Normal map question

Turoid

Hey guys,

I got some normal map questions..

For example, I have a wall with a tiled brick texture on it. I also have a normal map to use with the brick diffuse. Now.. can I just tile the normal map too just like the diffuse? I did some test with it (with virtools) but it seems that the surface is moving and shifting when using overlayed uv's for the normal map.

Thanks!

It should work fine, as long as you made a tangent space normal map (should be mostly blue in colour). If you made a world space map (more rainbow-like in colour), you'll have problems when you rotate the model.

Its a tangent and works indeed properly.. It was more of a sort of 'optical illusion' haha..

Make sure it isn't using a parallax shader, instead of a normalmap-only shader. I've seen major "swimming" with parallax, could be what you're seeing.
