Why does Octane load all mats and geometry before rendering?

[mitchino]

I have a c4d scene with lots of Octane materials, meshes etc. Most of these are switched off in the viewport using c4ds visibility buttons. When I fire up Octane, it loads all the unused materials and meshes before starting to render, which makes it slower than the native renderer to produce an initial image.

Can I turn this off and just have it load the items I actually need for the render?

It will not load hidden geometries, please test it again!
But it will load unused materials for LV/PV. There's an option for disable unused materials for PV. This option is not possible for LV by current desing and stability purposes!

Which version do you use? V3/V4? V4 is much faster on geometries.

Thanks - I'm using 4 - will delete my unused materials.

I have posted re light linking in 4 - how does this work?

Set LightID for Octane lights from LightTag, And select which ID will be used for object from ObjectTag's "Light Pass Mark" controls.
