Landscape collision doesn't follow displacement

Hi,
I applied displacement on some of my landscape layers, but my character won’t step up on them anymore.

What’s the problem ? Is there any way to fix this up ?
Thanks

Displacement will not collide, the only thing you can do is offset your displacement so that all of the displacement is happenin below the collission whoch will always be the landscape mesh. This goes for displacement on any mesh/m,aterial.

Thanks for your answer, I did offset my displacement (with One Minus), but then of course, the character is stepping on the air above the lower parts of the displaced material,… which is not so nice either.
Is there any other tool that can help me get the effect I’m looking for ? Or should I just forget about it ?
