Unfortunatly not working. It's a clean install, mmh, is there a conflict between old program. I still have 4.8 installed!?
Really weird but in this case not worth an upgrade.
EDIT:
I tried 2020.40 and this one gives an error and kills the voxel part entirly.
Dont know if this is related to my problem. The newer versions gives no error but neither the surface nor clay engine works.
