Actually, the Rifle pack does have root motion, absolutely. The root bone travels around and turns with the character for sure, just like the Mobility. Many folks that own the pack can attest to this, so I’m really not sure what you are looking at or doing to think it is missing…?
Actually, I might make a short video of our animations in the creation software (Motionbuilder) to show all folks that aren’t animators what they look like under the hood and how they are constructed. A lot of sharp users and programmers know how it’s all supposed to work in UE4 in detail and when it’s right or wrong, but aren’t totally familiar with what the hierarchical animations really look like making it work or not.
Anyway thanks for all the other comments/info, thought I’d just address the root motion really quick. I think was planning on looking at the pack some more and jump in on the conversation, so hopefully he’ll post something soon and go over things as well better than I can.
