Mesh Simplification Workflow

tach

Hi, I'm currently trying to create a lower poly version of an already textured low poly. Not a lod but rather a new base low poly.

My question is regarding what would be a clean/optimal workflow to transfer the normal map from the original mesh to new one without creating random issues with the normals. Ty!

Quack!

You won't be able to do what you want without busting the normals. Normal maps are baked with the low poly's information in mind. If you change those, you break the normal map. You need to transfer the normal map from the high poly.

You can simply bake a new normalmap from the highpoly model to the new lowpoly model, or, you can apply the existing normalmap to the original lowpoly, and bake that to the new lowpoly. Both should work.
