I've been partly out of commission for a while. It's taken me too long to get this fix up. What it is is improve transparency by sorting triangles. I may've already uploaded something like this, but it turned out to take a toll on the performance, so I had to innovate a little bit. In the meantime I noticed the current upload had messed up the double doors animation, and maybe some others, that are now fixed.

I've reverted back to the pure donation model for this demo for now. I'm sorry, I was going through some "unbelievable" stuff when I changed it.
