"Hidden" node's attribute make node transparent (1.3.0b8)
- Open a RenderGraph.
- Create a Surface node or a Attribute node.
- Activate "Hidden" in the "Primitive" section.
- Go outside the RenderGraph.
- Open the RenderGraph again.
- The node is transparent.
I guess the UI check a "Hidden" property of a node and display it accordingly.
I suggest you "protect" your internal node's attribute (one or two underscores in the atrtribute name?). This would avoid such "intersections".
