Hi Guys,
I have an alembic cache, that contain alembic instance. The cache is loading fine in octane standalone but i can't make motion blur work.
In houdini there is an option to activate to make it work, but i can't find the equivalent in octane standalone ? How would you do this ? is this even possible in standalone ?
Thanks for your lights !
Cheers

well i find where the problem come from.

if you use the houdini orbx exporter, it doesn't export an animated point cloud with ref mesh instanced.
it is basically a per frame export with visibility key on/off, of transform object referencing the ref mesh.

to make it work you have to use the houdini alembic exporter.
you use a copy sop with pack primitive on, then in the alembic exporter you set the Packed Transform option to Transform Geometry.
you store the velocity on your points as a @v point attribute.

and when you load in octane standalone it does work smoothly, with instancing + motion blur.

unfortunatly it looks that octane is unable to understand that it is instance at shader level.
In fact the instance color node and the instance range node, doesn't work, even with the detect instance using checksum option ON in the abc loader.
Random color texture does work fine !
