A compatibility fix to make it run in Max 2020. Info: https://www.itoosoft.com/forestpack Changelog (included the one from 6.1.7 I had forgotten about): Forest Pack 6.2.0 Added support for 3DS Max 2020. Fixed location of Forest Effects for Lite version. Forest Pack 6.1.7 - Fixed issues with animated V-Ray proxies. - Fixed crashing bug with Animation modes in V-Ray. Note: besides this fix, there is a similar (but different) problem in V-Ray which may cause an exception rendering animated GrowFX models. We could not confirm if it may happen also with other animated models, not GrowFX. ChaosGroup has fixed the problem in the latest nightly builds. If you are rendering animated models, we suggest to upgrade to the latest nigthly build of V-Ray. I did the (unfinished) render in Max 2019 instead of 2020 since I can't run Vray NEXT in my laptop. I'll try and do it in 2020 remotely, maybe tomorrow.
