after yesterday spending the whole day doing proper calculations for the cloak system i came to some conclusions that i modelled and rendered with the most rigorous process possible and it works perfectly! the walls are all gone and we see straight through them!
heres the first page of the summary. I am preparing another one with more complex systems that erase columns for more than 2 points of view!
more to come soon!
UPDATE: new spreads with tests for column systems
