I set the scene to a right-handed coordinate system, loaded the GLB model and simplified it, and the simplified result showed that all the surface normals were opposite to the original model, I have a few questions to ask:
- If a model with multiple meshes needs to be simplified, is there an easier way for me to simplify all its meshes?Now I’m using loops to deal with them one by one, which is a bit cumbersome.
- Why is there no problem loading this model in the scene, but the simplified model has the problem of normal flipping? Is it because I got the wrong setting somewhere?
Thank you all.
