mental ray, Vray render問題

[superchanchan]

想問下如果用mental ray 或者 Vray render 時候唔用mental ray同Vray material...而系用普通material~~會唔會無咁好?
同埋用左mental ray同Vray material又有幾大分別? thx

plugin renderer既materials(e.g. vray materials.mental ray shader),
原本意義系配合本身renderer既 rendering特性.
如. VRay Mtl, 有glossy reflection, translucency(vray sss), displace and etc 可以配合vray,
而default render系做唔到 or做得唔好.
仲有,
vray一定要用 vray material先可能output到 render element來comp野.
用default materials就唔得.

如mental ray又系,
mental ray shader.eg....occlusion, dielectirc materials,
做玻璃,做GI layer. 一定要用mental ray materials.

如final render,
用fr advanced materials, 可以set blurry reflection,
advanced reflection內面又可以set dispersion, ultra blur(做玻璃),
仲可以set埋 material send GI and receive GI既數量.
fr advanced material 做GI會快過用default material.
final render出哂名多野set.

如brazil advanced,
brazil skin可以好快咁做出唔錯skin material 既效果.
brazil velvet, 做布質感就最正.
brazil car paint做車surface都唔錯.

如maxwell,
佢d shader 超正,
叫BRDF (Bidirectional reflectance distribution function)
assign左, 唔洗點set, press render,
render出來既野好真, 不過就好耐,
用default material來render都得,
不過就用唔著maxwell特有既光學計算方法.
出來result唔夠好,
maxwell打燈一定要用material light等等.

我地用max做render,
好多時會成日轉or試哂咁多種renderer,如,vray, final render, mental ray, brazil renderers.
有時為左方便d, 盡量都會用返default materials,
咁樣點轉render都可以support到.
其實高手系會用default material來做到最好既render效果.

當然, 有時一定要用某renderer material先可以做到某些效果,
eg.我要用mental ray SSS先可以 render到適合既質感,
咁就要用死mental ray SSS materials.

i hope u can figure out. wish this help:)

哦~~好好ar~~明白了
想問下你有無d好ga 3ds max mental ray教學~~最近想用來render一d室內景...同埋一d展覽ga booth等等~~thx

o~~thx~~
重想問下如果用返3ds max default ga renderer...唔用mental ray用Vray...有無方法都可以render到用mental ray同Vray富有空間感ga render~~

why not?
