Describe the issue
While testing an ETF skin I was making for someone, I found that when using the 3d Skin Layers mod, emissive player skins aren't emissive on the 3d layers (i.e. the outer layer)
I have also submitted an issue on the 3d Skin Layers Github

Screenshots
(I'm using shaders because it makes the emissive textures more visible)

Without 3d Skin Layers

Your setup: (please complete the following information):

• Minecraft version: 1.19.2
• ModLoader: Fabric
• ETF Version: 4.2.0
• Does the issue persist with only ETF installed?
  No, as the issue is caused by the mod
• Have you checked the FAQ in the Readme, or Discord, to see if it is a known issue?
  Yes

This is a known incompatibility, it would take a lot of work to make compatible, so will remain incompatible for a while if not always :(

Dev build in my discord with the first pass of the fix for fabric

this has been resolved in release 4.3 https://github.com/Traben-0/Entity_Texture_Features/releases/tag/v4.3.0
