Ib qho kev pib tshwm sim
Koj tau siv sij hawm raws li cov sij hawm ua qauv rau ib qho chaw. Koj tau UV txhua lub cuab tam, koj textures ua zoo heev, koj zoo siab nrog qhov scene teeb pom kev zoo. Koj nias lub luag haujlwm thiab tos-thiab tos-thiab tos. Thaum kawg, tus kav tiav. Thaum kawg, koj tau qhib koj txoj hauj lwm thiab saib cov duab tiav.
Tab sis koj coj cov ntaub ntawv, thiab cov hauj lwm disappoints. "Kuv tau mus qhov twg?" Koj nug koj tus kheej. Txawm hais tias nws tsis yooj yim sua rau kuv qhia koj tias lwm yam ua yuam kev koj tau ua raws li txoj kev, kuv tuaj yeem taw tes tawm yam tsawg kawg yog ib qho tsis txaus siab:
Koj cov khoom nyoos yuav tsum tsis txhob yog koj cov duab kawg
Kuv txhais hais tias! Nws tsis txawv npaum li cas lub sij hawm koj siv tweaking koj cov teeb pom kev zoo , muaj pes tsawg leeg, thiab kav nqis-muaj ib txwm, ib txwm, ib txwm ib yam dab tsi koj ua tau tom qab-ntau lawm kom koj cov duab zoo dua. Xwb li tom qab ua hauj lwm hauv Photoshop yog qhov tseem ceeb ntawm cov kws yees duab cov duab ua haujlwm, nws yuav tsum yog ib feem ntawm koj li. Nyob rau hauv qhov tseeb, nyob rau hauv ntau txoj kev, lub post-processing workflow rau CG ntxias yog heev uas zoo sib xws rau ntawm ib tus kws yees duab.
Qee yam ntawm cov tswv yim koj siv tau los qhib koj lub hauv paus kav rau hauv daim ntawv tiav:
Tso Cai Ntxiv:
Puas yog koj qhov kev xav hauv scene zoo li nws tsis muaj kev totaub lossis tob tshaj plaws? Ntxiv qee qhov ntxiv qis dua rau koj txoj haujlwm ua haujlwm yuav pab tau koj cov nyom kom yooj yim.
Yog tias koj cov khoom thiab cov cheebtsam tsis xav hais tias yog lawv nyob rau hauv qhov chaw sib koom ua ke, ua rau muaj kev thab plaub tso tawm thiab muab tso rau saum toj ntawm koj qhov kev ua haujlwm tuaj yeem ua haujlwm zoo. Ambient occlusion tsim dab tsi ua yeeb yaj duab hu rau "ntxoov ntxoo," kom tsaus nti nrib pleb thiab kiv cua uas muaj ob yam khoom tuaj ua ke los sis sib thooj. Ambient occlusion ntxiv tau hnyav rau koj qhov chaw, ua kom koj cov ntsiab lus pop, thiab ua rau nws zoo li yog tias koj tus qauv yog ua tau tib lub chaw peb qhov chaw.
Ib qho ntawm ambient occlusion: Rendering tawm tus Z-tob kis tau muab koj lub sijhawm los ntxiv qhov teebmeem ntawm qhov teebmeem hauv Photoshop lossis Nuke, thiab ua kom muaj xim daim ntawv qhia (uas yog xaiv ib qho npog xim xim rau txhua qhov khoom hauv koj qhov chaw) muab rau koj ntau dua masking tswj hauv tsev xa.
Koj tuaj yeem siv koj daim ntawv hla tuaj ntxiv yog tias koj xav tau qhov kev xav tau, rho tawm cais cov kis mus rau cov duab ntxoov ntxoo, tawm suab, thiab cwj pwm thaum koj pom zoo. Siv qee lub sij hawm los nyeem thiab xyaum ua tej kis nrog-nws tuaj yeem qhib qhov rooj rau ntau ntau ntawm cov khoom.
Kov nws
Tsis txhob ntshai tawm tsam cov laus Wacom thiab siv Photoshop pleev xim, overlay textures, thiab ntxiv cov teebmeem los pab coj koj daim ntawv rau nws lub xeev kawg.
Muaj qee yam uas tsis tshua yooj yim los yog siv sij hawm ntau heev los mus rub tawm hauv kev haus luam yeeb, hluav taws kub, plaub hau, cov teebmeem volumetric, thiab lwm yam. Yog tias koj xav tau cov no hauv koj daim duab tab sis tsis paub yuav ua li cas los tsim lawv koj 3D pob , tsuas ntxiv lawv hauv tsev xa!
Kuv paub tsawg kawg ib los yog ob tug yeeb yaj kiab uas yog zaum kawg hauv kev xa ua tiav yog mus dhau ib daim duab nrog ib qho "txhuam" zoo heev hauv Photoshop ntxiv ib txheej huab cua me me ntawm plav plua plav. Nws yog ib yam uas siv sij hawm tsawg kawg los ua kom tiav, tiam sis tuaj yeem mus rau txoj kev coj mus ua kom tau ib tus duab rau lub neej, thiab nws yuav tau nyob deb, tsis yoojyim ua kom tiav hauv lub pob 3D.
Koj tsis tas yuav ua raws nraim li, tab sis sim paub seb koj yuav siv cov Photoshop rau koj kom zoo dua! Tawm hauv textures los yog lens flares, pleev xim tawm artifacts, ntxiv ib co yeeb yam los ntawm tsab ntawv tsa suab blur. Tshawb nrhiav koj tus duab zoo li tus kws yees duab yuav xav tau ib daim duab duab, thiab nug koj tus kheej, "dab tsi yog qhov duab tsis muaj, thiab kuv ntxiv tau yam tsis rov qab mus rau kuv pob pob?"
