I posted this in Technical Support …
Have been using 2.81a also happens with 2.80 but not 2.79b, at some point with Point Density in a Material always crashes. Have also tested both CPU render and GPU with either CUDA or Optix all options result in the same. (Cycles)
Hardware … i9 9900k / Gigabyte RTX 2070 Super.
Wondering if anyone has an i9 9900k + (Gigabyte) RTX 2070 Super having the same problem ?
