When I use the Attribute Blur node in H18 I get this: “Error: OpenCL Exception: clBuildProgram (-43)..”
This doesn't occur in H17.

One solution I saw (which doesn't work) was to modify the env file to: ”HOUDINI_OCL_DEVICETYPE=GPU“.

I'm on an olde Mac 2013 dustbin, I saw someone suggest older macs may just be stuck with this error.

Thanks

Bump…
No one know?
