@cloudou A workflow that may work for you is:
Animate different empties to represent your camera views in Blender. Use Copy Transform
constraints to attach your camera to the empties. Then you can keyframe the visibility (or influence sliders) of these constraints, and in doing so "hand-off" the camera between the empties.
Example setup: empty_handoff.blend
When you're done animating the empties and constraints (remember to Save As
), you can bake the camera's movement.Object > Animation > Bake Action
Remember to enable the Visual Keying
option so that the effect of your constraints will be taken into account.
Example result: empty_handoff_baked.blend
The only drawback of a sudden camera hand-off is that if you are using motion blur it will blur between the huge leap the camera takes and look wrong. Currently B4W does not have motion blur, so don't worry about it. There is indication that motion blur is planned for the future
, but by then support for multiple cameras may also be added. Anyway, this technique is something you can use for now.
