Description

Set up this simple graph:

Select the 'Instance Position' node (or instead, wire it up to use the 'Pointer Position' node and select that) then hide it with Ctrl+H (Cmd+H on Mac). This results in a crash.

There are similar cases where this does not crash (these exhibit the behavior we'd expect from the above cases):

  • A 'Vec2 Value' node instead
  • An 'Instance Index' node feeding into the Rotation input of the Transform node

Contributor guide

Research direction
Investigate the crash when hiding Instance Position or Pointer Position nodes. Compare with similar nodes that don't crash. Check if the crash is due to the node's output being used in a certain way or the handle of the node's display. Look for any assertions or unwraps that could fail. The fix may involve handling the case where a node is feeding a value to an input and is hidden.
