Going slightly mad trying to figure out why RNDR is rendering duplicate frames pretty much at random, from an orbx file generated in C4D R20. The frames are numbered correctly, but the render created for frame 48 (for example) will be the same render for frames 49, 50, 51, 52 -- then frame 53 will "catch up" to the animation and render properly. This will happen in 3 or 4 places across a 96-frame animation.
I'm on Windows 10, using OctaneRender for Cinema 4D 202.2.3-R4.
