Still kind of disappointed that the “scaled bone” bugs aren’t fixed (root motion extraction must be upscaled, still can’t build correct physics assets), but I suppose that’s what my stupid self gets for using Blender without reading the UE docs first.
After fixing three bugs the update introduced (having to break certain HUD calls out into the event graph because of unpure functions, having to retune some anim end times in a couple montages to realign notifies and segments, having to go find all of my Vector Equal nodes and put a nonzero value in the error tolerance because the pre-4.6 default was nonzero and it broke input-axis-related stuff), I’m SUPER happy with it. BPs (mine are COLOSSAL) load and move around faster, and I no longer have to spend 5 minutes every time I open a session changing particle collision channels and resetting DataTableRow assets just to get the project playable again.
