I'm using the pyro explosion material preset,and the aov_scatter/aov_fire aovs are automatically created.But the aovs are pure black in my render.WHY?Karma CPU and XPU are the same.

sorry,it's my fault.

Hey @wanglifu - what was the issue? How did you fix this?

I think this has been fixed in the newer builds. In the older builds the aovs are supposed to automatically get created but they don't. So add them manually on the karma rop and they should be there.

Currently having the same issue in H21 ... All volume related AOVs are black when using the Karma Pyro Shader. Combined Volume and the ones that it makes Fire/Scatter

Other materials like Karma Volume and Karma Fire Material render them fine.



Edit: Ok, so it seems like those AOVs won't work when it's just fire/temperature. They need density.


How do I get an AOV of my flame out of karma?
