guys anyone know which engine now supports displacement and tessalation mapping much as what this video here shows of the cry engine 2. http://www.youtube.com/watch?v=ON8fU2RWyK4&feature=share correct me if i am wrong, but the cry engine is not freeware open source yet like UDK is right? Which leads me to ask if the other…
I'm not really sure if I understand your question, but for us artists all we need is a height map in the alpha channel of the normal map, the engine / shader does the rest. But yes, you do need a dx11 graphic card.
While on topic - anyone knows of a game engine (or demo environment) letting us play with that ? I think I remember marmoset having the option to toggle parallax on and off, but is it actually fetching the height data somewhere, or is it just guess-timating from the normalmap ?
