The Cyclone Game Engine is a cross-platform 2D/3D game engine built upon MonoGame and the XNA Framework to help make it easier and save time creating games. The engine is still in its infancy stages of development. It is primarily built to serve the needs of Steel Cyclone Studios' game projects. More updates are coming so stay tuned!!!
I have successfully converted the XNA 3.1 Real-Time Reflection example to XNA 4.0. You can find the XNA 3.1 original example from the XNA Community Website. This example of real-time reflection was originally created by Canton Javier Ferroro. The reflection of the ship is distorted by the shape of the wood. The technique used is based on making a render with a reflection angle using a clip plane and saving this into a texture for use in the rendering of the scene. This technique is similar to games such as NBA 2K8. I have made the source code available here.
