- Refactored paralax calculation code in Parallax.glsllib
- Added a boolean param to lighting material PackedNormalParallax to specify if the parallax map is stored in the alpha channel of the normal map (it was already implemented in the shader). added a dds file and a material using this
- The parallax height can now be set by users by setting the ParallaxHeight attribute. default is 0.05
- Deleted old normal map for water
- Inverted green channel of the brickwall normal texture to look good with recent change in normal calculation in lighting material
- Created a test case for parallax mapping where you can swich from classic to steep parallax using spacebar, and where you can tweak the parallax heigh by using I and K keys.
