tessellation problem

Hello I was trying to create a tessellate material but even though I’m setting all the nodes shown in the documentation I can’t get it right. Here my material, texture and result

as you can see from the pictures, the result is not smooth at all, I also tried to use a texture with only the stones and the ground with alpha(instead of white) but the result is basically the same.

Any idea?

Thanks

I’m certainly no expert, but I’m guessing you need a normal map to get the correct surface normals on your object after its displaced. I don’t think the shaders in unreal recalculates normal values after displace like your offline renderers do (like arnold). Please correct me if I’m wrong!

I tried to add a normal map and the effect persist, so I suppose the problem wasn’t there, but thank you for the tip.
