Hi,
I’m new to Unreal and I’m having trouble using Chaos Flesh in a realtime simulation. I’m working with a 3D model composed of many separate StaticMesh, each one with at least 4000 vertices (I cannot modify this model too much, other than doing some remeshes) and I’ve to use Unreal 5.4.
I’ve successfully implemented one FleshAsset with a single mesh using as reference tutorial that I found online and below I’ll put an image of the dataflow graph I use: the number of Num Cells parameter in component GenerateTetrahedralCollection is set to 70 with IsoStuffing. However, when I try to create another FleshAsset with another StaticMesh with more vertices, I don’t understand how to use correctly Num Cells: if too low (I’ve tried up to 200), it is never enough to reconstruct the mesh, that will have holes and in simulation it won’t interact the correct way with the other objects; if too high (we talk about 1000 or more), my computer tries to compute the tetrahedal collection, but it will stop and eventually crash.
Now, how does Num Cells parameter work? How is it related to the number of vertices of a single mesh? If someone can help me understand how the component GenerateTetrahedralCollection works in general, I would really appreciate that.
Thanks,
