		pmoursnvUnsubmitted Done Inline Actions This is the reason you see `OPTIX_ERROR_INVALID_PTX`. You are compiling the CUDA kernel with `cycles_cubin_cc` here, not the OptiX kernel. Changing this to `-i ${CMAKE_CURRENT_SOURCE_DIR}/${input}` fixes that. It unearths some other problems though: OptiX needs C++11 in kernel code, so `cycles_cubin_cc` has to add the `--std=c++11` argument to NVRTC. The OptiX headers include standard headers (`optix_7_types.h` includes `stddef.h`), which are not available in `cycles_cubin_cc`. pmoursnv: This is the reason you see `OPTIX_ERROR_INVALID_PTX`. You are compiling the CUDA kernel with…
