Tried to make a guide book with patchouli for my modpack.
But it has a issue with showing the mobs properly.

Steps to Reproduce:

I was using Geckolib for my animations.
Had to add this to solve it...dont know if it will help.

@OverRide
public RenderType getRenderType(T animatable, float partialTicks, MatrixStack stack, @nullable IRenderTypeBuffer renderTypeBuffer, @nullable IVertexBuilder vertexBuilder, int packedLightIn, ResourceLocation textureLocation) {
return RenderType.entityTranslucent(getTextureLocation(animatable));
}
