The 'yyc' isn't a code problem, so I can't 'implement' a fix. I would like to be able to use the bloom effect. I suggest you implement the fixes of this version since is the latest thing we have until releases an actual full update.
I can open projects with that noyyc fix wereas with the normal 106 (and your community build) I cant because it crashes. David released this fix which solves a lot of those 'fatal errors', it still happens, but less often. The bloom effect is cool, too bad most of my projects crash when im trying to open them since Mineimator is a bit of a mess in the way it manages objects specially when you export/import.
