Hey there,
Tried this a few times, but unfortunately it looks like Octane 2019.1.2 , coupled with LW 2019.1.4, doesn't appear to recognize envelopes for emission or density in the volumetric node editor. I'm using the 'update volumetrics' and 'update materials' in the render target( I've tried updating all materials, or just the one in the selected object - coupled with the 'octane object properties' custom tag), but it sticks with the values from the first frame you render, unless of course, you use 'full scene reload', which I've had to resort to. Quite annoying, as I also have objects with a quite astounding number of UDIMM textures in the scene.
This is all using a TFD, sequence BTW, I haven't tried this with a VDB sequence yet.
Anyone found any workarounds? Or had a similar experience?
Cheers
John
