hi I'm trying to get instancing to work on animated points with octane. It'll instance the geo once but doesn't update each frame. What is the correct way to set this up?

I had a similar problem and when I changed the rendering mode to full scene reload it start working as I wanted. It may be what you need...

thx Ebo yep that worked... but is there another way? I can imagine fully reloading the scene each frame may not be what you always want. The manual says:

"Any object with available Point Instance attributes loads in OctaneRender® as an instancer, and it renders the object referenced by the attribute as an Octane instance."

but it doesn't say explicitly how to accomplish that.

I've tried messing with an attribute create node, adding an instance attribute between popnet and copy to points, set it as class = point, type = string and pointing that as a path to the instanced object. It was giving errors about it not referencing an available object, which seemed like I was heading in the right direction but can't get it working.

yeah, it seems to me like a brute force solution as well...

The problem is that the plugin can't update objects that don't have a constant topology or the same number of points among all the sequence frames, so I'm afraid that the full scene reload is the only solution currently. A smarter scene update system or a new option in the ROP to configure the objects to be updated are planned features for a future release.

Thanks,

OK, thanks Juanjo. I hope that update comes soon.
