INT_DIVIDE_BY_ZERO in Process Octane Passes on a default single-cube scene, single GPU or dual GPU, beauty only exports just fine, any multipass fails

7985WX, 256GB, 2x 4090, fully patched W11, 610.88 studio, 1.94 octane, C4D 2026.3.4

Anytime I set a multipass output it crashes. Originally thought it was cryptomatte, turns out its any multipass at all. Beauties render fine. Cant submit the full bug report right now. But some quick reference mentioned problems with the high thread count.

Hi,

Are you sure to have shared the proper c4doctanelog.txt file?

Could you share the scene that is crashing for you?

Sent you DM with logs and default scene it happens in for me.

*edit Attached log here, seems its clean from project details

Thanks!

I have answered you via private message.
