Thanks for your response, but it is simply not working whatever I do. What I did…
- First I set all the Anim Slot and AnimMontages to DefaultGroup.Default Slot
- I deleted all my own Slots.
After this… it keeps creating DefaultGroup.DefaultSlots. I got 3 in total at this time. - I created a TestGroup.TestSlot and set all montages to this Slot.
- I deleted all the Slots in the Animation Graph and was now able to delete all the DefaultGroup.Default Slots. Restarted UE4.
- I created a new Animation Montage, and a new DefaultGroup.Default Slot was also created as expected.
- I created a new FullBodyGroup.FullBodySlot. and Also created a new SlotNode in the Animation Graph and set it to this AnimSlot.
- Restarted UE4 and hoped for the best… but unfortunately the FullBody Slot is again placed in the DefaultGroup. ( a new slot DefaultGroup.FullBody Slot is was created)
I cant get to my needed Slot Setup… I also created a new UE4.9 project and migrated the content, but got the same problem.
I have to stick to 4.8 till this is fixed…
