Normal Map Error Color Change

Wonkey

Using 3ds Max 2013, I was rebaking an object. The normal map has changed color, dramatically. I am trying to figure out what is going on. The lighter map is wrong in UDK. I am not sure what to look up to understand this problem.



I have been trying to bake cubes with different settings to recreate the error, but no luck.

That's gamma corrected. I think someone else posted a similar issue a few days back, you may want to look at Max's gamma/LUT settings.

Odd I have it off... I thought


Still throwing out the liter Normal map

I think this is the same problem I had... I want to say I fixed it by un-checking stuff related to alpha. Especially the Pre-Multiplied Alpha

I had the same exact problem a while back. the solution for me was to change the background color of the normals map in the render to texture dialog to complete black.

Failing that, export everything to .OBJ, import into a new scene and try again.

Thank you guy! I had to go with Computron's solution and export as obj. I wish I knew what happened to cause the issue...

I get this when there is something to do with opacity on my model or something - I cannot recall exactly what it was last time. Have a dig around for anything wierd in your opacity on HP or LP etc.

Ok, it APPEARS that the issue is the render Height Map into Alpha is getting checked at random. If I make sure it is unchecked, the normal map comes out as it should.
