Hey @squidring ,
Are you creating an underground rave?
If so, this works.
If not, make sure the irradiance volume inner cube is only just outside the wall, scale it from all angles (top, side, front).
All the dots should be inside the walls.
Your number of resolutions will almost certainly differ from the number Kent uses.
It will depend on what your computer can handle and the overall size of the cube.
Avoid having the dots too far from the wall, but also not too many that they intersect the wall.
I hope this helps.
