FeiHongJr, your script worked perfectly. I am able to load my level (in 6.3) and move the camera angle around. Thank you very much for that! 6.4 still won't load, due to the entity-limit problem, but I plan to open a small test level and look at my trees in that.

I did actually open one of Loopix's trees in my small test level, with DabroOzar's script assigned to it, and though the tree came up with the alpha working, the sorting still looked odd. I'm going to try this again after work today and see if I can get the script running with my own models, and then compare scripts to see what sorting differences there are between them.

Going on someone else's suggestion, does anyone know how I could simply and quickly take one of my own models and have it automatically broken down into many smaller parts (and retain skin & alpha info) so that I could try fixing the sorting issues that way?
