When I render a plane with a noise shader as a bump, I have the live view looking significantly different from my final renders.

Live view whilst working:

Likely related to compatibility mode, this file is a year or so old.

Do you by any chance have a different scene scale set up in the C4D Project Settings than the default (cm)?

Yes, most of our projects are 10x smaller than default with project scale set to 1mm

Hey Mash, I found the issue: In the Octane Render Settings the parameter "Geometry Control" is set to "Auto Detect".
If you revert this to the default "All Objects Movable" it looks correct again. Obviously should not happen.

I marked this to be fixed for the next release, sorry about the inconveniences.

Another note while doing more testing: If you create a projection node in the noise, it will render correctly. So that's a work-around, too for now, then you can keep the Geometry control at "Auto Detect" if you want.
