I previously wrote a TileEngine with SFML that I would like to port to Unity3D 4.3, but have not found a way to draw a tile on the screen programmatically in Unity.
All I am looking for something akin to SFML's RenderTexture(), and not a plugin or something from the asset store.
I am using Unity 4.3's new 2D tools/workflow, and as such need a method that will work with the 2d viewport.
