Crocodilum Hello! Before, I was always going back to the setup mode to modify any mesh weight. But recently, I just did it into the animation mode, and everything went fine. Is that a good practice? Of course, I know that for every vertex that I change, if I already have several animations, it might break some serious parts. I was just wondering if changing the weight into the animation mode is okay, or if it's better to stay in the setup mode to do such modifications.
