Making static entities collide with player

[Exostalker]

So I made new static rocks, because I needed them to not collide with each other (otherwise if I put one rock inside the other, they jump out). But now player can go through all of them without colliding. Here are the parameters of the rock entities:


----------------
mass 0 (if I change it, nothing changes)
angular damping, linear damping, max angular speed, max linear speed - all 0
density mul 1

and here are the checked options:

countinous collision
collide character
use surface elements
has gravity

if I check all of the options, nothing changes as well.

in user defined variables it's set to type object subtype static.

please help!
