Hello everyone!

In this example, I’m trying to get the correct faceId by clicking inside the mesh using the clipped plane.

In this screenshot, I click inside the cube, and I get the wrong faceId.

This screenshot shows the faceId that I would like to get.

How can I do it?

This is not supported at the moment ☹ clip planes are only a rendering feature.

I wonder if in this case you could not ray cast from the opposite direction ?

I have a large building mesh. With clipped plane I cut it in half. I need to select one of the faces inside the building with a click.

the workaround would be to raycast to the clip plane first and set the clip plane intersection point as the start of the ray ???
