Hello everyone!

I'm creating a voxel game in Unity (sth. like Minecraft), and i've got a serious problem: There's no collision with backfaces (back, left and bottom block faces do not have collision). I've already tried switching all normals to positive or replacing left face with right face - 1.I think that Unity or physics engine recalculates normals somewhere, what makes backfaces come back.

PLEASE! Help me, my project is stopped for this reason and i've no idea!

No idea about Unity specifically ... but it sounds like your vertex order is wrong for some faces. They should all be counter clock wise (which is the usual default for front face).
