V3 MultiLayer EXR Workflow - Index Layer only one channel

[regionfive]

Hi,

rendering to multilayer with different passes works fine for the light passes, but the Object Index and MAterial Index are rendered to one channel only. When I open them with Extractor in After Effects I don´t see different colors to distinguish between objects or materials. They rather behave like the depth channel. Whats wrong there?

Thanks.

Edit: Ok, it looks like those channels arent saved and renderd by octane, as there is also no DoF rendered. Blender seems to store those Layers from a viewport render into th exr.
How can we pack those Info channels right into the EXR?
