Octane CUDA error 101

[grazieromi]

Hi guys i have encountered this problem and don't know how to solve it

Code: Select all

Node type 33 is either unknown, a linker or incompatible to static pin 'groundColor' (P_GROUND_COLOR, type PT_FLOAT) of node 'Environment' (NT_ENV_DAYLIGHT, 000002026E706360)
Tried to access null node pin

Can't read float from static pin 'shutterAlignment' (P_SHUTTER_ALIGNMENT, type PT_ENUM) of node 'OCTANE_BLENDER_ANIMATION_SETTING_NODE' (NT_ANIMATION_SETTINGS, 000002021D6784B0)

The render won't show up in blender but Octane Bench and Standalone it works. I tried to choose 1 of each card in the device preference but both won't work even if they're by themself.

Win 11
RTX 4080 + RTX 2070 SUPER
Octane Blender 27.17
Nvidia Fresh install 537.42 (Studio)

As my thought, review the nodes in your Blender scene, particularly the ones mentioned in the error messages ('Environment',geometry dash lite 'OCTANE_BLENDER_KERNEL_NODE', 'OCTANE_BLENDER_ANIMATION_SETTING_NODE'). Make sure their configurations are correct and compatible with Octane Blender.

Hey man, classic Octane plugin issue.

The good news is since Standalone and Bench work, your GPUs and the main driver install are fine. The problem is 100% the plugin talking to Blender.

99% of the time, it's one of these two things:

Nvidia Driver Mismatch: Your Octane Blender version (27.17) was built for a specific Nvidia driver. Your 537.42 driver is likely too new for it. Check the release notes on the OTOY download page for the recommended driver version and install that one instead.

Corrupted Local DB: Close Blender. Go to C:\Users\[YourUsername]\AppData\Roaming\OctaneBlender\ and rename the localDb folder to localDb_old. Restart Blender and log back into Octane. This fixes a ton of weird render-start issues.

I'd bet it's the driver. Let us know if that sorts it.
