Shaders
Default Oxygine shading is based on "Uber Shaders" system.
Shader source is located here: oxygine/system_data/original/system/shader.glsl
It is already embedded into Oxygine source code and can't be modified directly. If you want to change it then copy shader to Application data folder (working directory).
Example
examples/Demo/src/TestUserShader.h has example how oxygine rendering system could be extended.
