What are those red cubes inside viewport

[madmellow 1]

Hi guys, i stumbled upon a minor question about c4d. I accidentally got these red cubes on some objects in my model and wonder what it is? Seems like a selection group indepent of real hierarchie but i never wanted any group. How get i rid of these selection cubes? I couldnt find any method or button....

Thx

Hard to say without scene, but try to turn off everything one by one. Did you use cloner object? Check it´s transform/display setings if it is not set to weight...

Or if you could ,set scene file without materials...

Have you enabled mesh checker in Attributes Manager, under Modeling settings?
