How do i make meshes look connected?

Explain more, nobody understands a thing

Sorry, You see the line in-between the two red meshes, Is it phyiscally possible to remove it or make it less visible, These are two split up meshes.

Not through Roblox itself I think, you’d need to import it into something like Blender. Group it, change the vertices/fill them. Shade smooth, auto smooth maybe, it depends on multiple things.

Looks like a texture issue to me, but they could also not be the exact size

How do you recommend i make them the right size as neither have any textures

Well, first of all you can copy the same mesh in blender, then just change the shape of it instead of remaking a new one with different sizes

If you shade smoothed them, roblox lightning will also effect it so it looks like that, instead of shade smoothing, you can use more bevels, otherwise use a light map
