Locking certain UV shells position while making a new layout

[glacialwinter]

Hi, I've come across this situation a few times, and I've never found a solution for this.

I'm making an customization to a vehicle, and while I've made a lot of modifications to the model, there are still a few areas that have been unchanged.

What I want to do is this: to make a new UV layout, while preserving the UV shells of the unchanged parts of the model, so I can import the model back to Substance, and keep those areas with the original texture, so I don't have to do it again.

But the problem is, when I run the Layout tool, Maya rearrange the whole thing.

I've tried using the Pin tool, but it doesn't work in that way.

The only possible way I can think of, is to do the UV Layout manually. But it is a complex layout, it would be a lot of trouble to rearrange all the UVs around the UVs I would like to preserve its position.

To illustrate what I'm trying to do, I'm posting a print of my Layout:

The highlighted objects are the ones I'd like to keep its position, while all the rest I'd have to fit around them.

If there is an automatic way of doing this, it would speed a lot my working process.

I appreciate any help.

Thanks.

Hi!

The layout tool (CTRL+L) only affects selected objects, so if you use UV-Shell Selection and only select the Shells you want to layout but not those you want to stay in place and the run the layout command it should only layout the selected shells and keep the others where they are.

I hope this helps!

Hi, thanks a lot for your feedback.

But that didn't help me.

What it does, in this case, is to make the layout on top of the parts I wanted to keep its place.

What I wanted to do is to rearrange the new layout to be around those shells.

But that is all right. I guess that is no possible solution for this.

What I did was to rearrange that manually. It actually took less time that I expected.

thanks

This would be a great feautre to have.

Meanwhile you could use rizom.

Hi, thanks for your feedback.

Yes, that'd be a cool feature to have in Maya.

I'll check out Rizom. thanks for sharing.
