[meierdesigns]

Hey guys I got a problem, while baking a AO pass in octane within blender.
it normally works but not with this mesh:

I got this log:

Tried to access pin via an invalid ID P_RENDER_PASS_REFRACTION (185)
Tried to access null node pin
We can't evaluate items of a different version (version 0)!
Tried to access pin via an invalid ID P_UNKNOWN (0)
Tried to access null node pin
Can't read bool from static pin 'unknown' (P_UNKNOWN, type PT_UNKNOWN) of node '' (NT_UNKNOWN, 00007FF9BE8AE230)
CUDA error 700 on device 0: an illegal memory access was encountered
-> failed to create link
device 0: failed to create OSL compile context:

device 0: failed to compile module 0

Any idea what to do?

best regards and thanks...
