Why is the emissive textures so dim?

[Arclightning7]

My emissive texture packs are extremely dim on Mcmeta compared to optifine and I'm trying to figure out why.
Emissive

Non-emissive

I am using Forge 1.20.1. I have the standard performance mods such as rubidium, ferrite core and modernfix. I did look at the other thread where someone didn't have them show up due to modernfix dynamic resources, but my issue is that the emissive textures are extremely dim, not that they don't render.

As it would turn out, the issue was Rubidium.

Yes, this is a known issue with Rubidium and would need to be fixed on their side: MoreMcmeta/emissive-plugin#2

Someone says that it was already fixed--perhaps just a Rubidium version update is needed?
