I tried searching the site for this problem but I didn't find anything relevant. I'm having problems saving normal map files. The baked ones look fine but when I open the file and re-save it in photoshop it gets a bit distorted. I'm not really sure what's causing this.
The result looks odd, the different uv-shells have different brightness and you can see the edges pretty clearly;
The file dimensions are 4096x4096 and I can't save tga files in anything lower than 16 bit(the baked files are 8bit). I've tried with tif too but I got the same problem. I've been using xoliul shader, maya standard mat render and cryengine sandbox 3 to test this problem.
Does anyone have any clue on what could be causing this?
