I think this example is what you're trying to do.

Overall, you need to run your 3D model in a Graphics Engine.
Like Unreal or Unity.
The video generated in the Graphics Engine is shared via Spout to Resolume.
Then, we must find a solution to control all this.
I don't know if the graphics engines include MIDI instructions.
But in the example, it seems to be OSC Controls, integrated in the corresponding FFGL Plugin.
Then, it is always possible to set MIDI controls on the FFGL Plugin parameters.
I have my own question on the subject:
Is it possible to mix textures in resolume.
To send them to the graphics engine. Resolume > Spout > Graphics engine ]
That it be applied to the 3D Model.
And to retrieve the textured 3D model in Resolume. Graphics engine > Spout Resolume ]
If anyone knows the answer :B
