuli, ezikhanyayo / ezimnyama, ezisakazekayo, kanye nebanga elide, noma yikuphi into esizoyishintsha yilezi zampula.
Esikhathini esivumelana nesimo se-occlusion, inani lamasampuli lilawula inani lomsindo ekunikezeni kwakho.
Ukushiya amasampuli ku-16 noma ku-32 kuzoba okulinganayo, kuyilapho ukufaka inani ku-64 noma 128 kuzobonakala kubushelelezi. Amasampuli angu-32 anhle ukuhlola, kodwa uma ngihlela ekuboniseni isithombe ngizosebenzisa ngokujwayelekile 64 noma 128.
Zama imibala embalwa kumazinga wesampula ehlukene ukuze uzizwe umehluko-ungathola ukuthi uthanda ukubukeka kwe-grainy ngasekupheleni kwe-spectrum.
Nasi isithombe sokuqhathanisa engasenza ngisebenzisa indawo yangaphandle Ngabe ngibuyele emuva emuva ngibonise umehluko emkhatsini we-Maya basekela, futhi ukufakwa kwesimo sendawo kufana nezibonelo ezingu-64 no-128. Bona ukuthi kungcono kanjani isithombe sibukeka ngesimo esivelele?
Ungadlala futhi ngezinye izici uma ungathanda:
Ukulawula okukhanyayo nokumnyama ukulinganisa okulinganiselwe futhi okuphezulu. Uma uthola ukuthi iziqephu zakho ezivelele zikhishwe noma izithunzi zakho zichotshozwa, ungasebenzisa lawa ma-slide ukuze uhlawule. Ukusakazeka kanye namakhilomitha amaningi kuzoguqula ibanga lokungena / ukubonakala phakathi kwamanani akho okukhanya nokukhanya.
Nakhoke! Sethemba ukuthi ufunde kancane ngokushiyeka okunamandla nokuthi ungasetshenziswa kanjani njengento enhle yesethulo yezingqimba zakho ezingu-3d. Ngazise ebhulogi uma unemibuzo!
