This issue is still very much affecting developers today, preventing me from being able to implement directional movement animations through blending walk cycles.
As many games are working around this issues by creating their own replicating systems, or even resorting to semi-custom characters, it would be fantastic if this is looked into. Especially since @Davidii worked on a solution in the past and the Speed property of animations does replicate correctly, which is nearly identical in the ways of interaction and replication.
Upon further investigation I found out that there is one working way to replicate the weight of animations to other clients:
- Play animations with a weight of 1 (not 0)
- Ensure AdjustWeight never sets to 0 (0.01 at minimum)
The issue seems to be related to other clients stopping animations when Weight is set to 0. By using this workaround you can achieve your desirable effect until Roblox fixes this issue.
Here is another bug report about the 0-weight issue specifically:
