HDRI Lighting is not being applied. My mesh is just a simple white base material.

Describe the bug When I drag and drop a HDRI to the window after loading my mesh, the HDRI appears, but it doesn't affect the lighting in any way.

To Reproduce Steps to reproduce the behavior:

1. Open the .obj file I've attached.
2. Press H in F3D and enable both HDRI options.
3. Drag an HDRI to the window to load it.
4. Notice that the lighting has not changed nor does the mesh respond to the new HDRI.

Expected behavior I expected the lighting to be reflected in the rendered display.
