I tried to make a forcefield block using a filemesh for giving it a texture.I tried to edit the size but I’m not able to do it.When I tried to edit the size,the hitbox around the filemesh changed size but the filemesh didn’t
Filemeshes seem to be pretty unreliable, so I’d try using a meshpart instead and insert a texture onto each face - slightly long way around it but it’s worked well for me.
So if i turn it into a meshpart i can still put a decal’s texture?
Yes, if you import the mesh file (.obj or .fbx) into the meshpart you should be able to insert a texture onto each face. You could also download the beta version of studio and use a surfaceappearance which allows you to cover the entire object in one texture, rather than manually applying it to each face.
Everything above is correct, but just to answer your actual question - to resize a Special mesh, FileMesh or any other Mesh object in a Part (that isn’t a MeshPart), the scaling properties are in the Properties window.
