GPU Lightbuild Button Greyed Out (v4.26.2)


We’re seeing this on our 4.26.2 Editors:

We’ve enabled and tried the following:

  1. Turn on GPU Lightmass Plugin
  2. Changed default RHI to DirectX 12
  3. Raytracing in the Rendering Options Menu was turned on
  4. Tested on 2 different PCs so far. One with a GTX970 and another with a GTX1060

Does anyone have insight on how we can get this to run?

Same problem. It’s supposed to be compatible with GTX1060 from what I’ve read. Other thing is updated drivers. Which mine are.
