PROBLEM: when trying to shrink objects that I built, (at the moment a mix of 2 Unions an 2 parts if it helps) it done’t but it just mucks up the tool by moving bits to random positions near by.
I HAVE TRIED: Turning All unions into the base part which works but is anoying and can muck up my model.
The random jitter on the parts is the cause of float-point errors, where the number is “rounded” to something computable. Usually this is because of limitations and it is far noticeable in far distances from the center of the workspace.
You haven’t explained exactly what the shrinking was intended for.
Gun models in Roblox of higher quality are usually made out of meshes or unions. You cannot have smaller BaseParts than 0.05 in all axis. Therefore you should either learn solid modeling by pretending that you’re sculpturing a gun in Roblox or learn Blender.
