Hi there,
Previously I asked this question on the MC forums, ut as I got no response, I figured why not ask around here.
The problem goes as follows:
I created a custom horse which does the exact same as a normal horse, but with a different layered texture (more layers). Now when I play the game the custom horse loads in fine with texture and stuff, but when I equip it with armor, the armor texture doesnt update until I relog or fly out and in the chunk of the horse.
Anyway, code is located here:
https://github.com/Overreactedosbol/HorsePower
Just navigate to src/main/java/overreacted/horsepower/entity/EntityBaseHorse.class and src/main/java/overreacted/horsepower/entity/RenderBaseHorse.class to see the code.
