Alternative to Mdlvis? (need program for attaching vertices to bones)

[Tigrick]

Mdlvis messes up normals.
I tested it. Each time you open a model in Mdlvis, it changes normals, and this can make a model's lighting weird.

I want to find another program that allows attaching vertices to bones. Suggestions welcome.

I must be blind, I can't seem to find a way to attach selected vertices to a bone in Retera.

I can select vertices and bones, but it ends there...

Select the vertices>right click>Re-assign Matrix>select the bone on which you want the vertices to be attached to.
