Hi Todd, I can't say why your are having problems with transparency in 2.8.1 vs 2.4, as depth sorted/transparent bin hasn't changed between these versions. Perhaps a subtle difference in the loader has caused the difference, or perhaps there is something undefined in your data that the two versions behavior differently with. It's a bit of a case of hunting for a needle in a hay stack so you'll need to try and isolate the different possibilities.
Try converting your data to .osg and see if the two different versions behave differently with this, even bettern convert the .ive to .osg using 2.4, then do the same with 2.8.1 and then have a look at the differences, if they are effectively the same then go have a look .osg file to make sure that the objects that you think are transparent are correctly assigned, and also check to see if all the geometries have vertex, normal and colour arrays as required by the state setup in your scene graph.
