frame buffer scripting support for changing background

[sentry66]

This is really minor, but probably easy to implement. Just wondering when we'll be able to change the background image of a render in the frame buffer via scripting? We used to be able to do that with the old frame buffer

You still can, but it's a bit different. This is a sample script to create a Background layer:

vray vfbControl -createLayer "chaos.ref.external" 1

An ID number will be returned for that layer. To change the background layer's image:

vray vfbControl -layer <id> image "path"

If the background layer is already created you would need to get its id first. With this:

vray vfbControl -findLayersByClass "chaos.ref.external"

You can list all available classes like so:

vray vfbControl -listLayerClasses
