Does deleting a union, then uploading that union as a meshpart instead back into roblox save performance or no? I have no idea why ppl say this because I think it just uses the same geometry from the original union so there wouldnt be any performance changes but idk
depends, unions tend to have bad geometry but uploading them as meshes can help with filesize of the .rbxm place and load time?

Unless you’re removing extra vertices/faces - yes
union’s problem mainly comes from the complicated geometry it has, basically zero optimization whatsoever
Unions are CSG(Constructive Solid Geometry)
As I know Unions will save datas of every shapes included in it. But Meshes will contain only vertice datas.
