Photoshop Breaking Normal maps

SpeedyB

I've been having some trouble with normal maps in Photoshop. Whenever I open a baked normal map in Photoshop and modify it (add details etc.) and save it, the normal map no longer works properly in Max (Xoliul shader).

In this test image I baked the normal map and applied it to the first object. For the second object I opened the normal map in Photoshop and saved it without changing anything. The map was baked to .tga and saved by Photoshop as .tga 24 bit.


There must be some setting I have set up wrong or something. Any help would be super appreciated!

Do you have gamma/LUT enabled in Max? If so, disable it. Xoliul doesn't like it.
Try restarting Photoshop if that doesn't help, too.

I think someone here recently had a similar problem, and (for memory) it had to do with photoshop having some form of colour profile enabled.

Have you renormalized the texture before exporting? (and after editing)

It was gamma/LUT. I feel like a moron :P
So its either a dark scene or broken normal maps. I hope Xoliul makes a new version of the shader and fixes that.
