This is very cool Johan. I have some questions if you have time to answer:
Do you believe your headless platform POC would allow the use of the snapshot method for exporting visuals of a scene to a png? If so do you have any early indications of performance therein? (number of snapshots per second etc) Will the headless platform support the 3D Nodes/Camera etc? Thank you for your work and your time answering in advance.
