Hi All, I have quite a large number off packed primitives which render fine in Houdini Mantra but when I want to change the render to Redshift . it doesn't work and computer goes to halt mode. checking the windows task manager it shows the memory shoots up to 20GB . how can I fix this problem . Redshift doesn't support packed primitives?

go to your geometry node>Redshift OBJ>Settings>instancing tab. select "Instance SOP Level Packed Primatives."

Does anyone know what the updated way to do this is? My scene has a large packed alembic with around 9000 packed alembics, but redshift is trying to unpack it all with rendering.

if you are in one of the latest RS versions you can try and use the alembic procedural to render.
