hello,

our team make 3d engine and we have a little problem. I mean we
debate on using normal map + bump map or only convert combine somehow
bump+normal ma and use only this normal map. what do You think about?
is this a good idea? how modern engines do this? they use normal+bump
separately or only combined normal with bump map??

And some question about 3dsmax. can I combine somehow normal and bump
map in max? or must i use some external software?

thank for reply

If your engine support HLSL/Cg/GLSL then you shouldn't worry about it since possibilities are endless. Remeber one is model-independant and the other is model-dependant. So from renderpipeline point of view it doesn't matter as it all goes into the GPU. So depending on the shader you write to render the model, you might have normal maps, (and many others).
