How can i fix the clipping in my game?

Hiya,
I’m currently working on a map, and using a master material for the landscape ( Landscape Auto Material, from UE4 marketplace). The material has tessellation enabled, and in wire frame mode, it seems it’s working, but whenever i hit play and run up the side of a hill, the character sinks into the added geometry as shown here

I tried to add sockets to the feet, and add collision to those sockets, but that doesn’t seem to work.

s there any way i can add collisions to the rocks/pebbles that are all through the level?
If it was just an art piece then i wouldn’t be so worried, but i bought the material for use in games and if left as is, it would be a pretty terrible experience.

Someone please tell me what i can do to fix this, i know plenty of other games that seem to be using tessellation in landscape material, and they don’t have this issue.

What am i missing?

The collisions are what is generated for the landscape, and the rocks are a material with tessellation enabled. They would otherwise be a flat texture, I also tried to raise character mesh but then his feet are off the ground when he’s on a flat surface.

Is it possible to force the landscape to add the displacement to the actual landscape?
So far it seems that the landscape collision does not match the displacement.

I’m still fairly new to level design and materials, most of my time with UE4 so far has been learning the C++ API. Now working on visuals, and it seems more complicated than the code…

Make more precise collisions on the rocks. As a doubtful option - increase height your characters capsule and slightly raise the char mesh inside capsule.
