We are going to see how to add a simple render of your CraftStudio model to an entity.

You'll need to create a simple entity, we aren't going to see the complete process here, to gain time, but you can find good tuturial online.

Go to the render class of your entity:

public class RenderTest<T extends EntityTest> extends RenderLiving<T>
{
    public RenderTest(RenderManager manager) {
        super(manager, new ModelCraftStudio(ModTutorial.MODID, "my_model", 64, 32), 0.5F);
    }
}

As you can see, we just need to replace ModelBase by ModelCraftStudio.

The API load your registered resources before the game pre-init to create the 3D render in Minecraft.

We must give some parameters to the constructor of ModelCraftStudio.

new ModelCraftStudio(modidIn, resourceIn, textureWidth, textureHeight);

modidIn is the id of your mod, resourceIn is the name of your 3D model previously registered, textureWidth and textureHeight are the width and heigth of your texture.

Tip: If the texture is a square, width is the same as height, you can use the function:

new ModelCraftStudio(modidIn, resourceIn, textureWidthAndHeigth);

Exemple:

new ModelCraftStudio(ModTutorial.MODID, "my_model", 64);

And Voilà ! You now have added your CraftStudio model to your entity !

If you want to animate it, it's here!
