When i apply this rig i have here to my test model. With automatic weights. It totally twists my model. Any clue whats causing this? I tried to mess with the poles rotation. And i tried to apply rotation and scale.. nothings helping.

Picture: enter image description here

Edit: I found out that when i disable the Pole targets it seems to do it right. But how can i make it right with poles enabled?

Turning on Axes for the bones can be really helpful when things twist, and/or before parenting mesh to rig. Like it seems in your case, the twist occurs when you parent mesh to rig with Auto-Weights.

I suspect a complete bone rotation in Y axis in one step, (Y axis is Up for bones)

So probably step 1 can solve it, step 2) 3) are more indepth regarding IK.
