Hello to everyone!
I'm doing a translation of https://github.com/ZaneDubya/UltimaXNA to MonoGame because this one has a lot of new features (as DirectX and OpenGL support) directly in C# and because XNA is Dead.
However all is working fine but i've a issue about Hue managerment.
This is the pixelshader effect that works with XNA but i've translated it to MonoGame, the language used is HSLS and i'm not good at it.
I had to comment the hue color part because it brought each hued color to BLACK #FF000 . Could you help me to solve this issue?
I think that if i can make it refer to UDK, it could be great to have a game who supports even new formats ^^.
Maybe you could be interested to lend me an hand about it ^^.
