When MS is Calculating Vertex Colors at the end of the Build Model job, it just 'seems' to hang, as there's no indication of progress.
And with the projects i've recently been processing, it's taken much longer to calculate them, it seems, and with very little CPU usage. A bug possibly?
So could Calculating Vertex Colors get it's own Progress Bar, i.e. it resets to zero like it does for the other sub-tasks. And/or updating the console with % updates...
E.g.:
10%
20%
30%
etc...
If we're processing 'big' jobs, on crappy hardware, where these things take many hours, days, it's quite unnerving wandering if it's hung!
