hi everyone :

there is something wrong about the SubMesh’s picking

i hava a mesh with two parts, in other words, it has two subgeometries,

when they have the region of intersection, i can’t pick the SubMesh i want to pick .

please help me! thanks !

Hey ggisgg

The behaviour of mouse picking on bounds is controlled globally by the RaycastPicker object set on the view. It takes a global value because the bounds collisions test are much more coarse (and thereore fast) than the triangle collisions test - which can be set per-mesh on the pickingcollider

to enable sorted bounds picking, you just need to add the line:

view.mousePicker = PickingType.RAYCAST_BEST_HIT

That should then ensure the bounds for meshes and submeshes are always sorted correctly
