I wish to display models (created by Maya) inside a 3D game, where the game engine renders the models as closely to Maya as feasible. Currently we use the FBX SDK to access the models vertex positions and normals and also store basic material properties (diffuse/specular maps) which we can apply to the model inside the game engine.
An artist has recently provided an Maya file which has a model which has been set up to look 'cartoony' and as such uses a toon style shader. How would I go about getting this into our game engine? Is the shader (HLSL? GLSL?) stored inside the FBX? If so how do I go about accessing it, and finding out what attributes/uniforms need setting up to be passed to the shader, etc.
If it is not possible to access shaders in this manner, could you suggest how we should go about bringing context from Maya into game via FBX files? It would be quite limiting if we can only support the basic material parameters. I am aware it is possible to write custom plugins for Maya, so we could create a custom material node, and write a customer exporter, but the amount of work required for this would make the task problematic (and is one of the reasons we hoped we could use somethign off the shelf like .fbx).
