The latest version of Zoo Tools Pro fully supports Maya 2025 with Qt6 for all UIs. This release is the first to be compatible with Maya 2025, and all tools are up and running in this version.  Please note that Hive rigs created in previous Maya and Zoo Tools versions may need to be updated to be compatible with 2025. See below.  Enhancement: Full Maya 2025 Support This version is fully compatible with Maya 2017-2025; all tools will be supported in 2025. Hive Autorigger is 2020+, and Chat GPT is 2022+.  Bug Fix: smooth Skin Weights (Brave Rabbit) We fixed a bug in the Zoo UI for the third-party Smooth Skin Weights tool. Strength was previously being set incorrectly while flooding.  Import Note: Hive Autorigger Rigs created in previous versions of Zoo Tools may need to be upgraded before coming to Maya 2025. This is due to a minor Hive bug that the earlier versions of Maya accepted, but unfortunately, 2025 does not.
