View Full Version : How to create a new bump map?

10-28-2009, 02:33 PM
I'm using Crzybump to make new/improve the bump map textures of KOTOR. I began with the Selkatch bump map, but every time i load the game it says: INVALID BUMPMAP N_SELKATH01B.TGA. I figured out the configurations of the default bump map with CrazyBump:
1.33 MB
32 bpp
No compression

I made sure my custom bump map had the exact same stats.

But every time the game starts up i get the above error. Any ideas what i'm doing wrong?

Well, this isn't something very general; like 2DA editing or scripting.
Infact I never did something like this, so this a more of a wild guess.

After looking into Lightmaps, I came across a .txi file. The file was named the same as the lightmap.tga.

The TXI file ( just a notepad file saved as TXI) contained a simple line saying that the mentioned TGA should be used as a Lightmap.

Now perhaps the same applies to bumpmaps, so it could be you'dd need to make a TXI file.

Containing this, again this is a bit of a shot in the dark.
Example of m80ab_09b_lm4.txi which is the parnter of m80ab_09b_lm4.tga

islightmap 1
compresstexture 0
mipmap 0
downsamplemax 0

What I suggest for the bumpmap is to alter it to:

isbumpmap 1
compresstexture 0
mipmap 0
downsamplemax 0

Not sure if the last 3 rows of the compress and downsample are needed.

I copied an unaltered version of the selkath bump texture with a TXI with your info and i still get the INVALIDBUMPMAP: N_SELKATH01B.TGA.
