Unwrap UVW turmoil (again)
show user profile  Garry
Hi all,

I'm still working on a project (5 weeks now) and I'm starting to NOT enjoy it. The reason is because of the unwrap UVW experience. Looking at the images below, this is what I'm getting very very very bored and frustrated with.

This is what happens when I click on 'edit' (this is one of the better ones too!)

When I unwrap something, it ends up in lots and lots of pieces. Sooooo I spend the next few hours stitching them together. Is it always like this? Why doesn't unwrap UVW 'try' to keep the shape of the original element?

This is what I get after hours of stiching and moving stuff

I've watched several tuts on the subject and I've tried using different mapping (flatten, unfold, pelt) methods but none of them seem to have the desired effect. I appreciate that there will be some tweaking needed, but sometimes there's dozens and dozens of things that need moving / scalinng / rotating just to get the desired effect.

Am I doing something wrong or missing something really obvious? Some help or advice would be REALLY appreciated because I don't want to quit this project out of frustration and I really want to see it to the end.

Many thanks for ANY input. :/

I don' know what tutorials you've been watching... but I think you're missing quite a vital step here.

"When I unwrap something, it ends up in lots and lots of pieces"

This, as far as I can assume... would be your fault then? You're the one doing the unwrapping, so the amount of shells/unwrapped pieces would be all up to you... surely? You say you've tried Flatten, Unfold, Pelt.... have you tried just selecting faces on the mesh and hitting Planar or Cylindrical (or whatever you need) and then adjusting how it aligns? ie... you could select the side of a car... go to the side view, hit "Planar" and then "Align To View".

Stay way from Max' automatic solutions. Oh, and untick the "Normalize" button too, if you want to retain 'aspect ratios' or whatever. (stops unwrapped pieces from squashing to fit into a square)

To make unwrapping easier i always put a good record on...something by the stone roses

Christ on a bike! I don't believe I've been that stupid! Is it really THAT simple? I thought I was supposed to choose some type of mapping inside the uvw editor??? I just needed to choose a mapping method and click "edit" ?? Waaaaaaaaaaaaaaaaaaaah

Seriously though, thanks alot Dave. I'll give that a try. Big thanks for the 'normalise' tip too. That's one of the biggest pains in the arse for me, when it splits the mesh into 20 million pieces and scales/rotates them all wrong :(

If I were that way inclined, I'd kiss ya. But I'm not - so have a handshake instead :D

*edit* hmmm I've just tried the following steps and got the same result as the first image above...

stuck the unwrap uvw modifier on
chose face - select by element
selected the required polys
clicked on 'Box' (and it was aligned perfectly)
unticked 'normalize map'
clicked 'edit' then got the above result.

Maybe it's just max then? and I'm not being a complete spaz?

Mak, showing your age there..."record" :D Aaaaah I remember them ;)

I think The point Dave is making is you can unwrap certain parts of your model one at a time, to do this select your faces( uncheck select by element) apply the appropiate selection the editor choose "filter selected faces" and maybe try 'unfold mapping'. move the UVs to one side and then choose other faces, and repeat.

It maybe that you want a perfectly unwrapped model with just one discretly hidden seem in which case youll be dissapointed. Mind you using pelt on come parts of your model will allow you to choose the seem placement.

Thanks mak, that does seem a bit long-winded. But, if it works then I'm happy. I'll give it a try tomorrow.

"clicked on 'Box' (and it was aligned perfectly)"

Oh, yeah... stay away from Box too! In all honestly... the only things I ever use are Planar and Cylindrical Mapping. That's it. Used to use Pelt on organic shapes... but have since turned to third party applications for that task.

Planar is what I mostly use though... like 90% of the time (on non-organic shapes). Probably not going to be able to see this very well... but this was the last "big" unwrap that I did... using Planar A LOT. And then stitching pieces together (ie, instead of stiching faces, you stitch different planar unwrapped pieces).

I almost always use 'flatten' on the entire mesh, then stitch everything together, like you did in your first example. Its just that ure slow...damn slow...that simple mesh should take minutes to stich together, not hours...once u get faster its not that tedious.
Dont move each piece and weld it, that can be done in one step with the 'stitch' feature

lol that example above only took a few minutes. There was a horrible unwrap which had loads and loads of scaled/rotated/distorted bits. - That's the one that took over 2 hours :)
