I was doing some shenanigans in studio trying to play around with physics and stuffs and found out this weird bug.
I was expecting the builds to anchor themselves, or at least stay welded (and keep positions) while moving but it doesn’t. Constraints are hurt the most. They don’t even go back to their original place like classic welds do.
Where - Studio When - Starts when you move welded parts in studio using the Move tool.
Repro
Open studio and go on a blank baseplate.
Use my model: Weld Glitch - Roblox
Drag it up and wait a second. You will see that physics will happen even though it’s welded.
Could you please post a video that demonstrates the incorrect behavior?
Weld Constraints ensure the relative positions/orientations of bodies are fixed. When you drag a body that is welded to another body, the position/orientation offset between the bodies is updated.
