OK. Hopefully, txhua leej txhua tus tau ua raws li nrog thiab tau txais lawv column qauv tsis muaj teeb meem ntau dhau lawm.
Txij ntawm no mus peb yuav pib zais cov av tshiab thiab qhia UVs, textures cov tswv yim , thiab cov teeb pom kev zoo los txhim kho rau cov txheej txheem uas peb tau tsim hauv zaj lus qhia dhau los .
Thaum kuv pib hauv 3D, kuv pom UV Mapping txheej txheem los ua ib lub tswv yim toughest los qhwv kuv lub taub hau, uas yog vim li cas kuv xav tias nws yuav zoo pib nrog ib yam zoo li ib kab.
Rigid thooj voos kheej kheej yog nyob deb ntawm qhov yooj yim cov duab los tsim ib qho zoo UV kev teeb tsa rau. Thaum kawg peb lub hom phiaj yog "daim ntawv qhia" ob sab duab rau saum nplaim peb sab, thiab kom ua tau li no, peb yuav tsum qhia cov kab ntawv hauv 2D coordinates.
Yog hais tias koj xav tau ib qhov tob tob ntawm UV kuas, peb mus rau qhov tob tshaj qhov ntawm no .
Unwrapping lub Cylinder
Rau peb yuav tsum tau thov ib daim duab thaij duab rau peb tus qauv, peb yuav tsum tau ua kom tus qauv ncaj nraim rau UV cov hauj lwm. Maya's UV cov cuab yeej muaj nyob rau hauv khawm polygon, raws li cov khoom noj Tsim UVs thiab Kho UVs .
Yog hais tias koj qhib lub tsim UVs zaub mov, koj yuav pom tau hais tias muaj plaub loj hom UV maps uas Maya tau cia li tsim: Daim phiaj qhia maps, cylindrical, kheej, thiab automatic.
Nyob rau hauv cov ntaub ntawv ntawm peb sab, peb yuav siv cov cylindrical daim ntawv qhia cuab tam (rau qhov laj thawj zoo.
Xaiv qhov cylindrical feem ntawm koj kem, thiab mus tsim Tsim UVs> Cylindrical Map los tsim ib daim qauv rau koj tus qauv. Tsis muaj dab tsi yuav pom qhov hloov ntawm tus qauv, tab sis tus neeg siv yuav tsum tshwm sim.
Los ntawm kev pheej hmoo, lub cylindrical mapping cuab tam tsuas maps ib nrab ntawm lub tog raj kheej-nyob rau hauv kev txiav txim rau ob tog ntawm cylinder kom haum rau peb qhov chaw UV, peb yuav tsum tau hloov ceev.
Ntawm qhov nruab nrab ntawm lub plhaub taum, yuav tsum muaj ob qho quav liab rau ntawm UV qhov hluav taws xob. Cov saib xyuas no txiav txim siab tias ntau npaum li cas ntawm lub tog raj kheej yuav zoo rau 1: 1 UV chaw. Nias ntawm ib qho ntawm cov xim liab thiab rub nws tawm ntawm lub teeb xiav xwm yeem mus txog thaum ob lub lag luam liab tuaj ua ke.
Saib seb koj daim ntawv qhia UV zoo li cas, mus rau Qhov Ncauj> UV Kev Npaj Editor thiab xaiv lub cylinder.
