Hello, I would really like to avoid any form of core modding or vanilla file replacement.

I have got this but entity models are not possible to modify in this way after registration. Either way here is my attempt:

@SubscribeEvent
    public static void renderPlayer(RenderPlayerEvent.Pre event) {

        PlayerEntity player = event.getPlayer();

       PlayerModel<AbstractClientPlayerEntity> model = event.getRenderer().getEntityModel();

        if (player.getCapability(VoidProvider.VOID, null).isPresent()) {

            IVoid cap = player.getCapability(VoidProvider.VOID, null).orElse(null);

            if (player.getActiveItemStack().getItem() instanceof ItemCasting && cap.getMaxCharge() > 0) {
                ModelRenderer arm = model.bipedRightArm;;

                arm.rotateAngleY = -0.6F;
            }
        }
    }

I think you don't need to replace vanilla files.  View this topic.
