Hello! I’m Mateh, and I’ve hit a bad problem which makes my game lag a little more and my explorer look less organized. It is actually a very issue, however I have no idea how I would fix it.
This is one of 50 stone walls on my lobby. I have no idea how I would mesh/union them all together. Thank you in advantage!
P.S Don’t spoonfeed me if possible 
@Dev_Mathe
All I need is to somehow union them all. Please note that they are meshparts!
The other parts of the map dont look so much detailed, so using a texture might be a better choice. Otherwise, no idea why this would make your game laggy, check if you anchored the mesh parts.
But if you are still looking for a answer to your first question;
go to blender or whatever 3d modeling software you are using and just copy paste the object, then move it along the axis as if you would copy paste the walls in roblox studio.
Hope this helps!
Please don’t try to combine all those meshes. If the game can’t handle all those triangles in all those meshes, I doubt combining them into a single instance would stop the lag, let alone Roblox allowing you to import meshes of a really high triangle size.
If I’m correct, your using the low poly wall from the Roblox-provided mesh pack, but looking at your picture your game does not look to have a low poly aesthetic (you are using materials). Because of this, you should instead upload a PBR material and use that, or if you want to stay simple you can just upload a single brick texture.
It’s impossible to union meshparts, so the best solution is to import it into a 3D modeling program so you can form it all into one mesh.
@CriticalDucky’s solution is better than mine. A texture looks like the best idea here.
