Maintain Collision of Bodies in Lyra?

Hello Xist,
Let me ask you the same question, please (seems Romance is not active here any longer):
In Lyra game if I set collision to “Block all” (following Romance idea) my character cannot pickup weapons/health. I would appreciate if you suggest how to modify Lyra to make “dead” NPCs to interact with environment (e.g. be tossed if you run into them), but yet for the player be able to interact too.
Thank you!
