bump map doesn't look bumpy or decent Created 14 years ago2010-08-08 02:34:58 UTC by quailcreek

...it just puts a bunch of drak blotches on my texture:Also notice the black pixels here and there. From a distance, I can tell no difference between it and a non-bump version. Up close, the bump version just looks like shit. Is it supposed to look better than this?

Yes, I have the latest video drivers.

Thanks.

show the picture you are making a bump from also.

oh

I made it in the gimp normalmap plugin

Don't.

Learn how to make a proper normal map and then go from there, don't use cheap gimmicks like that.

Hm okay. VDC doesn't seem to mention the method being unadvisable, nor does it cover what a "proper" normal map is and how to make one. Can you point me in the right direction? You say "cheap gimmicks" ...does that mean that the fact that the gimp plugin is free makes it low-quality?

No, it's just that there is no way to tell the coordinates of points from a 2d image, the normal map creation software you used is ok, but the actual way to make a normal map is to make a model with all the geometry you want to 'bake', and the coordinates will be baked into a texture which tells the GPU "Ok, this point on the texture is really far out, but this point over here isn't".

It doesn't actually make or move geometry, it only affects the lighting and shading.

I didn't explain that very well but that's a rough outline of it.
