Well, I was trying to render it dynamically at first, by using vertexes, WorldRenderer, and the Tessellator to draw the texture of a block. But then I noticed that I had the IBakedModel of the Block I wanted to render as, so I thought that would be easier to use, especially if the block used multiple textures (furnace, grass, etc.). If there is an easier way to accomplish the same thing without using a TESR, please let me know.
