RPG Character Pack | RPG Barbarian Pack | Dragons Pack PBR (FIXED!)
These had an issue where the Copy This To That scripts weren't working. I've updated them and you can download them if you're registered in the "My Downloads" section. (If anyone finds another pack with the same issue, please let me know!) (Look for the downloads with the full title of the pack)
Copy This To That (All Versions)
If you copy all actions on a script that has a lot of "Procedural Materials" on it, it'll take a long time to complete. This is because Unity is doing everything twice, in order to save the changes. It's an annoying thing, but just be aware that it'll take a while to complete. Uncheck "Save Changes" in the Options area of the latest versions of the script to speed this up. But if you quit, any changes will not be kept.
Mass Exporter Won't Work (5.4.x)
[LATEST: 5.5.0b6 has a fix! I've not yet tested it, but I've been told it's fixed! So 5.4.x will *never* work with the Mass Exporter, but 5.5.x seems like it will :D ] https://unity3d.com/unity/beta/unity5.5.0b6 Currently "Mass Export" doesn't work in 5.4.x because of a Substance bug that adds " (Clone)" repeatedly to the end of the file name. Allegorthmic is aware and is working on a fix for a future 5.4.x update. Current 5.4 versions will never work with Mass Export, though. :(
