Fireflies Invade Morrowind glowmap weirdness

[medlirezor]

It's not hosted here but this mod has been presenting me with graphical glitches, which I suspect is due to the use of MGE XE, and it happens with and without shaders. The mod is found here, but can also be found on mw.modhistory.com, and seem to be the same exact file (did not compare hashes). https://firefly.calislahn.com/

There's a bit of a glowy halo made of three planes built into most of the firefly models that cycles through a series of glowmap textures, built directly into the NIF. They render strangely as the textures look blown out and one can easily see the edges of the planes as a square with the nonemissive bits of the glowmap showing as a sort of grey rather than the expected transparency. From what I can tell in prodding around in the CS, on spawning the fireflies attach a light to themselves, and my observation shows that the ones with the strongest lightsources are the glitchiest, making the glowmap planes a solid white.

Could somebody please help me understand what's going wrong and how I might go about fixing it? I've already tried removing the attached lights to no improvement and I tried ripping the glowmapped planes out. I gave that a hacky test run but it seems that they really need that glowmapped halo effect to be all that visible from any kind of distance.

This happens to the fireflies with any MSWE 2.1 later than the September 2020 release. The fireflies display the semi-opaque squares with little or no green lighting.

 

I don't update either the MSWE or MGE XE because this firefly mod is a must have in my load order.

 

Users of OpenMW report the same thing and apparently, if I understand the thread correctly, it is fixed for those who use OpenMW.

I would try to use the fix for regular Morrowind with MGE XE but this is beyond my understanding.
