Here's a definitely vibecoded version of this that works with latest octane builds, and exports a full HTML searchable copy with tons of info along with a robot friendly json file.

hey!

no, didn't figure it out. i think i found a workaround with rayswitch, but it wasn't optimal.

A file would be good.
One thing that's required with nested dialectics is that they overlap. Do the droplets overlap with ...

Hey Marci!
Did you figure this out?
Sorry - the forum notifications are really spotty for me - usually you will get much more immediate response on our discord (at least from me)

yea, it's not heavy scene, only about 3gb vram are used.

houdini gives this error:

*** OCTANE API ERROR: CUDA error (700) on device 0: an illegal memory access was encountered
*** OCTANE API ERROR: -> failed to launch kernel(kernel37)
*** OCTANE API ERROR: device 0: path tracing kernel ...

getting an error telling that i ran out of GPU memory when using curvature node while using texture displacement.
is this a known bug/limitation?


Heyo!
I am not aware of a bug like this - but I will have a look here in a bit.
Does this happen when your ram is still very empty?
Are there any ...

Heyo!
I'm curious - are you still experiencing this issue now?
