It has no effect, and I'm hoping it's a simple solution like when I was having a similar problem with the morph brush. Also, I am having trouble getting decent results in the fitting room in general. Have read that part of the manual and watched videos. Advice? Was not able to post my last (longer) message and don't know why; that's why this one is so short.

The vertices don't change color like they do in the video. Like the tool is having no effect. Anybody else had this problem? How is it fixed? I am using Poser Pro 2014. Thanks.

Make sure you don't have "Group" checked.

Group isn't checked. What should I try next?

It just spontaneously decided to start working, like many things. I sometimes think my computer is possessed by djinn. I am still not very good at the fitting room, though. What happens is that I get the item fitted pretty well before going into the fitting room, and it comes out fitting worse than when it went in. And I sometimes have the problem of pants melting together in the middle. How do I tell it to be more gentle with my clothes? I've tried disabling certain fitting methods or reducing the strength of them, but it doesn't seem to help.
