Hi, the name could have been anything, "helper node" was just an example.
I am afraid I did not understand the concept behind helper nodes. I thought they are some "symbolic" nodes only for grouping other nodes, so they do not need to contain data. According to your mail I was wrong. But if they contain data like other nodes then what is the difference between helper and not helper nodes? Nothing? Is this only a flag? What I need is some nodes for grouping other nodes, but not containing data. Just for organizing the image nodes. Is there a way to achieve this? Shall I create a "fake" image (0x0 pixel) and assign it to such nodes?
