Hello! I’ve been having some issues with simulating muscles with the Chaos Flesh System in UE5.7. I’ve been using the Unreal documentation for 5.6, but I keep running into trouble with the Muscle Partitioning section.
In this step, the developer explains how to use weight maps to only keep a certain amount of muscles for the simulation test (these keeps the time smaller, uses less memory, etc.). I make sure I have all of the same settings, the same workflow in the data graph, and simulation preview, but anytime I try to record or play the simulation with only a few muscles, the tetrahedrons explode. After a while of having this problem, I tried just simulating with all of the muscles of the upper body (I added origin and insertion points to all of them), but Unreal couldn’t handle it once I got to skin binding. Has anyone else had a similar problem with this part of the tutorial?
Example of my viewport after only keeping a few muscles:
What the tutorial shows the viewport SHOULD look like:
