Hello! I recently made a solution to tweening an entire model, which was unanchoring all the parts except the primarypart, then using a weldconstraint to weld them to the primarypart, then I can tween the primarypart’s CFrame, and the whole model tweens with it.
However, how does roblox’s physics engine deal with this? Does it freak out in the background trying to calculate what’s going on or is it a decent solution?
Parts welded to another one behave as if they’re anchored, so there’s no “freak out”. There shouldn’t be any concern with the way the physics engine deals with these parts beyond other use cases like querying the part (touches, collisions calculations, so on) - if those are necessary for your system.
