Items dissappear in video rendering

[Carlos Gamundi]

Hi. I have forest Pro updated to the last version.
Work in a video for a big golf scene i noted some items in the forest dissappear when I render the frames. I upload a short part of the video and you can see the change in the shadows of the trees.
In the scene doesn't exist any animated terrain or element.
I can't upload the scene right now because is too big file and my internet isn't good. 
Thanks.

Hi,

I'm sorry to hear you're experiencing these difficulties. First, I’d like to point out that the Camera – Distance Falloff feature should be avoided when rendering walk-through animations. As noted in our online reference guide, this feature can cause objects to suddenly appear or disappear due to changes in camera distance during motion.

I would recommend switching to Custom Edit mode, as the issue may be related to surface evaluation. Please use the Surface > Place Items button, and try disabling the Surface > Non-Image Modes > Link to Surface checkbox to see if that resolves the problem.

Thank you in advance for any additional feedback you can share - either with us or the user community - in case others encounter a similar issue.

Best regards,
