I’ve been working for a lot of large groups and they expressed how lag comes from unions and to use mesh instead. It’s been a bit more difficult without unions.
Also, if you convert things like chairs made out of parts into a mesh, will that actually reduce lag? I’m talking about like having 100 chairs in a building, with each chair taking up like 10 parts. Using mesh wouldn’t that reduce it to a 100?
Recently also found out I can export a union as an .obj then bring it back in as a mesh. I was wondering if this is a solution which works. Personally I think it does but I was wondering if anyone knows more about it.
I think this could help you. This is an official roblox conference so you should keep it very much in mind.
I don’t think this will work. One reason is that when you use meshes for performance reasons, these meshes should be LowPoly, that is, with the minimum number of triangles possible. But if you simply convert a union into a mesh you are not reducing the number of triangles, so it will have no effect.
If you export a Union into Blender many times you’ll notice there are many more tris than required.
I typically make a basic Union in Studio, then export it, clean it up, then bring it back as a mesh.
