mental ray同mayasoft問題

[jacky1987hk]

我做左個fur毛發的效果~~
但系我用mental ray render的效果比mayasoft模~
點解的?
我用mental ray~是想用魚眼鏡的效果~~

同埋點解用v-ray render會無曬d毛~得番個波ge???

1. 因為 mentalray 既 filter 比 software render 大, 你去 anti-aliasing quality > multi-pixel filtering > filter size 我通常用 1.5 or 2.0

2. 你想搵做魚眼鏡既方法, 定系用左有問題? 之前都有人問 fisheye 問題

3. 你指 vray for maya? 我不嬲都唔覺得佢系一個 stable renderer in maya, 所以冇用過.....

c兄咁~通常點決定個值架~1.5or2

我就系跟住果個做左魚眼~~~~
但系如果唔用mental ray~
用mayasoft~點做魚眼

同埋做動畫通常用邊個render好?
maya soft同metal ray有咩分別呢????

For fish eye render with Maya default, take a look at this: http://www.highend3d.com/maya/tutorials ... l/143.html

The idea is to create the fish eye lens in the scene and place it right in front of your camera so it acts like a camera lens just like in real life, then turn on raytrace to render.

The reason why your Vray render doesn't have any fur is because Maya Fur only supported in Maya default and Mental Ray render.

睇心情..... 睇你想要幾 soft 啦

mayasoft render fisheye.... 以前系放塊 model 上個 cam 前面做折射

數值越細越soft?

The easiest way is to render the fur as a seperate pass using Maya default or MR then composite it on to the Vray render, make sure you render the shadow casted by the fur as well.

~.~c兄唔好意思~~唔系好明

Sorry wrong use of word, should be "layer" instead of "pass". Mean you can use maya soft or MR to render just the fur with whatever shadow that the fur cast on the other objects. Then render just the objects with Vray, then use a composite program like AE to put the fur layer and the object layer together. Is that clear enough?

水兄 has a tutorial on rendering passes/layers with Maya, use the search button la...

h2o兄原來系教師黎架.....勁

[jacky1987hk]

我整到魚眼啦~~~yeah~~
我用sharder 放左系camera個metal ray lens到
但系佢render出黎時~~會放大~
影唔曬我要影ge野~~

有咩方法可以立即preview到個效果~唔洗render果時先見到
例如系個鏡頭到就preview到

我有好多身份.... 教書只系客串下......

mentalray lens 用 raytrace 黎計數, 系要 render 先見到, 你用得多就估到個 cam 位架喇
