vTools- Perform CMD on specific layer sets

m4dcow

What I want to do in vTools specifically is invert the green channel of my normal map set.

I'm a Maya user and currently my workflow for getting images ready for UDK is output everything as usual, then copy to another folder for UDK, then manually invert the green channel for normal maps. I would like to skip the step of copying files over and inverting.

There are other ways around this for me like baking maps differently, or changing maya tangent space etc... But I figured the ability to run commands on specific layer sets would be useful for other things.

I could go hacking around in the script, but I was wondering if the script has this functionality, or if anyone has come up with a solution.

two wrongs zero rights etc. if you have to flip channels you're baking wrong. all you gotta do is change the coordinate system.

I mentioned doing that that, but it will get old really fast having to change the handedness on every mesh in maya.

I swear UDK has an option to invert green channel. Anywho I just do the inverting in UDK, just multiply by 1,-1,1.

EDIT: It might be with FBX.

Yeh it is only in the fbx import dialog, it would be cool if they the same thing in the texture import dialog, maybe when you chose normalmap compression it would enable the option.
