    Hi. I found that Unity 2019.3.13f1 does not set zero for missing vertex attribute value.

    In example, if the mesh in FBX has partial UV3 (some vertex has UV3 and others not), Unity will import it as 0 for missing value. Unity 2019.3.0 did like that. But Unity 2019.3.13 doesn't. It set to something random value. I confirmed that Unity 2019.3.12 and 2019.3.13 set different value but still not zero.

    Minimal reproducible project are sent as Case 1246876.
