Hi there.
I have a scene with many forest objects (56), and at least 30 Forest Sets.
Things are painfully slow when the forests are active, particularly when creating new items, moving things around in the layer stack, duplicating items... every time I make a new object, it takes a long time before I can do anything. When drawing a new spline for example, I make the first click and then have to wait about 20 seconds before I can draw the spline. It's not related to camera visibility options, or number of items within objects, or viewport display.

I have no surfaces set to auto. The issues are resolved if I disable all of the FP objects, which is what I am finding I need to do to edit the file at all - even with everything set to frozen, the issue isn't resolved.
This is not unique to one file - all my projects have many FP objects and I have these slowdowns with all of them, frustrating and time consuming. I have just never got around to submitting it as a bug.

Another issue is that sometimes (Often when I first open the file) if I expand a layer with FP objects on it, it takes a long time to expand.

I downloaded the latest update today (v9.3.2) hoping from the changelog that the issue might be resolved (I read about the FP Sets causing issues with layers) but this hasn't resolved my issue.
I did try and delete all the fp sets out of my file, and this did fix it but I'm not sure if that was just because the FP's were now all broken and missing their geometry.

Any ideas?

Hi,

I’m sorry to hear you’re experiencing these issues. Since Forest Pack 9.3.1, a problem where ForestSet triggered a Forest rebuild when modifying layers — even if ForestSet wasn’t using layers — has been fixed. Based on your description alone, it’s difficult to determine what might be causing the issue. Therefore, if possible, please send us your scene so we can review it here. Thanks in advance for any additional details you can share that might help us identify the source of the problem.

Best regards,
