Element Number Limit

Is there a limit in number of Elements in a Skeletal Mesh, and if so, how many max?

I’m assuming by elements you mean number of bones/weights.

You can have 65536 bone indices.

Maximum (default setting) 255 bones per mesh.

Maximum 8 bone weights per vertex.

No limits on maximum vertices.

see this answer for details.

I’m sorry I failed to ask clearly. In mesh window, there are (sometimes) multiple elements and each element is a material. I asked those elements’ number limit.

If I understood you correctly then according to this thread, the hard limit is 64, which is limited by the fbx importer. But remember that each material adds another shader call which may limit your performance.

Great, thanks!
