When using a Optifine CEM replacement for horses with random variants using EMF, ETF appears to be trying to use the unmodified horse texture files; the models render the correct texture (including variants), but emissive textures don't load.

This is the output from the debug log:

[08/10/2023 20:14:04 PM]  - Texture: ETFTexture{texture=minecraft:textures/entity/horse/horse_white.png, emissive=false, patched=false}
[08/10/2023 20:14:04 PM] Entity cache size: 134
[08/10/2023 20:14:04 PM]  - Original spawn state: null
[08/10/2023 20:14:04 PM]  - OptiFine property count: 0

• Minecraft version: 1.20.1
• ModLoader: Fabric
• ETF Version 4.5.1
• EMF 1.0.2

should be fixed in emf 1.2 and further stabilised with the next update not yet released
