Incorrect shadows

Open QuimMoya opened this issue 3 years ago • 3 comments

Some models expose incorrect shadows image

This image shows shadows in non-visible faces of the model. Shadows must be applied on the visible faces only

I think that this can be fixed by using 2-face Three.js materials. The problem is that the normal of the faces of the geometries is not correct, and faces with flipped normals are not rendered.

@QuimMoya can you attach the IFC file for reference

@QuimMoya can you check this model again - I think a PR has fixed many issues to do with shadows
