Hi, I'm new to Headus. How do I select and drag multiple UV points at once?

Hi,

You can't select points per se, the keys that you need are these:

Ctrl-MMB : move single point
Ctrl-Shift-MMB : move connected points
Shift-MMB : move points in circle
-/= : change brush size

These will allow you to move points within a mesh.

Hope that helps.

Kind regards,
Geoff

Thanks for the help. I got a new problem now. Whenever I am cutting my edges, an entire edge loop is cut, but two verts are still stuck together even though all edges were detached. And when I take it into the UV mode to flatten it, they stay stuck together at this one point and it won't come apart.

Hi,

Looking at that image, I don't think everything is fully cut - there appears to be no green edge to the lower right face. This might be a redraw problem, or it could be that the edge is folding in on itself. However, the left shell part is green right down and should separate.

You haven't said which view this is in, but I'm guessing it's in the Edit view, so try holding the space bar down, then click MMB on the left hand shell part and drag it away to the left - if it is separated then it will move apart on its own.

If you are then done with cutting that shell piece just drop if (point the mouse at the shell piece and press D) into the UV space; then press '1' to check that it's there and is fully detached. You'll need to flatten it - point at it and press 'F' a few times - but that should have sorted that one, press '2' to go back to the Edit view and continue with the other shell piece(s).

Hope that helps.

Kind regards,
Geoff

"How do I select and drag multiple UV points at once?"

There's the hotkeys that Geoff listed already, but you can also press and hold the G key to mark polys, then if you use the Space-MMB combination over the marked area, you can move, scale or rotate those UVs. The brush size in this situation determines the width of the effect at the marked/unmarked boundary.

"but two verts are still stuck together"

I agree with Geoff ... from what we can see in the screen shot, the bottom right edge looks unusual. I think I can see just a touch of green edge at the start ... maybe its a super thin polygon, and the reason why the verts aren't detaching is because there's more super think polys there. Zooming in might reveal whats going on, or you could use the G key marking again (mark polys then use Enter to detach them).

Thanks for the help. I tried everything but still couldn't get that cut. So I gave up and just did that part in Maya. Still don't know what the problem was since in Maya, double clicking on an edge grabs the entire edge loop, and doing that worked fine in Maya. But I thought shift-C selected an edge loop in headus, but it just wasn't working. And this same thing happened multiple times when trying to unwrap a camera I was working on.

All I can say is that normally it works. I'd have to have your file here to work out exactly why the edge loop cutting is failing for you sometimes.

I also have a problem where every now and then the program will freeze. In the bottom corner, it says LMB: Flatten-box enter: abort or something similar. And I try both, but it is just stuck. Can't move around, can't save, can't do anything. So I just leave it for about 30-60 seconds, and then it unfreezes. Any idea what caused that?

If you tap the F key and the mouse pointer isn't over a shell, then it'll bring up that menu. The idea there is that you can select multiple just dropped shells and they'll be squashed down ready for further flattening.

Anyway, you should be able to use the Enter key to get out of that menu, or just LMB clicking somewhere will do that same.

Ya sometimes hitting enter will abort and sometimes it won't. More often than not it will freeze whenever I hit enter. So I end up just taking a short minute break while keeping the headus window open. Then when I see that text in the bottom corner go away, I get back to it.

Which version are you using? (i.e. version number, Pro vs Hobbyist, and Win, Mac or Linux)?

If you click the "About UVLayout" button at the top of the GUI, it'll tell you the version and build date too actually. The most recent 2.06 release (i.e. 2.06.03) was back in April 2010, so you're missing out on a couple of years worth of bug fixes there. I'd encourage who-ever is in charge of that lab there to update the version they have.

Oh wow that is very out of date! I'm going to try the trial version on my own computer and see if that fixes the problem. Unfortunately at school they often pay more attention to the PCs than the Macs. Thanks for all your help! I'll make sure to post back on the forums if I encounter any other problems.
