validation of mesh for automatic unfolding (warning : only meshes of 1000 triangles max in this version)

In the free version it can only work with 1000 tri's max. Wings3d's autoUV unfolder is good enough for me.

With an RRP price of 900 euros and 200,000 poly limit it better be damn good,

Yes this really looks good, it's about time for something like this. The price is a bit high though. I mean 890 Euros for what is basically a one-trick pony? You can get a whole 3d program for less.

I agree, it is too expensive. Too bad the free version is so limited.

Seems nice but I must agree, it's way too pricey for my taste.

That price is a joke! =]

You can do the same thing in blender for free, with no triangle limit.
Houdini's UV Pelt and UV paint tools can also achieve the same results - again, free if you are using Apprentice. XSI also has some form of seam definition and auto unwrap combination - though it's not as refined and clean results require further tweaking in the UV editor... still you get some kickass UV tools in foundation for half the price, with a full 3d app thrown in on top - or free if you use the HL2 mod tool version.

For me the sweet spot on such an app is about $120 USD.

Yeah, I'm with Dex - I wouldn't spend much more for a UV Editing App.

The movies look damn nice, though...

this looks very similar to uvmapper in Wings 3d........

but wings sucks for this purpose since it only handles solid meshes right? I tried the demo of unfold3d and it was great, ofcourse only tried on lowpoly stuff tho, Id love if they lowered the price as well, Im with jdex here, 100-200$ seems more reasonable. However, if this tool really does most of the work, and say a 3d artist cost 1000$ a day, you can save the money it costs to buy this app rather quickly.

this looks very similar to uvmapper in Wings 3d........

I did a lot of unwrapping with wings so far, and to be honest, 'solid meshes' is only sometimes inconvenient, but by no means fatal - wings tries to make any imported mesh solid (and exports it back 'open' if you wish so).

You can do the same thing in blender for free, with no triangle limit.

Indeed. Just import your model as .obj, set your seams, unwrap, pin some verts, recalculate the uv layout and export out of Blender as .obj.

Just look at the "Making of Lord of Darkness" thread in the header on the main page here. He used Blender for the UV layout and it didn't cost him a cent.

Yeah I just tried this, seems to work fine even with holes in the mesh. However, I tried to unwrap the same head in both unfold3d and wings, unfold3d did a much better job, less stretching etc, and yes, the UV layout itself was similar in both programs. Makes sense tho as unfold3d does cost a fair bit, it should be better than the free alternatives.

Thanks.

********************************************

Hi everyone,

First of all, please excuse me for my broken english.

I am working on the unfold3d development, and I really want to say several
things about this software.

1/ About "Texel density preservation" (stretching)

It is true that unfolding with unique UV produces streching most of the time
(it is even proven mathematicaly, we cannot deal with that if you want an
unique UV). But it is also proven that it exists a solution (UV coordinates) which
minimize stretching : Unfold3d can give it to you...

With Unfold3d, the presence of stretching depends on two factors : a) the
curvature of the surface b) the cut out of the mesh.

If your mesh posesses hight curvature zones, your UVs will posess more streching.
But you can minimize again the stretching by choosing an appropriate cutting line.

2/ About the problem with XSI "XSI UVs, completely messed up"

Try this with XSI 4.2 :
a) take a mesh
b) visualise the position of a vertex, for example, the vertex number 50.
c) export the mesh in OBj file format, and then Re-import it.
d) visualize the position of the vertex number 50.
RESULT : the position of the vertex has changed ! What happened ? XSI has done a
renumerotation (re-classification ?, I dont know the right english word). This
is a "bug" in the OBJ import/export of XSI. And therefore, it creates a
problem in the geometry <-> UVs links. Finally, the problem comes from XSI and
not from Unfold, this explain why the problem disappears under 3ds max.

In future versions of Unfold3d, other file formats will be available to improve
compatibility.

3/ About the LSCM unwrapping method.

The Least Square Conformal Mapping method give solutions (UVs) of a "linear"
problem (problem solved by Unfold3D is non linear problem). The UVs given by this
method are not always usable, mainly because it creates triangle flips and
gives a lot of stretching.

Of course these remarks come from an "non objective man"... So try by yourself :
compare !!!

4/ About the price...

The studio edition is designed for studios, this explains the price.
In some days, a kind of "personal edition" of Unfold3d (that version Studio
Action Synthese used to make Magic Roundabout production) will be available too,
and the price will be lower (near of the EDUCATION edition price).

5/ English Version of the Free edition

The english version comes in two or three weeks.


5/ Some words

Honestly, I think that Unfold3D is really a good app that can save you a lot of
time. If you have any questions or comments, please write them in our forum :

Sorry for my poor english, and...

THANK YOU VERY MUCH FOR YOUR COMMENTS !

First, sorry for my very bad english :blush:

I saw the full version in a 3D festival (e-magiciens) and I think it's a very good app.
You can have very quickly a good uv map with no stretching !!!

Sure it's too expensive for user like me but I can imagine it will be integrated in 3dsmax 11 or 12 :D ( I can dream.... ;)

I just noticed that there is a freelance edition for 195 Euros up there now...

Hi everybody,

I am very glad as a member of Polygonal Design company to tell you that we just made available lastest free version of UNFOLD3D for download on our web site. This time both french and english versions are available.

Besides, we just started a new forum dedicated to english speaking people. URL :
http://fraternaware.free.fr

Please feel free to subscribe and to contribute the way you wish.

By the way, some people asked for plug-in versions. Who else is interested in, and about which 3D software ? Please let us know so that we can determine priorities. Let me say, too, that UNFOLD3D is a scriptable software, and so this feature may ease its use with common softwares.

Thank you very much for your attention.

Regards,

Denis F.

A 3dsmax plugin would be nice.

just a note: take a look at the maya 6.5 bonus tools. The new unfold plugin works on the same principles. Just unfolded a rather complex head in less than a half hour using it. A question for denis F. How does Unfold 3D compare to this and houdini's unfold ?

Very interesting software.

Also, I noticed that the prices start from 165 euros .

Hello Lorecanth,

As we are UNFOLD3D providers, I believe that we are not the right persons to make comparisons with other softwares. All that I may say is that UNFOLD3D is just something else, never seen before (have you tried free Fraternaware Version ?). Just have a look to what says one of our customers on this XSI forum, and have a look to his posted work :

http://www.xsibase.com/forum/index.php?board=5;action=display;threadid=16721;start=0#msg116836 (http://www.xsibase.com/forum/index.php?board=5;action=display;threadid=16721;start=0#msg116836)

On my opinion, this is better than anything I could say.

Regards,

Denis F.
