Natural Mod for Crysis

The “Natural Mod for Crysis” is an amateur project I carried out at the end of 2007, shortly after the release of Crysis for PC. I completely redesigned the lighting for the singleplayer campaign using the CryEngine 2 Sandbox Editor.


The objective was to provide a photo-realistic lighting based on photo references. It made a better use of HDR, atmospheric effects, exposure and colour correction than the original game.

I shared the modification in December 2007 and I kept iterating on the lighting with new improvements and refinements for several months. It became quickly successful, with +350’000 downloads as of 2013. Thanks to this modification, Crytek offered me a position at their headquarters in Frankfurt, Germany.
