In some cases, you may need to install the NVIDIA AI Denoiser (Optix) manually. Here is how to do it:
- Close 3ds Max
- Install Corona by following the standard installation instructions
- Unpack the Corona installer using the "unpack files" option
See the Installing Corona Renderer manually using the "unpack files" option article for step-by-step instructions.
- Once this is done, you should see the folder, where the files were unpacked
- Go to the "Corona" folder and then to the "optix" folder
- Select the .dll file inside the "optix" folder
- Go to C:\Program Files\Corona
- Paste the .dll file into C:\Program Files\Corona\optix
Note: if you cannot find the "optix" folder in C:\Program Files\Corona\ , just create it.
- Start 3ds Max again, and check if the issue is now resolved
