FYI to our modding community.
With 1.30, like with all prior updates we expect animation mods to break. But unlike with all prior updates the way the breakage will occur is much larger. Previously animation graph files were saved in a non-generic format specifically tied to the animation system. Now they are saved in the same config format used as our UI layout files.
Player graph modifications/extensions:
Previously in 1.29 and prior, a modder would be able to use simple text editor tools to compare their animation graph files and our updated animation graph files to see what they would need to take.
Now with 1.30, this text file has completely changed format and so they would require to re-do their animation graph file changes from scratch.
There are new limits in place to various systems that weren't there before, such as the number of groups.
Custom animals/infected:
It should be a painless upgrade process, though the tool behind it in Workbench was not tested. The process behind it that modders should do is open the old animation graph inside Workbench and then re-save the entire workspace.
