This free application allows you to load a 3DS or X model for quick viewing in a real time DirectX based window, once loaded you can rotate and move the camera to view your model from any angle, play any model animations, change the texture and try out different shaders. All this can be done quickly and without the need to load a full game engine to check the model's appearance in a game environment. Features include: Loading of 3DS and X model formats. Replace your UV mapped textures in real time - no need to reload it. Use built in shaders, Bump, Normal, Coloured Glass and Reflection. Load your own FX shaders to apply them in real time. Replace your shader maps in real time. Play a models animation and rotate around it whilst it plays. Loading and saving of scene setups. Back face culling display. ModelFX is still under development, all feedback, suggestions and comments are appreciated and will be taken into consideration with the next build. The loading of new textures and shader maps is most usefull for quickly trying out different effects without changing the original model, the texture and shader maps loaded in real time are not saved to the original model, but are saved to the scene setup.
