Set PSD Alpha by MEL

Hi there,

How would one change the following attribute via MEL?

The script editor spits out "AEpsdAlphaToUse filename.alpha;"

But I can't see any variables or ways to use the AEpsdAlphaToUse command.

No, the AEpsdAlphaToUse ist just the wrapper that is used to issue the actual command from inside the Attribute Editor.

You change the attribute like you change any attribute on a node:

setAttr -type "string" nodeName.alpha "AlphaChannel Name";

Where nodeName is the name of the psdFileTex node and "AlphaChannel Name" is ... well... the name of the alpha channel you want to set.

You will notice, when changing the alpha channel this way, the current/new alpha channel is not reflected in the attribute editor. It is applied to the texture though.
