Note: I've never used the world editor until now. I've not found any tutorials that seem to make sense to me; I've only gotten this far, randomly clicking buttons. I've got some Alpha issues on a track I'm trying to create. I've managed to jam a DAE into a file, and just want to use it as a reference for when I add lower-poly parts. BUT, the material is doing weird alpha things I can't seem to figure out. Often the material editor glitches and crashes, so that's not helping either.

Looks a bit like it has some sort of odd alpha property applied. Try looking at the advanced properties in the material window for that material. Might work. Something is definitely up anyway.
