1. Re: How can I stop Photoshop CS6 from unwelding imported 3d models?
conroy Jan 24, 2013 11:33 AM (in response to Georgerocious)Adobe needs to fix the problem. There's already a couple of threads about it. Unfortunately, but quite typically, Adobe do not indicate that they intend to do something about it.
Problem importing 3D objs into CS6 extended
3D feature, when importing 3d model, unwelds polys at UV borders

Georgerocious Jan 24, 2013 2:01 PM (in response to conroy)Question to the forum, did earlier versions of photoshop extended have this problem? From what I saw of other's work, it appears not.
Can anyone please verify?

Photoshop does not, and can not do that. We do not split geometry that comes in whole.
If the geometry/mesh comes in split then use you can transform pieces. But we are not a modeler like 3D Max, and three of the four look like screen shots of 3D Max. The exception being image 61658057.png which is Photoshop.
If you don't want your mesh to split apart then dont export it as pieces, which is what you show in that 3D editor, 76040241.png for example.

The mesh was whole before import into Photoshop!!!
Is anybody testing the software? If yes, then you'd surely know that polygons within a previously seamless mesh are being unwelded from each other, along UV island boundaries, on import to Photoshop. The mesh isn't broken into separately named objects in Photoshop, but its structure is changed and unwanted seams appear in the mesh and prevent correct texturing. Splitting along UV boundaries when importing can be found in some other apps, but these apps give the user the option to do that or not!
What hope of a fix is there when you don't even understand Georgerocious's abundantly clear screenshots? He shows an exploded mesh that was a seamless mesh before import to Photoshop. He imported the pristine seamless mesh into Photoshop, exported the wrecked mesh from Photoshop then imported the wreck into Maya or Max or similar for examination and to produce the exploded image.

I understand what you are saying but the forums are lighting up for misinterpreting the issue described here.
If that is happening >>being unwelded along UV island boundaries<< we will investigate. I checked out the sphere posted on this and other threads and it does not look that way (eg broken up) in some of the 3D apps (eg Cinema 4D) I have looked at, so that could mean any number of things are going on.
I would like to know what apps, aside from Maya are seeing this. I'll check 3D Max tomorrow and make my own examples and see what happens.

Your absolutely wrong response (reply #3), where you deny Photoshop has a problem that it does have, is marked correct!

It just adds insult to injury that this daniel fellow went through the trouble of finding all of the posts I made on this issue but didn't go through the trouble of actually checking the problem in photoshop.

The fact that you have no ideas worth sharing does not really surprise me. It is not an easy problem to solve for a variety of customers that are your audience. Photoshop has a very diverse community, what you think is good is not what a Photographer thinks makes sense. It's easy to complain about on a forum, and if it is constructive that is fine but you seem to enjoy just complaining or insulting.
>> I've been waiting 5 months for one simple bug-fix<< I don't know when this was first reported and it's unfortunate we missed that (oh yeah we are human too) but we do have mechanism's (Bug reports on feedback.photoshop.com) that reach us directly, some of us patrol the forums but we cannot do that full time and ship a product.

You say it's a fact that I have no ideas worth sharing. You are damned cheeky to a customer who helps pay your salary, lad. What's your problem? Embarrassed by your inept "investigation" of a reported problem? Anyway, how on earth would you know anything about my ideas or their worth?

What? Not easy to solve? Just don't unweld the polygons! Not unwelding is easier than unwelding, surely

That sounds ridiculous.

You're completely mistaken again.
I wasn't talking about the problem in this thread. (Which you've denied exists, then admitted exists and will be fixed, and then suggested to be a design decision on behalf of photographers.)
I said "one bug" not "this bug".
The bug which still isn't fixed after 5 months, despite being acknowledged by Adobe, is one that was introduced by the OS X version of the 13.0.1 update. It makes the 3D rendering almost useless for OS X users and did not exist when customers paid $300 for the 3D rendering.

Fair enough, but by reading the linked threads in reply #1, you should have seen that the problem is one of unwelding at UV boundaries and not the breaking of a mesh into multiple objects.
Regardless of Adobe's intention to prevent the unwelding in future, the cracked 3D texture painting at UV boundaries needs to be addressed. The problem is well-known and other 3D painting software implements a solution, but since this has eluded Photoshop, I'll post a separate thread about it, later.

26. Re: How can I stop Photoshop CS6 from unwelding imported 3d models?
conroy Feb 1, 2013 5:34 PM (in response to Georgerocious)George, remember your problem initially was cracks in the textures painted in Photoshop. Here's your screenshot:
Preventing Ps from unwelding on export is itself going to make no difference to that. The unwelding of the mesh becomes irrelevant, anyway, if you don't use the exported mesh and simply use the created textures on your original mesh in Maya or other app, as pointed out in one of your other threads.
The cracked texturing is mainly a result of Ps neglecting to bleed paint into a region of a few pixels width outside each UV island. (At some UV borders there seems to be a pixel of bleed but that's possibly an unintentional side-effect of some calculation.) I said "mainly" because some pixels inside a UV border can fail to be correctly painted, too.

27. Re: How can I stop Photoshop CS6 from unwelding imported 3d models?
Georgerocious Feb 1, 2013 7:03 PM (in response to conroy)Hmm, I hope I didn't miscommunicate, but to clarify, Photoshop appears to unweld polys as it imports a 3d model. Judging from video of previous versions of Photoshop where it did not do that, It appears that it would not have this issue but I'm speculating until the patch is live.
I can tell you right now that when I put in the obj from photoshop that is broken up into Mudbox, that I get similar behavior when trying to paint over the unwelded polys. So I'm staying optimistic that once the fix is in, then everything will work perfect.

No, that's wrong!
Daniel has explained that the unwelding happens on export, not import.
The screenshot of yours that I posted above is cracking in the texturing of your welded mesh inside Photoshop before export.
I can asssure you that Photoshop neglects to allow for the cracking effect of not painting a region on the outside of a UV border. Preventing the unwelding on export will not change that.

30. Re: How can I stop Photoshop CS6 from unwelding imported 3d models?
conroy Feb 2, 2013 4:58 AM (in response to conroy)If you completely cover your (still welded) sphere with black paint in Photoshop then the resulting texture is this:
Here is the UV mesh overlayed to show that the paint does not spread beyond the UV boundaries:
Paint is required beyond the boundaries. Otherwise, when the texture is interpolated for rendering (high quality rendering or OpenGL display rendering) on the model, unpainted pixels can be "pulled in" at boundaries, creating a cracked appearance.
The following texture will not be rendered with cracks because the black paint bleeds beyond the borders. (Obviously, the UV mesh lines wouldn't be in the real texture and are there only to illustrate the bleed.)

An unwelded mesh may make painting problematic in Mudbox. (I don't know whether it does or doesn't since I don't use Mudbox). I initially thought the unwelding was happening on import to Photoshop and was responsible for Photoshop's painting problem.
However, the problematic painting in Photoshop happens with a mesh while it is still welded. Photoshop is only unwelding when exporting. The unwelding is not implicated in the painting problems that occur before export.
