Soft body edges in 2.78a I've got a hand model, I've rigged it and now I'm trying to avoid the fingers passing through the hand itself. 

I understand that to activate Self Collision in Soft Body I have to activate "Soft Body Edges" but I simply can't find it in Blender 2.78a. When I select the mesh, and go to physics, there is no option for it like in previous versions.

How can I make it?

Thanks!

Edit: I've seen that there might be a problem with the model that I have imported. It's this one http://www.blendswap.com/blends/view/81285 and the one used is .x3d. It's a ShapeIndexedFaceSet
REWRITTEN ANSWER: Based on your screenshot, you must be in "Blender Game" mode. The settings you are looking for are available only if you use Cycles or "Blender Render".
