The Unreal Tournament SDK is a collection of hardcoded Engine Enhancements for Unreal Tournament that aim to update that wonderful old game so that both gamers and level designers/mod developers may enjoy this fine game just a bit longer. It is completely Open Source, free for noncommercial use. While I know that Unreal Engine 4 is the current state of the art incarnation of the Unreal Engine this project has become a more or less private project just for fun. After a 4 year break (coding nothing since 2014) I'm lookng forward to continue the project and release the next update in 2018. So yes... it's active again, after I had a time of hardship these last years.
The Unreal Enigma Particle Engine now supports smooth dynamic Color Transitions between up to 8 colors. There'e different transition types and the transition depends on time.
Emitter to the left: Transition goes from red (gold) to green
Emitter to the right: Transition goes from blue (cyan) to green
The transition time used here was 3 seconds.
