Hi,
Sorry to hear, you're facing these troubles. Unfortunately, just from the provided video, it's very hard to say what's causing this problem.
Please, be aware that the
Camera - Distance Falloff - Density feature, when rendering a "walk-through" animations, shouldn't be used to prevent any kind of troubles. As mentioned in our
online reference guide:
"Be careful if you use falloffs with camera motion, because items may appear or disappear suddenly (the distance to camera changes when moving)." If so, disabling it should fix it.
Would you mind to enable & send us the log by setting
General - Log Level to
Debug in any Forest object in your scene, before sending it to the renderer? The log file is located at:

Best regards,
