Hi,

Rather than a list of dedicated RTT objects which will never cover all the diferent use cases, I think this is better to re-use the camera class with it's subgraph, which already works well : by building different small sub-graph we can implement different processing (with a render quad as input, or with a point cloud, or with anything else).
