Question by QuantumTheory · Mar 19, 2014 at 07:00 PM · texture mesh normalmap normal map surface normal

Export Normal Map from Selected Mesh

I want to be able to select a mesh and export a simple normal map of the geometry in the editor. Unfortunately, I'm not sure how to go about it in code.

I imagine I'll have to iterate over every texel on the geometry and write the tangent of that texel to the texture.

Can someone help get me started? Thanks!
