Title: Ivy is grown different on each frame.
Post by: Tobias Jansson on September 05, 2025, 07:51:39 pm

Hi!
I am having trouble with Forest Ivy in multiple scenes, however the problem only seems to arise when using the European varigated ivy. There is flickering between frames, it looks like the ivy is grown a bit different between the frames. I use the latest version of Forest Pack Pro and render using Vray. As you can see in the animation Everything seems fine except for the flickering of the european varigated ivy (look at the top of the archs). Link to youtube clip:

Thanks!

Hi Tobias,

We'll do some render tests here with the European varigated ivy.
Anyway, if you can send us a simplificated scene (https://forum.itoosoft.com/faq/how-to-send-a-file-to-itoo-software/) (we need only the ivy and camera), it may be very helpful to identify the problem.

Thanks,

Hi again!
Just sent you a scene that shows the problem. Perhaps the problem has to do with my ivy setup, I am trying to achieve a dried up and almost dead ivy with very few leaves..
Thanks

I am also facing same issue. Kindly suggest a solution. This mostly happens when the frames are rendered over network.

Please make sure all your render nodes are running the same ForestPack version — this caused the issue for another user. We’d appreciate any feedback you can share about this issue, either with us or with the user community, in case others run into the same problem.

Best regards,

Even if render nodes are updated with the same Forest version, it seems there is some problem which generates different results of ForestIvy. We are investigating it.

Meanwhile, a temporary workaround is to collapse ForestIvy to an Editable Mesh, and optionally save it as VRay proxy.
To convert to mesh, you must set Display->Viewport to 'Mesh'.

We apologize for the inconveniences.

Fixed in Forest Pack 9.3 (https://forum.itoosoft.com/announcements/forestpack-litepro-9-3/).
