描述

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

研究方向
The crash occurs when hiding a specific type of node (Instance Position or Pointer Position) that is feeding a value. Investigate the code handling node visibility (hiding/unhiding) and the node evaluation pipeline. Look for differences between the crashing nodes and similar non crashing nodes like Vec2 Value or Instance Index. Check for potential null pointer dereferences or incorrect assumptions about node output types in the hiding logic.
