Sample scene FBVS error: Unsupported conversion of vertex data

[josemendez]

Hi,

I just load the sample FullBodyVolumetricSoftBody, and hit the play button, but it shows: 

Unsupported conversion of vertex data (format 0 to 4, dimensions 4 to 4)
UnityEngine.Mesh:SetBoneWeights (Unity.Collections.NativeArray`1<byte>,Unity.Collections.NativeArray`1<UnityEngine.BoneWeight1>)


OS:win10
Unity ver:2020.3 lts
Burst:1.5.6
Collections: 1.0.0-pre.6
Jobs: 0.11.0-preview.6

Please help!
Thanks!

Hi there,

This error is thrown by Unity because your project does not support more than 4 skinning weights per vertex. Either enable them in your project settings, or set the "Max bones per vertex" property in the ObiSoftbodySKinner and click "Bind skin". Note this will reduce skinning quality.

See the manual:
http://obi.virtualmethodstudio.com/manua...inner.html

Max Bones per Vertex: Maximum amount of bones that can influence a single vertex.

Note that by default, Unity supports only up to 4 bones per vertex. You need to configure your settings to allow for more than 4 bones, otherwise Unity will throw an error at runtime when this property is set higher than 4.
