How should material tesselation work?

Tesselation multiplier limited to 1. If you limit it to 2 you only increase the distance you can see tesselation

Hello,

That is expected behavior. The tessellation strength value uses a float up to 1 to subdivide the mesh, but allows the amount to go further so that it is tessellated at greater LODs. This limit used to be 8, but was reduced for performance reasons as described here:
