Oh my god I'm so sorry I haven't seen your comments here. Definitely not abandoned. I've had some personal issues over the past months and had to take a bit of a longer break from my vfx assets. The issue here is that the color/emission values are going into the negatives ( I think) which I didn't notice when making this.
A temporary fix would be to in the shaders add ALBEDO = min(ALBEDO, vec3(0.0)) at the bottom of the fragment shader
