Question about how to change background color

[AuthorityWang]

I wonder how to change the background color from black to white. I try to change the metalKitView.clearColor, but it does not work. When I change the renderer.clearColor to white, all the window becomes white and no item is shown on the screen.

What's more, For the SplatCloud.swift, if we change
descriptor.colorAttachments[0].sourceRGBBlendFactor = .oneMinusDestinationAlpha
descriptor.colorAttachments[0].sourceAlphaBlendFactor = .oneMinusDestinationAlpha
descriptor.colorAttachments[0].destinationRGBBlendFactor = .one
descriptor.colorAttachments[0].destinationAlphaBlendFactor = .one
to
descriptor.colorAttachments[0].sourceRGBBlendFactor = .one
descriptor.colorAttachments[0].destinationRGBBlendFactor = .oneMinusSourceAlpha
descriptor.colorAttachments[0].sourceAlphaBlendFactor = .one
descriptor.colorAttachments[0].destinationAlphaBlendFactor = .oneMinusSourceAlpha
The background color can become white but the gesture to change the camera will be the opposite, and the view to look at the object will become wrong.

I wonder if there is a correct way to change the background color.
