Title: Damn normal maps
Post by: TrashMan on July 14, 2009, 07:19:33 am
It's been a while since I made a few, so now I hit a stupid brick wall.

I got Crazy Bump and  I started with the usual procedure - make a heightmap, generate a .tga and use Photoshop NVidia plugins to convert it to DTX5 normal map.

Except it doesn't work anymore (now I got a ATI graphics card) and any other method I tried of generating a .dds has the same result - a normal map that freespace apparently can't use .
It pisses me off.

Anyone got nay ideas? I attached some files (heightmap needs resizing to 512x512 :P) if anyone cares to look.

Huh? Surely saving as a DXT5_NM is possible in PS even with an ATI card. This normal map I see has simply in the DXT5 format - not DXT5_NM. The difference is only in the channels used - from the normal map you have, the Red channel becomes the Green, and the Green channel becomes the Alpha, while it doesn't matter what you leave in the Red or Blue channels. That's all saving as DXT5_NM does anyway so even if it doesn't work for whatever reason, you can still do it manually.

I had converted this map from .tga version to DXT5n, it works and it's much better than the one I made.
I would like to ask you for premission to use your normal map for BP.

Sure. That was a test..
I might end up tweaking the map later.
