Hi There,
I've found a bug in the latest release of Forest Pack Pro version 8.1.0 that wasn't there in 8.0.9. I can confirm that rolling back to 8.0.9 fixes the following behaviour:
In my scene I have a number of Forest Packs where the objects that it is using to scatter are V-Ray Proxies. Specifically they are V-Ray Proxies that have their viewport visibility set to one of the quick preview settings ('preview from file (edges)'). In general I always have my proxies set like this as it can dramatically speed up viewport performance. Recently I upgraded my Forest Pack Pro installation from 8.0.9 to 8.1.0. Upon re-opening my Max file (latest version of Max 2023.3 Update) I was greeted with a viewport full of masses of crazy geometry. Eventually I tracked it down to the Forest Pack objects. I set my Forest Packs to be visible in the viewport as pyramid obects, again for viewport interactivity, but now all of my Forest Packs were displaying as if the link back to the V-Ray Proxy object was broken i.e. they were now displaying as large boxes.
Obviously I checked to see that the proxies were pathed correctly, and they were. I tried manually clicking on the Build button Forest Pack, but no difference. I then selected the V-Ray Proxy object itself and changed it's Display Preview type from 'preview from file (edges)' to 'show whole mesh', and bingo, the Forest Pack repaired itself and displayed correctly as little pyramids. This had to be done maunually to all the proxies used by all the Forest Packs.
Obviously this process can be sped up by selecting all the proxies at once and typing '$.display = 4' in the command line input box, but it's very annoying to have to do this. Even worse upon saving and closing Max, then re-opening the file again, the Forest Packs have all gone back to displaying as a crazy jumble of massive boxes.
Uninstalling FP 8.1.0 and rolling back to 8.0.9 completely fixes this issue. Could you look into what is causing this please? Currently I am unable to use the latest version
Best regards
