I've made a model, I've tried to unwrap it using several programs but they all do the same thing.

For example, I'm trying to unwrap a face of the character ....when its "unwrapped" it looks like someone just took a screenshot of the front view of the wireframe, and its not flatted out at all.

Did I do something wrong when I made the model?

No, you have to actually do more work than just click unwrap. Technically if you want to unwrap the face you need to break it up: eyes, ears, mouth, face, hair. Then apply UVW maps to each, then you can unwrap them, but you still need to mess with the UV's to get them to work. Its really dumb but that's how it works.

What unwrapping programs did you use? I know how to do it in 3DS max and UVMapper.

Download or buy (or anything similar):

http://www.3d-coat.com/

Of course you don't need that app, it's just one I've used, just as long as you have on that works similar (Hexagon's UVMapper and Ultimate Unwrap 3D are two I can think of)

And follow my video tutorial, and listen to mah sexy voice.

Really? I thought I sounded a little camp.

Though don't be fooled, there are plenty of thick English people in the world, for a start, the Beckhams. Perhaps I should do my next video tutorial with chav lingo?

No way, a little low volume though But I've always thought that that kind of accent makes the one speaking it sound really smart and professional hah Not like my stupid voice (I really hate my voice... Like a lot of people).

On topic though, I would recommend the one Seppuku did, I don't have it, but from what I've seen it is very good at unwrapping.

Never thought I'd meet a person jealous of my accent, well it's TGC, there are a lot of weird people, so it was bound to happen.

But yeah, note taken on the volume.


But anyway, on the program I've recommended if you're going to download the demo and try it out - all of your tools you'll need are on your left panel, towards the bottom is a tool called 'quick uv mapper', that's the mode I was in: whilst using it you have the window you see in the video, that window not only show a preview UV, but certain tools.

'Clear seams' will remove any seam specific UV data
'Auto UV', the program will try to 'guess' a suitable UVmap
'Unwrap' will use the seams you've selected to set the UVMapp
'Apply UV Set' will set it to your model

So having your 'work mode' at 'seams'. clear your seams, then you can just select the seems just like I did in the video, hit 'unwrap' then 'apply UV set'. And you model is UV mapped. Then on your left side-bar, hit 'Draw with pen', to enter drawing mode to test out your UV on your model with a paint brush. You should be able to export to .obj, load it into your main program, paint a texture over it or something. Of course if you're editing in a paint/photo program, then certain parts of the UV Might be upside down - just like the back in my video.


Of course, if you can afford this program or your UV mapper is nothing like it, then I could do a demonstration in LithUnwrap, which is free, yet effective.

A partner? Not sure what you mean, chances are the answer is no. I just uploaded my Spore video straight from Spore - perhaps that has something to do with it?

Thanks for all the response

I understand now what I did wrong. I was assuming the programs were intuitive and that you could basically just point it to a head (for example) and it would unwrap the whole thing ....

I didnt realize you had to basically unwrap in sections.

Omega: the programs I was initially tried using were 3D Canvas Pro, Lithunwrap and UVMapper. But I'm going to stick with 3D Canvas because its fairly easy to understand.


Can anyone tell me what the difference between unwrapping and UV mapping. (I ask because 3D Canvas has those two functions as a separate thing, but they appear to do the exact same thing)

Unwrapping is guess you could say is the final step of UVmapping - the UVmappers I've used have an 'unwrap' button which is fairly self explanatory, it takes the data you've put in and unwraps the model for a UVMap.
