Only problem with screens is that they become a lot of work for environment packs with large mesh counts. Checking the collision should be, and as far as I’m aware is, part of the marketplace evaluation process. We shouldn’t administer one size fits all solutions for small, isolated problems that aren’t widespread. Saddling content creators with an over complicated submission process and product detailing will lead to fewer participants. I personally don’t feel the right solution is to punish all for the actions of very few.
