Is there a way to just select all Vrayproxies (which are missing path) in the opened scene?
Sometimes, empty VRayproxy causes crashing error in 3ds Max when rendering with MultiScatters, and they're nowhere to be found on projects folders. So it's easier to just select all of them, manually check those missing/empty VrayProxies and delete from the scene.
There's old script called Vrayproxies Manager in here but it's too old, >10 years ago and no longer works, the interface looks neat though (scriptspot.com/3ds-max/scripts/vrayproxies-manager)
