Blendspace animations of morph targets play at a slightly but noticably different rate between the 4.8 and 4.9 version of the UE4.
1. Download and add this project to your Unreal Projects folder: [Link Removed]
2. Open Launcher, locate and open "Blendspace_Debug" (v4.8) project.
3. Open map "CenterCube"
4. Play in Editor
NOTE: Striped square "pushes and pulls" striped post as designed *Slight overlap acceptable.
5. Close project and Clone project for 4.9
NOTE: Results are the same if you migrate assets to a blank 4.9 project
6. Open cloned project and open "CenerCube" map again
7. Play in Editor
RESULT: Square penetrates pole by about a quarter inch visually during the push part of the animation.
EXPECTED: The animation to play exactly the same way as in 4.8
