sorry it took a bit to respond!
- When trying to change the size of the help panel (using slider to make it thinner) my display panel went blank. I tried fitting width and height but nothing is visible. Tried adding a new shader, new shader is now the only one visible, seems to have overwritten everything else? (I save scenes frequently so I can figure out what I was doing though :))
That sounds like a bug I haven't run into yet! I'll see if I can recreate it and get that figured out.
- Is there an undo button?
At the moment no, but it's something that is half implemented, so hopefully undo/redo will come soon.
- From a novice perspective (which may not be the intended user), it may be helpful to provide some example scenes that users can load to get an idea of how to approach shader interactions, inputs, etc.
That's a good idea, maybe an 'examples' menu in the toolbar. Is there any particular part of camogen that felt hard to use?
