How do you adjust sampling rate for fire (light) using std volume medium?

Hi coilbook,
I’m not sure what you mean by "adjust sampling rate" in this panel.

Hi Paride,

Like all lights and emitters in octane have this but there is no sampling rate for fire light.

Also do you have any tutorials or samples how to use vectron to generate landscapes like grand canyon and using only procedural shaders. For some reason vectron displace for image textures cannot be found where image projection can be used .

Also how to convert any mesh to vectron mesh

Thank you!

Octane Vectron is great but can we get easier UI and the way to use it?

Octane still renders itoo preview proxy meshes as proxy meshes. Only itoo point cloud mode works

Hi coilbook,
could you share a scene with this issue?

Hi coilbook,
You can’t use a mesh directly in Vectron, you first need to convert it to an SDF, and then use the Vectron (Node) modifier from the Octane Vectron Operator menu.
