P2 - fixedRotation causing troubles

[t-w-in]

Hello, can you please help me?

I require non-rotating crates. Like in this oficial example: http://phaser.io/examples/v2/p2-physics/platformer-material , where I add just one line box.body.fixedRotation = true; to the for cycle creating the boxes.

Suddenly, they start to shift and slip. I need them to stay still. 

How can I fix this? Do you have any idea please? I would be very greatful! I have tried using different materials, but notning helps. Friction is just gone

Hi, I'm still struggling with the issue. Do you have any idea, please?

I played around with the example a bit, and it seems to be caused by box/box friction. So you could try this:

var boxBoxCM = game.physics.p2.createContactMaterial(boxMaterial, boxMaterial, { friction: 0 });
