Question on LOS tile properties

[clownagent]

Is there any possibility to make a map-tile that blocks line of sight to units, but does not blockade walking through and shooting through?
It could represent some kind of very thick fog or an 'illusion' tile.

I tried to switch the LOS mcd (no 31), but it does not block line of sight to units, only terrain. This I find strange, but is apparently the intended behavior:

If I use LOFTs, walking through is possible, but of course not shooting through.

I like your idea, that would work good as an energy shield or something similar.

Maybe... What if you use an edited door mcd-entry? Make it have no animation(or give it a static one), that way it would also seem to cost some effort (TUs) to walk through the shield barrier.... Not sure if it will work....

this really is a tricky question!
