Pick will only work properly with X-Ray OFF!

[C_S]

Hi, some will see this as a problem at 10:21 min:

if using the picker on the “Mirror Object” without X-Ray (ALT + Z) deactivated, it will not work, because the picker “looks through” the object. (For programmers: The raycast ignores the mesh.)

Hope this will help, cheers!

Thanks sounds a useful tip.
Personally I almost never use X-Ray, just solid or full wireframe so I guess I have never come across that as an issue.
