Can't I Just Use My Bump Maps?
« on: April 15, 2014, 09:04:08 am »

I convert the bump maps I created for my model to normal maps using Nvidia's converter, but I don't seem to achieve desired results. In fact, I doubt I really get any result at all.

Can't I just use my grayscale bump maps instead?

You could try manually extracting channels and making them yourself. I think it goes red channel = x bump, green channel = y bump and blue channel = blank (solid blue).

Check the .mtl file of the object folder. If there is no entry for the normal channel (tex_normal) the normal map is not applied to the model yet. here is an example what it must be like. And dont forget to copy the file into the package folder. The dds format must be bc5, but you will know that probably if you are using nv-converter.

Code: [Select]
"tex_albedo" : "barell_tex.dds",
"tex_normal" : "barell_nrm.dds",
