Hi Guys,
Getting Render Failures on a fresh C4D scene with some cached .mdd files. Same in V3.08 and V4.01. Any idea ?
It’s not textured yet. Just imported my .obj and the .mdd files.
It starts rendering in the viewport but after 2-3 refreshes it fails.


Using C4D R20
2x RTX 2080Ti
AMD TR 2950X
X399 Taichi

How many triangles do you have in scene? And how much big for one biggest mesh?

Did you figure out what was wrong? I'm getting the same issues with 3x RTX 2070s. Can't fix it, it's been down all day.

I'm having the same issue on a near identical system I got this weekend. Tried new/old Drivers, Windows refresh, enabling/disabling the GPU... at this point i feel like it's gotta be a faulty card. Realllly was hoping to avoid dealing with manufacturer returns. Luckily one of my two 2080 TIs is working properly.

can anyone try octane 4 RC7 build to see if you have cuda errors or crashes It seems that after this build when all the problems started.

Still having this problem - Did anyone discovered a fix?

were you able to solve it? I have the same problem and it is related to rtx cards. Thanks
