Adding Normal Maps to Objects

[𝖙𝖋𝖈]

Hey guys,

I'm using Sketchup to do track objects and there is no method I can see of adding normals while texturing. When I export - I export as .dae including textures, convert that to .fbx and then run fbx2edf.. Long winded!

When I convert .dae to .fbx, it creates an 'Output' folder with my .fbx and a folder full of textures, changing these textures at this stage, then running fbx2edf doesn't seem to use the changed textures, I guess because they are packed inside the .fbx so it uses the originally exported ones..

Is there any way of adding normals to my objects using this method? Or am I screwed.. Right now any kind of building looks like a cartoon!

Thanks
