if the capsule component half hight is < twice the capsule radius the character often falls though uneven floors. I’ve get around this usually by adding collision meshes and custom collisions. but I’m working on something simple where id like to use the capsulecomponant and crouch. but when crouch reduces the capsule hight the characters fall through the floor.
to reproduce:
character collision type pawn set to block world static.
mesh floor collision type world static set to block pawn (block all).
my characters follow a spline only X and Y, set capsule half hight= to radius (round capsule), when character runs on uneven floor (i have an uneven ramp mesh using complex collision as simple) character falls through floor.
set the capsule hight > radius (say radius 45 half hight 92) characters never fall through floor.
like i say i can get around this but its bugged me forever
