AtmosphericFog PreCompute Parameters

Hey guys,

I’m playing around with the precompute params in the atmospheric fog to try replicate what’s happening in the docs [link]](Atmospheric Fog User Guide | Unreal Engine Documentation)
But I can’t seem to get any values working for density height/max scattering or Inscatter altitude. Do I need to do something to run the precompute?
I’ve tried it on 4.4.3/4.5.1/4.6 on windows 8.


looks like it runs fine on my workmate’s computer, same version/OS and drivers, possibly the graphics card or I have edited something somewhere.
