mental ray 有沒有一個funciotn 像 maya layer sharde

[cppong1117]

我在maya 入面 用了mental ray 的misss_fast_skin_maya去做了人面的貼圖，之後發覺了，不夠用想加多1~3 層，想用layer sharde，不過用了就show 唔到d texture 要點先可以做到我想要的校果？or mental ray 有類似layer texture 這個function 嗎？？

我全部分開哂唔同既 render passes 黎做, 最後先 comp 埋一齊, shader 太復雜 mr 有時會有問題


不過你指既 mapping 系咩? 系半透既血管定系指臉上既 texture?



p.s. 呢個 week 我又冇電腦, 又冇得上網, 幫唔到你試添

我系想做像真人的皮膚，做來做去都不像，都沒有好的教學，所以問了一些學美容的朋友，get 了一些 皮膚結構圖出來，想試下照往來做，希望出來的效果會比較好！，所以就要比較多的sharder.

Check out the free tutorials on SSS at Gnomon, they are very nice and should be able to give you a good starting point.

P.S. And for your MR layer shader question, you can download the mix8 layer shader. But the only drawback is, as the name suggested, you can only have 8 layers and it might not work with sss well (sss is always a tricky thing in Maya...)
