exporting recalculated normals in studio XL

In the optimize in studio XL  InstaLOD doesn't output textures. I'm optimizing an .obj to 5% triangles. I've switched on Normal recalculation. How do I export this newly generated normal map so I can use it with my decimated mesh?

Thank you

René

  Hello René, 

  When you recalculate normals, InstaLOD computes the vertex normals directly stored within the mesh. You could run a bake operation to transfer the normal information into a texture.

  I would recommend the following workflow:

  1. Recalculate the normals for the high-poly mesh using the MTK and export the scene.
  2. Optimize the mesh (without recalculating normals).
  3. Reimport the result from step 1.
  4. Create a bake profile and bake the normal map from the high-poly mesh to the low-poly mesh.

  Thanks,

  Andreas
