Z-depth in MAYA

[xtu6io666]

請求各路高人 :

MAYA default有咩方法可以直接出到一張有z-depth既data既圖for aftereffetc直接用到而又無aa既問題???

唔用rla, depth shader, fog, ramp......etc

[h2o]

我都想知, 不過近排有時間試下 mental ray, 發覺 mental ray 都系其中一個可行既方法, 識得用的話, 又真系唔太慢...... 不過應用o系 production 上, 我仍然有保留

用rla 就一定得
不過我本人就想用 mental ray 去render, 但佢會出多一個iff file 去儲z-depth 的資料，我都好想知~~ 有乜方法~~

[h2o]

用 rla 就有 anti-aliasing 問題, 而且仲要夾 after effect, 的確系一個難題

有無 MAYA5.0 掛件位置可以下載

.rla maya 本身就有, 系一種5 channels file format 黎架

[yanronald]

再者~~如果用fluid 去做會動的雲, render一定好慢~~
有乜更快的方法？
唔知AE 中可唔可以做到Maya 的效果呢?

or you can try to render your z depth 2 or 3 times larger, then size it down. sometimes it works.

其實Maya 有個shader 可以直接 plug 入個 oject 到. 當普通shader 咁 render 你喜歡既 format , 不用特別 render rla render 完後可以直接放入 after effect 用. 而且系有 anti_aliasing . 系一個非常好既 shader. 雖然小弟知道 Xtu6i0666 兄不太想用 Depth shader,但希望可以順帶一提呢個shader 分享比其他朋友.

你地可以去 highend3d > Maya Shader > search >DepthShader V1.0 佢就可以做到Z Depth 效果... 我亦 share 左呢個 file , 歡迎 download


DepthShader V1.0

this is DepthShader....
because maya internal z-depth is no antialiased image .when you make effect like fog in compositing,
you get low quality image.

this shader give you full rendered z-depth image include antialiasing,mblur...etc.

use depth attribute below extra attributes.

小弟還未打開 但是要向您說聲謝謝

[yanronald]

me too~~ thanks

depth shader 當然可以解決問題, 同 fog 既效果一樣

不過呢條問題系唔用 depth shader, fog, ramp.......
要 maya 直接 output 5 channels (RGBAZ) 既 file, 又要有 anti-aliasing

hehe 有待解答

If Maya works the same as XSI then it will be very easy. Because in Maya's render setup page, i saw a check box called "z channel (zdepth)" under camera.

XSI has the same check box. You only have to check that box, then mental ray will render a seperate file extension as .zpic which you may use this file in after effect. or you may use a .zpic converter to convert this file into a jpg or bmp.

However, i am not sure does that check box in maya work the same as XSI
