[osg-users] Export shader programs to external files

[Sebastian Messerschmidt]

Hi Johan,

I had the same problem when exporting "shader decorated" scene graphs. 
My solution was to run a visitor prior to saving which will save the 
shader and replacing the programs (and now the shader defines too) with 
a UserData entry.
When loading the scene graph I replace the UserData with the shaders 
again. Maybe there is a more elegant solution, but this worked pretty 
well for me (as there is no support for shader define serialization yet)

Cheers
Sebastian

> Yes but the exported database will still have it’s shaders accessed internally, as far as I know only .osg can load external shaders but the .osg unfortunately don’t support Texture2DArray. The purpose of have the shaders separated from the database is to be able to tweek the shader code without regenerating the database.
