I no have idea what is the best way to do it I made that animation using keyframes in Blender of course the camera focus the plane and then moves around, but how you can do this in Blend4Web ?
Using logic nodes will do the job ?
Or Is better to use JS I'm not sure. I guess I can animate the camera but that will stops the interaction, right ?
Thanks.
