Custom render pipeline is not supported in future Unity versions

[stavrohristo90]

It sucks that this is stuck on your custom renderer... The LTS version of Unity with the newest features and improvements on the URP/HDRP is rendered obsolete since the shaders and some dependencies are not compatible. I suggest you open the project in a newer unity (2022 LTS at least) to try and fix these issues since you are missing a lot on performance improvements.

Also why the heck do you need to use a custom renderer? You could have just generated the materials based on a simple forward+ method so we could at least try to experiment with realtime GI or RT ....
