Trying to render with Optix:GPU on an RTX 3070 Ti gives nothing but failed renders. After a few seconds of 'Loading render kernals' it briefly flashes what seems to say a COMPILE_ERROR but it doesn't output this to the Log screen so it's difficult to give the full version of the error code. It even fails to render a basic scene consisting of only the Construct and one of the default Poser Superfly Lights sets. No figures or shapes. Odd thing is, it worked once or twice after installing the latest version, even on more complex scenes, but for whatever reason it hasn't since. Clearing the Optix cache in Appdata\Nvidia hasn't changed anything.

Non-Optix GPU renders work fine.
