Cudart64 DLL

[shane_mckenzie]

Getting the missing DLL error for Cudart64.dll.

Using an RTX A4000 with driver version 553.09 on Win 11, Corona 12 Hotfix 2.

There is no Optix folder in the Corona directly as mentioned here:

If I choose Custom in the GPU installer there is no option to select Optix.

Any help appriecated!

Isn’t Corona a CPU ONLY engine? Why would a CUDA driver cause an issue with Corona? I am NOT a Windows expert, just know enough to ask.

You can OPTIX for the interactive de-noiser.

When installing Corona in Custom mode, you should see this item:

No, I didn’t get that option. Gave up and went back to Mac OS.
