Question by Ogdy · Jul 04, 2017 at 11:52 AM · editor raycast colliders selection

How is mouse picking (for selecting) working in the Editor ?

Hello,

I have a scene with several meshes generated during runtime. I want to be able to do basic mouse picking (clicking on a mesh to select it).

I've done it the "normal way" until now, adding a mesh collider and assigning to it the mesh used for representation. However, this operations takes a lot of CPU time with large meshes.

I noticed that the mouse picking in the editor works even if no collider is attached. It even works with my runtime generated meshes.

Do someone knows how it works in the Unity Editor ?
