Hi,
I have an issue with exported ORBX scene from Blender:

- I render an animation with moving object in Blender with selected "Movable" option in render options. Scene compiles only once in the first frame. This is ok!
- The same scene exported to ORBX and opened in Octane Standalone compiles scene every frame.

Is it normal or is this a bug in export module?

I was wondering about this myself... I am preparing a huge test with all types of object to see how they behave on the varius combination of animation/mesh type

Standalone does not support any of these geometry types. Where have you ever seen the "geometry type" attribute in standalone geometry nodes?
This is just how the plugin translates the host application's geometry node graph into Octane node graph during every frame translation, optimising the animation rendering performance. So, only the plugin can make the decision of "translate this geometry one more time every next frame" or "leave this geometry as is in every next frame and save the translation time". This is well described in the plugin's manual.

I haven't, I'm writing about Blender ORBX exporter.

So summing up... An animated object from ABC file in standalone will be compiling scene every frame?

Are you opening this ORBX in Blender after exporting?..
ORBX is an Octane standalone format, it is nothing to do with Blender. Blender just offers you an opportunity to export the Blender scene into ORBX, translating the Blender's nodegraph to Octane format nodegraph that standalone can understand.
So, if you are talking about rendering ORBX - you are talking about standalone.

Octane standalone does not have such setting as "geometry type". So, if e.g. you export all geometry as "Global" and some of this geometry is animated - you will end up with the geometry re-evaluated every frame in standalone. Read please the section of the manual about geometry types...

I'm getting an impression we can't understand our points exactly
Let me get it simple:

1. I'm exporting an animation in ORBX file from blender using this options: 2. I open ORBX in standalone application.
3. Scene compiles every frame in standalone – this is waste of time.
4. In Blender scene compiles only once – this is great.

So far I understand that only in Blender scene will not be compiled every frame?
Is this possible in standalone app or not?
