Set Actor Height From Ground

Hey mates.
I have been trying to get a nice collision for a character for prone, and I simply used Set Relative Actor Rotation to rotate the character 90 degrees which seemed OK to me. But the thing is the capsule simply hovers above ground. I used Set Actor Relative/World Rotation nodes to get it to ground but to no effect. It simply refuses to come down.
Any ideas ?
Thanks
P.S: Please ignore the upside down character. It is expected :wink:

Oh hey sorry Iā€™m not helping but asking for advice: How did you make the capsule lay down like that? It seems to only be vertical and only rotate in the Z axis (yaw) when my friend tries to change its pitch or roll to follow terrain.

Use ā€œSet Actor Rotationā€ node in Blueprint.
But let me warn you. Capsule always sticks in the air no matter what I do. I couldnā€™t find a way.
