Rendering using RT / VRay Standalone fails

[lcrivell]

Hi,
I try to render a vrscene using the -rtEngine=3 flag (OpenCL for me) and get an error (see in red below). Does that mean I have not a compatible GPU ?
I am on a Mac.

Thanks.

Mac can't compile our OpenCL code currently. Use other OS, or NVIDIA card with CUDA.
