Steps to reproduce:
1. Drag the terrain into any HDRP project (I used just an empty HDRP template).
2. Enable the Baked Lightmap debug mode and change lightmap resolution
Actual results: The debug mode doesnt work for the terrain, the texels are not updated and the baked lightmap intensity slider also doesnt do anything for the terrain. It only works with the cube object.
Expected results: The texels are updated on the terrain object the same way that is being updated on the cube in the video.
Reproducible with versions: 6000.0.22f1
I have tested on builtin RP as well with the same asset, the debug is working there.
