Hi,

our character modeler just asked me a question about the engine that I cannot answer, but maybe you can:

"Quick question: does the engine support mirrored normals? As in, if one half of a model is textured (diffuse and normal map), while the other half is a mirrored copy, will the engine render the mirrored half normally or will it invert it? I've been unwrapping the model in halfs to increase texture space but if the engine doesn't support this i'll have to rebake what i've done so far."

Regards,
Pegamode.

I would say yes. Each vertex has its normal and uv coords independently if they are mirrored from other vertex or not. uv coords are independient from triangle coords, so you can texture a triangle in native texture format or inverted without problems.

I think it has more to do with how your 3d app exports each vertex. If each vertex has its normal and uv coord right, it will render good.

Salud!

Correct. The engine will render the mirrored half normally, as it sees no difference between a mirrored polygon and its original.

Thanks for your answers.
