How to judge TCastleScene touch events

2D
1

Add multiple TCastleScenes to TCastleViewport, click to trigger how to determine which TCastleScene in TCastleViewport. Is there any function to determine? I need to do some event processing for specific TCastleScenes

2

Use MyViewport.TransformUnderMouse.

See examples/viewport_and_scenes/detect_scene_hit README for more possibilities.
