Hello, you are trying to render with POV-Ray… and you haven’t installed it yet on your machine. So you can do one of (at least) two things: just chose another renderer from the rolldown, or install it and it should be autodetected from registry keys. If it is not, the addon preferences have a field where you can manually specify the pvengine64.exe binary path.

You wrong. He says he is trying to install the addon. Not trying to use it.

I get this when trying to installl an addon. Its for blender 2.91, Does this mean the addon needs to be updated

Googling “BYASP,” clicking on the first link, then clicking on the only Issue, lead me here:
