    im getting this error, Error. Falling back to CPU lightmapper. Error callback from context: CL_OUT_OF_RESOURCES error executing CL_COMMAND_READ_BUFFER on NVIDIA GeForce RTX 3050 (Device 0). I have a nvidia rtx 3050 and when i want to use progressive gpu to lightmap it falls back to cpu. im using unity 2020.3.48f1. Is there any known fixes?

    Make sure you are not using an lightmap atlas bigger than 1024 and I think 2021 has better VRAM handling so you could try switching to that.
