If it's possible I could use a shorter virtual track for people movement.

Situation ... people climbing stairs .... ???

Ran across a layout using a combo of portals and virtual tracks to "climb" stairs. A very clever idea !

The problem I ran across is the smallest virtual track I can have  is longer than most steps used in objects. So people must climb two or more steps at a time.

Other situations I have had, related with moving people, a shorter track would have been desirable.

A rare application I realize ... if it's possible, and not a pain !

Thank You @Phrontistes ....

I thought I tried that and could only reduce it to 5.48 in length. Then I though  that was it's minimum.

After reading your post, I went back and edited the "track" and it worked.

Now I'm questioning my mental state !!!!!

You're welcome.
