Not hopeful here, but asking anyway; has anybody figured a way to do IDL rendered scenes with single faced environments? By single faced, I mean rooms and such that are made of one faced planes (can be seen from the front, invisible from behind). Examples would be products like the East Park/West Park stuff over on DAZ. No matter what I do or try to set up, I get MASSIVE light leakage at the seams.There are many products made this way, and I think it's a shame that they aren't usable with IDL, given that SM are promoting it (and hopefully developing it).

I'm using PP 2014, but this isn't a new issue.
