problem with break in Unwrap UVW

[behdadsoft]

Hi.

I made a model and now want to add texture to it. for do this, I create a pelt map from current made model. but when I add texture to it, it show a brake line on my model. how can fix it?

Thanks.

You cannot get rid of this "seam".  A seam is inherently part of the nature of what you are doing, you are creating the conversion needed to display a 2d image onto a 3d object.  Somewhere along the line, the texture will meet itself, and voila, the seam is born!

The challenge is to "hide" the seam.  

If you are lucky, and the user of your work will NEVER see a particular part of your object, put the seam there.

If not so lucky, and there will be views of the seams, then you may need to spend time on your 2d texture to limit the difference of the image at the seam.  A good way to do that is to take your texture and apply an "offset" (Photoshop command).  This will place the "seam" in the middle of your image.  Now, using paint tools and smudge tools, you can change how the seam looks.  This won't always suit your needs, but when it works its great.

Working with the 2d image is hard to describe, so I did a small demo.  I pretended that a texture was going to go on my object and it needed to be a gradual shift from white to red.  But I HATE the seam!  

image 1 is the file of my original image.  Simple gradient, looks nice....but the seam will look bad, see image 2 (putting two copys of image 1 side by side) for how that seam would look if the material was wrapped around a cylinder.  

image 3 is after applying horizontal "offset" in photoshop.  Gimp will surely have that capability also.

image 4 shows my effort to "soften" the "seam"....at least making the sharp line go away.

image 5 shows how the seam will look wrapping my texture now. (putting two copies of image 4 side by side)  The changes at the seam are less dramatic.

You can also try Texturing program like Substance painter for you to work better with the seam lines and paint directly over the seams to conceal them better.

Thanks guys.

Use offset and use Substance painter are good ideas.

Thank you very much for that one!

Have to say that I think it's really odd that this feature isn't present i 3ds Max.

Would be great to paint and blend seams within the Unwrap UV modifier.

Even a free program like Blender does have this blend painter feature 🙂

Hi Tne,

Its fun to realize how the world looks differently to different people.  Just because its free doesn't mean the decisions of what to include and what not to include in the program are minimal, or ideal.  Blender includes what its opensource development team chooses to put in.  Those people clearly were interested in users that couldn't own photoshop, so they built some photoshop features into the code.

Those users don't interest ADSK.

When the decisions on what to include in Max were made, there was no blender, there was no internet, and max was providing important tools that no other program offered.  In that situation, and when you are aiming at a professional marketplace, you would have been crazy to waste the resources needed to integrate functions of an existing and NON-Competing software like Adobe Photoshop.  Any pro using max would also have cad software, cam software, graphics software, rendering software, post processing software, etc.  ...max was developed for a purpose, and that purpose was NEVER to be a one application fits all for people without enough funds to develop a software pipeline.

As time moved on, some overlapping with photoshop features has occurred, but this is worthless to me, and others of my ilk and age group, imagine me wanting to change my workflow just so I could stop using my photoshop, which has been my go to for years.  LOL

Fast forward to now, ok....you must not have photoshop, and you must consider using more than one application to be annoying.  Since Blender is free, and includes everything you need including photoshop features you want, and this matters to you....why are you trying to use max?  Don't expect Max to be Blender's big brother.  The only way such a viewpoint makes sense is if you know nothing of the history.

Cheers,

Bob

Yes Photoshop...

Just meen it would be nice to have that feature to blend UVW mapping parts together. I was thinking of solving a thing with displacement that way, I didn't know that that feature didn't exist in 3ds Max I did just guess it would before starting to unwrap the cobblestone ground for my visualization project. Would have been nice to blend it a tiny bit. The round parts of cobblestone is mapped with Unwrap modifier and everything else. Simple texture and nice unwrrapping but that blend thing would have been neat.

Your post is quite fun.
