I'm a regular Blender user, and my favorite feature of Blender, hands down, is the shader nodes. I can make any kind of texture procedurally and make it look realistic. When I discovered Graphite and saw it had a node editor, I knew I had to try it. After about 30 minutes of playing with it, I feel that in its current state, the node editor is very difficult to use, and that's okay; this is beta software. So here's my primary complaint:
Blender's nodes are very forgiving as far as data types. Plug in a float to a vector3 and it doesn't care. Images are just a stream of vector3s. Just about everything can be translated to everything. Moving to Graphite, it doesn't work that way, and it just feels really difficult as a result. It feels like there's just some kind of trick that I'm missing that would make the system make sense to my brain as Blender's shader nodes did. Thorough documentation on every node will help enormously, but implementing a similar system as Blender would be amazing.
Thank you so much to the developers of Graphite, and I can't wait to see how it grows over the coming years!
