It's a vacation time, so there are only few changes in terms of code. However we have news in art content and documentation. We would like to introduce our technical writer, Valentina "fattie" Vaneeva. She is a highly competent person, prior to joining us Valia worked in ALT Linux development team as a translator and in Mozilla Organization as a chief of Russian localization team. So, for more than a month our reference manual has been being in safe hands, there is almost completed new "Technologies" section ("Lighting", "Shading", "Bump Mapping", "Shadows", "HDR Rendering", "Postprocessing", "Transparency", "Reflections", "Special Effects" and more to come) with a lot of pictures. This chapter of the reference manual is devoted to modern real-time technologies of virtual worlds in general, it would be useful for artists as well as programmers.
