maya move uv shells into 0-1 from relative position.

malcolm

Does anyone know of a tool that will take uv shells and move them into the 0-1 uv range without changing their relative positions in the uv editor. I'm cleaning up some messy props and artists have their shells scattered randomly sometimes 100 tiles away from zero, I'd like to click a magic button and get these back in 0-1 without having to fix any uv's after the fact.

Let's say you want to move the menu to the right, just make the code below:

polyEditUV -u 1 -v 0 ;

Left

polyEditUV -u -1 -v 0 ;

and etc..

MoP

Well, bugo, that moves it by exactly one unit, which isn't exactly what he's after, and it'd mean changing the number for every different amount you need to move each piece.

He wants a one-click solution for pieces of UV anywhere outside the 0-1 range.
To do this you'd need to query the selection, find how far outside the 0-1 range they are, and offset them back by the opposite amount.

Sounds like a fairly straightforward script, I might take a quick look now...

MoP

malcolm: Try this... I just threw it together in 20 minutes now but it seems to work fairly well on the stuff I tried it out on. It may be a bit slower on objects with tens of thousands of UVs... it will work on any selection, but it'll be fastest if you manually select the parts you want to move into the 0-1 range first.

mopGatherUVs

Just copy this .mel file into your My Documents/maya/scripts/ folder, type rehash; into the MEL command line to refresh your script folder so that it picks it up (otherwise restart Maya).

Then make a selection and type mopGatherUVs; into the command line. You could create a shelf button for this command.

Let me know how it goes.

Obviously this is used at your discretion, I accept no responsibility for any loss of work as a result of using this script (although I can't imagine anything would break that much, and you probably saved recently anyway, right? ).

malcolm

Hey that is fucking awesome. You are quite the fancy pants scripter these days thanks a lot!

bugo

ahh, read wrong...

MoP

So it worked ok?

Whargoul

Hey Malcolm if you still have my toolset, it's called "normalize UVs" under the UV tab.

malcolm

Mop yeah it worked on a really fucked up object.

Cody I never had your toolset I just had random one off buttons you ripped out for me.

Well that was interesting, I downloaded that script and tried it out also. That may be handy somtime in the future. Does anyone know of a simlar script that would pack all the uvs in 0 to 1 space tight and equally spaced like in headus uv layout you can choose pack uvs.

Hi,

Arriving late to the party, but, does anyone still have the MopGatherUV script? The link's 404, and I've been looking for something like this for days now.

Thank you.

Hello everyone,

lod3, have you found it ? I'm looking for this script as well . Somebody please help !

Thank you !

athyri

hi there, i found the script via google, but it doesn't work for me.
http://www.ldaustinart.com/paul//scripts/mopGatherUVs.mel
i select the shells i want to move and type in mopGatherUVs;
for a second a small window pops up, but the uvs stay exactly where they are and nothing else happens...

athyri

with some small changes it works for me now. thanks alot MoP!

Hi

I have a problem with some models for a game, in the previous version I hat no problems with my models, but in the latest realese of the game I keep getting this error message on my models "Error: UVs out of range [-8,8]".

Question is, can I use this same procedure as "athyri" posted, or would this not work to correct these errors im getting ?

greets
Jegge

passerby

your not giveing us much info to go on, and also giveing us a error from a game engine you never told us about dosnt help much either since we dont know the requirements of that engine.

Sorry to dig up an old thread, but mop's tool no longer works in newer versions of Maya. Mop care to update your script?

passerby

just use nightshade uv editor or uv delux they add this feature + many more. what feature of it do you need? it also wouldn't take long to get any of this features working on python for newer mayas as well

Bartalon

If you don't want to deal with MEL script or special plugins just for moving shells around, you can just use the input line at the top of the window.



Just make sure it's set to Relative and X/Y will control up/down/left/right shell positioning. Moving it by 1 will shift everything 1 full tile.

bugo

nightshade and deluxe uv works like charm. Go get it! Passerby is right
