Very good work on this 🚀 👀 that was quick
Other than the comments I added, I feel like it would be a good idea to split the shadow atlas resource and plugin into two if you implement it like this.
The code is already quite complex as it is, and with this you're essentially merging two different rendering phases into a single one. It would be simpler to read and understand if they were separate, I think.
Maybe a spot_shadow_atlas and a point_shadow_atlas? Or should we keep it as is?
