    hi all,

    I'm having a hard time finding in the manual (and so understanding) the difference between all the shaders.

    I'm baking my lighting in my 3D app. Which shader should I use for all these materials when they are brought into Unity? They are already lit, so don't need any other lighting info from Unity....?

    Yes, if all lighting is baked and you don't want any realtime moving lights, then use either Self-Illuminated or Lightmapped. The difference between choises insid e these shaders (VertexLit, Diffuse etc.) only makes a difference for any additional Unity lights (they add "on top" of the baked illumination).

    The difference between Self-Illuminated and Lightmapped:
    * Lightmapped supports colored lighting, with a separate UV set on the geometry and separate lightmap texture.
    * Self-Illuminated supports monochrome lighting, with the same UV set as the main texture; and the lighting has to be baked into alpha channel of the self-illumination texture.

    We are writing extensive built-in shaders documentation for the next release :)
