CPM model with glowing parts having said parts rendered behind everything else.

For some reason, while it worked just fine earlier, now my CPM model with glowing parts have those parts rendered behind every other part of the model. Disabling iris fixes this issue 100%, and I do not know why, but even with shaders disabled it still renders them wrong. Here's a couple screenshots, both of it working with the shaders earlier in the day, and now, where it does not.
