Ok, thanks Juri.
I'll investigate this further prior to choose a platform, Blend4Web sounds cleaner than Unity, but I'll have to pick the most practical for this, deadline is coming !

Hi, I'm starting developing an app, it's a sort of multiplatform viewer (browser), synchronized in real time with a scene being edited or played (animation frames) at live in Blender , so basically I want to know if Blend4Web has native API support for this (3D data live streaming ) or if there is an API feature to start with.

Thanks!
