Whenever I take single parts from the toolbox, whether thats a kill brick or a stud brick or anything else - I find a weld inside of it. Why? It’s a single part and I don’t think it’s welded to anything else. Does it make the part weight more?
In addition, I’d also like to ask what makes an object weight more?
Disable JoinSurfaces in the home tab.
What makes an object weigh more is because of its mass. You can change this in the CustomPhysicalProperties in the Properties tab.
Coming back to this topic to specify, whenever I take for example - a stud brick from the toolbox, I find a weld inside of it. Why is that?
As @cheesy_roblox190 specified… the person who uploaded the brick had their JoinSurfaces enabled, so whatever part they uploaded had the weld automatically placed inside of it when it was created.
