bug causing trees to dissapear

[sayito]

Hi, we installed forest pack lite a couple of days ago to test it before we buy the full version. We are having an issue with the trees disappearing in our scene whenever we update any of our xref'd files or add another xref scene. Can this be fixed? does this bug exist in the full version?

Forest Pack Lite 4.4.1
3ds Max Design 2015
Vray 3.20.02

and yes... all our software licenses are legitimate

Hi, actually there are not known issues with such behaviour.

What is the state of the Forest objects when that happens ? Can they be selected and edited, dissapear completely or what ?
Can you see the trees on the viewport ?
Are you using library models or your own objects ?

Forest stores their trees in a hidden layer (forest_templates), as meshes or XRefs (depending of the option selected in the Library browser). Perhaps some Max operation is removing them from the scene.

They can be selected and edited but the tree preview in the view port never comes back and the trees don't show up when you render either. We are using the standard trees in the forest lite library.

If the forest object is in an xref file as opposed to the main file, updating the link makes the trees come back. I can't get them to come back if the forest object is in the main file though.

Please send us a test scene to support@itoosoft.com and we'll check it. For large files, please use a web sharing service as WeTransfer.

Thanks.

Hi, this is a typical problem when editing scenes which a been created with a non-legitimate Forest license.
In this case, just delete those objects and recreate them using your license.

If you want to verify some specific scene, please send it to support@itoosoft.com. Thanks.
