IIRC you could specify different paths to world on deferreddemo's command line; check it's command line help. > I must say that parsing is not my strengh.

For some general information on how CS shaders are made up: http://www.crystalspace3d.org/docs/YoFrankieTutorials/crystal_space_development/shaders_intro/shaders_intro.html - that also includes some sample XML. And by seeing the “old” syntax you may already be able to guess how a syntax for the “unified” system would look. The actual XML parsing is already abstracted - i.e. you access XML nodes with statements such as ‘GetNode ("vp")’. > Also, do you support tess/geom shaders in Cg?
