It be great if the TOPto CHOP
1: had an on/off toggle (or sample “trigger” button), as locking/unlocking seens to be an expensive operation.
2: could sample at multiple defined uv locations, i.e. give it a list of uv locations and get 1 sample per uv entry in the CHOP channel. Very needed for multitouch panels which are created by rendering a 3d scenes, so you don’t need 10 expensive TOPto CHOPs to get some custom renderpicking working.
