Shape Matching constraint: Obi Softbody vs Blueprint editor? - kodra - 04-04-2024
The ObiSoftbody component has some parameters for Shape Matching constraint:

However, in the Blueprint editor one can set those constraint per particle:
[attachment=2017]
My question is: how these two work together? For example, if I set "Max Deformation" to 0.8 on ObiSoftbody, but I set a particle's Max Deformation to 0.4 in the blueprint editor, then what does this result in?

Hi Kodra,
The ObiSoftbody's parameters are multipliers: they will take whatever per-particle values you set in the blueprint and multiply them with a global value. So in this case, 0.8 *0.4 = 0.32.
Should you need to change this, you can find the implementation in ObiShapeMatchingConstraints.cs, line 182-ish:
Code:
materialParameters[(m_ActiveConstraintCount + i) * 5] = batch.materialParameters[i * 5] * user.deformationResistance;user.deformationResistance would be the value set by the ObiSoftbody component, while batch.materialParameters[i * 5] is the value set for each individual constraint in the blueprint editor.
kind regards,

I see. Thank you very much for the answer!
