Why do I float on the landscape created in blender?

Hello guys I have created a landscape using ANT . As soon as the character step on it the character collapses. Is it a bug ? Please help…

Double click on the mesh and change collision complexity from default to complex collision as simple

Yes it worked thanks…

Sorry man network problem . Was forced to stay offline for sometime . Yeah surely post . I’ll try to help.
