About Octane Gradient, it is a Mapping node not a Generator, so you need to consider it as a Colorizer, than a proper Gradient.
It allows to remap an input texture with desired colors, but in your node setup, the input texture is missing.
Press the Liner or Radial buttons for generating it automatically, or use a graduated texture image or any other texture node to use it correctly.
It could be also used in Complex mode, for more details, please have a look at here:

Thanks Beppe, I disabled all GPUs apart from the VII:

: VII

I will let you know if it crashes again.

Regarding the gradient: Will this speed up performance? I have 20 materials to change, so if it doesn't make any difference I am happy with using the C4D gradient

Thanks again

Ok, keep me informed.
Probably the isue is in the mixed AMD families, Radeon VII is a Vega GPU, while 5300 is a Navi GPU :roll:

About Gradient speed, Octane Gradient + Sinwave should be slightly faster, since there are not any conversions in between.

Disabling all but the Radeon VII definitely helped. I only crashed 4 times yesterday which is great. I'm hoping to get a AMD Radeon RX 6900 XT when they're available, so hopefully the VII+6900 combo will work!

Thanks for gradient tip!

Is it possible for you to export the scene to Standalone, and try to do the same steps with both Navi and Vega GPU active, to see if you have the same behavior as in plugin?
