At this time in TG2 there is no indication of which way data is flowing between nodes in the node graph, would it be possible to add arrow heads to the noodles (Lines that connect nodes are called noodles) to indicate the data flow direction; other node based systems most nobility Nuke have them but I have further requirements.
1. Arrow head should only appear in the direction of the data flow in the node graph so the artist may see which way data is going.
2. Arrow head should not appear on noodles on nodes that are not feeding the rest of the node graph and thus are not having an effect on the creation of the scene: this visual feedback system will let the artist know that what they are trying too do is not working.
The above system if implemented in some future release may take a lot of the guess work out of node configuration and save a bit of time and frustration.
