You can set your blocks to none :
select yout block->right click->properties->
surface->click flags->click None.
Compile and run, now your block is invisible and
not passable.
You can do this, but the block will still cast a shadow if a light source hits it; thus shadows from nothing. Before c_instructions, you could create collision geometry with invisible blocks(which don't cast shadows), but you now have to make them invisible map entities.
