Hi,
Just thought I would post a scene providing trouble in both V4 XB3-R1 and V4 XB2.1-test2 but renders fine in 3.08
I have a 60 second loop scene which is actually a part of a much larger and more complex animation, it's a tree from forester with a c4d noise shader (for looping purposes) driving a mix material to colour the leaves. The scene will always crash at frame 19, 23 or 24, sometimes providing an out of memory message, sometimes providing the .dll has crashed message and sometimes turning the entire display off.
The system is 2x1080ti's running 398.11 drivers, motherboard bios is updated and card functionality is fine.
I have caught the octane log twice:

Findings
- It will render successfully with no materials.
- It will render successfully with both emission nodes unplugged.
- It will render successfully with the material applied to another object that is not the tree.
- Out of core does not affect the crash.
Seems to not be an issue with the material or the geometry but rather a memory issue of the combination of both. any help would be much appreciated.
Aside from this the AI denoiser is fantastic and overall scenes are much faster for me in V4.
