as described in Blender Shader in OpenGL/GLSLBlender Shader in OpenGL/GLSL, it is possible to export the (unoptimized) GLSL code generated by Blender for a given material.
Since the viewport can use such GLSL for real-time shading, my understanding is that Blender could be used to fully design and preview assets for real-time applications, without restricting materials to existing shaders/parameters (since nodes can be used to design a large variety of GLSL-exportable materials).
But exporting GLSL shaders manually for each material, then exporting geometries, and finally associating them in the final render engine does not seem like an efficient workflow.
So I was wondering if there exists any Blender model exporter (whatever file format it exports to) that does export generated GLSL code alongside geometries?
Regards.
