[Maya] Relative Transform

Came across this today when needing to resize a bunch of instanced objects for a particle debris explosion:

Select all the instanced objects
Press R for Scale (or any transformation)
Change the Menu of Input Line Operations dropdown to Relative Transform
Change the scale in the input boxes to the right of the dropdown

-- all the selected objects will transform and stay relative to their original values

[Maya] Linear Workflow in Maya 2010

______________________________________
Linear Workflow in Maya 2010
______________________________________
1) モニターカリブレーションをsRGB 2.2ガンマに設定
2) Photoshop等でテクスチャーを作る（イメージは2.2ガンマ）

Maya:
3) Mental Ray Render Settings/Quality/FramebufferをGamma 1.0 RGBA (Float) 4X32Bitに設定　
4) テクスチャー毎に0.4545GammaCorrectノードを掛ける
5) 色・ライト・マテリアルは0.4545を掛ける
6) プレビューの為に2.2ガンマのレンズシェーダーを掛ける (physical sun, physical sky/mia_exposure_simple)
7) レンダーする前、mia_exposure_simple gamma を1.0に戻す

8) コンポジットはNUKE/AEで 32bit Linear Float with sRGB 2.2 vlut

*Maya 2011にはLWF設定があるので、それを使ったほうが便利。

[Maya] broken image plane workaround

Sometimes the image plane just stops showing up in the viewports which can be really frustrating. Not exactly sure what causes it, but it seems to happen on cameras with multiple sub groups when using the mia_exposure_simple lens shader.
If adjusting the near/far clip plane doesnt fix it, the camera is probably broken.

Heres a workaround:
1) Create a new camera
2) Copy all settings from old to new camera
3) Constrain point/orient from old to new
4) Bake keys, delete constraints
5) Create a new image plane
6) Lastly add mia_exposure_simple

-- This basically clones the bad cameras attributes onto a working one

[Maya] Mel Script: Node Select

I wrote this for a friend, will have to remember to translate to english later

１．　Hypershaderを開いて、Nodeを選択
２．　Script Editorを開く（先のCommandが出る）
３．　数字を削除して、Nodeのベース名前だけをコピー
４．　下記のScriptで[Node]の代わりに貼り付ける

select -r `ls -type [Node]`

５．　Script EditorからMel ShelfまでMiddleClick+引きずらしたら、Melボタンが出る

例：
ls -st gammaCorrect1

select -r `ls -type gammaCorrect`

結果：
全部のgammaCorrect Nodeが選択になる

Some stuff ive worked on in Japan so far

[Maya] Render Layers Tip

1) Create multiple Render Layers and assign your objects to them
2) Select a Render Layer
3) In the R.Settings window - hover over an attribute. If an icon appears next to the cursor you can right click and select Create Layer Override.

-- The attribute turns orange and the setting will change only for that particular render layer
