1. Use Sodium/Indium
2. Install a resource pack with emissive texture overlays on entities
3. Entity emissive is not bright/doesn't work
4. Disable Sodium/Indium
5. Entity emissive looks as intended

Expected behavior
The entity's emissive texture should render/be brighter

You did not provide a log file so some guess work had to happen.

I tried to reproduce as best I could with 1.20.6, sodium 0.5.8, indium 1.0.30, ETF 6.0.1, EMF 2.0.2. The drowned emissives were not present, either with or without Sodium.

ETF log shows

Looks like the moremmce file has not been accounted for, that would be an ETF problem, or a problem with the pack itself.

disabled ETF and emissives still don't work so this mod is not the issue, tested pack and it works without embeddium 0.3.19/sodium 0.5.8 present, and it doesn't when it is.

no sodium

sodium enabled

Log when Embeddium 0.3.19 is enabled (sorry for resource pack test bloat)

Ok I thought you were using ETF to add emissives, but the critical step is using moremcmeta-emissives. This mod requires Indium to be compatible with Sodium. See their readme: https://modrinth.com/mod/moremcmeta-emissive

My bad for not using Indium for logging the mod, however I have been using indium previously with the same results, moreover embeddium has native fabric API rendering support so indium is not needed.

The changes required to update the plugin for 1.21 have also fixed this issue for Sodium. These changes are quite substantial--it would likely take a lot of work to backport to 1.20.6 and other versions. That takes away time from me being able to investigate other mod issues. For now, I am planning to fix this in 1.21 and later versions only. I will update this issue if that changes, but I am closing it as I consider the issue fixed.

Please reopen or create a new issue if you still see this on 1.21+ versions.
