Hey there,
this is my final node generator node group:
The thing I wanted to point out is that you can also frame redirector nodes only, which I found useful in that you could frame long noodles at the very end and name them after the input pin to still know which input variable is being referenced at the end of the node group tree, somewhat like this:
I was trying to find an easy solution for the problem that we cannot rotate our logs and apply the rotation without our wood generator node logic breaking (e.g. the wood rings would appear on the wrong side of the log), but didnt find anything yet. I think the most easy approach would be to just design your logs upright with the wood generator node, then bake the textures, which is probably how I am going to end up using the node generator anyway, since I plan to export most of my things to unreal sooner or later.
Im off to the next lecture, good luck to you!
Cheers,
Kevin
