So as I have been using BabylonJS for over 2 years now ( amazing engine! Great work!! ) I was having a couple of ideas running through my head which I think are worth discussing.
Second, I think Babylon is the greatest 3D html5 gaming engine around, I truly believe it and I think it deserves much more exposure and usage. A barrier many developers face is the lack of assets. Not everyone can make 2D or 3D assets, the assets which are online most likely are not optimized for the web or would not work well with Babylon. How about an assets store? Babylon is already an html5 3D gaming ecosystem, maybe an assets store would really help people join. It could be anything, from scenes to animated 3D models or GUI and they can be tested right away through the sandbox.
These are just a couple of ideas running through my head and I thought to share them with you. Let me know guys what you think about them.
