Download Hilva XNA Engine v1.8 for XNA 4.0 Beta.

What’s New:
- The library has ported to XNA Game Studio 4.0 Beta. Most shaders re-compiled and optimized for this version of XNA Framework.
- A new post process effect, HSL, added to the library to add support for Hue-Saturation-Lightness manipulation of the output frame and/or any other texture.

Changes:
- Hilva.Graphics.Materials.dll and Hilva.Graphics.PostProcess.dll assemblies are merged. The new assembly’s name is Hilva.Graphics.Extensions.dll. This library is only built for Windows and Xbox360 and there is no support of this assembly on Windows Phone since it does not support custom shaders.
- Fixed an small bug in Pinch effect.
- A better implementation of ModelAnimationPlayer class in Hilva.Graphics.dll assembly. No breaking changes in the public members of the class.

Known Issues:
- On Windows and Xbox360 libriaries, an InvalidOperationException may occur when instanciating certain materials and post process effects. The thrown expection contains the following message:
“Cannot mix shader model 3.0 with earlier shader models. If either the vertex shader or pixel shader is compiled as 3.0, they must both be.”
