Hi BradLarson, i am trying to init a renderView by code like let device = MTLCreateSystemDefaultDevice() renderView = RenderView.init(frame: self.view.bounds, device: device)but it doesn't work, doesn't show the camera. Can u help me? THX

Ah, I think we forgot something there. The RenderView should be using the sharedMetalRenderingDevice.device Metal device, but it allows you to override that. For now, I've committed a change that will override any input device, so you should be able to provide nil for a device and not worry about it.

Otherwise, you can use sharedMetalRenderingDevice.device for that parameter to make sure it uses the same device as the rest of the framework.
