Getting a pattern on a curved surface (tube) with the stamp tool

Hello folks, I hope everyone is ok around here and not too heavily affected by any of the numerous actual crises like heat waves, wildfires, fuel prices and gas shortages and what not …

My problem is: I need to get a pattern I have created an Alpha for on a bent surface. The Alpha is straight; the bent surface is a loop. I know stamps follow curved surfaces, for example the outside of a cylinder. How can I get the stamp to follow the loop? I created the loop with the tube tool.

I have included an image of the problematic model. The pattern that is stamped on the inactive (straight) part of the scene needs to go on the loop.

Thanks a lot for any help and have a good time

This is something that drives me nuts. The stamps and different tools project the alpha along the view and not the surface of the object. To my knowledge, there’s no way to stamp the object surface is such a way as to wrap it around :slightly_frowning_face:

Maybe someone else knows of a way but not sure you can do it.

This is the closest Adam did for you @RogerRoger. Where was the original discussion? Anyway, just a workaround, if I am remembering correct.

There’s two where I’ve discussed it a little.

And the other one I’ll post after I find it…

I was able to make the ice cream cone work but not the mask texture in the above link. Possibly using a combo of radial symmetry and stamp tiling may get you close but not the best result.

@RogerRoger and @knacki: Thank you very much, guys, for reacting to my question so quickly. I’ll go read the other discussions @RogerRoger sent a link to and see if I am getting any wiser. Thanks again for helping me out - this forum is really great!

What if you split the model in half with masking, than create a new layer…then use the alpha, invert the mask and use it again with the other half.

At the end you delete the Mask and use the “Delete Layer”-Tool with less than 10% intensity and erase it at the transitions?

The advantage is that the object is not destroyed and you only work on the layer.

Thank you so much, everybody! This forum is really great.

Alas, none of the solutions quite worked with my model. As it is a rather flat braid on a victorian cavalry officer’s jacket, I think I’ll go a different way, make myself an alpha, stamp it on a flat primitive and cut out the form. If you want to I’ll show the result here.

Thanks again, have a good time,
Richard

It would be nice if you show your result here.
Just out of curiosity, do you want to do something like that ?

I need to get these horizontal braids on the jacket of my model, which is a bust depicting a British hussar from the mid-1850s. The image is rather bad, I fear. I hope it shows what I want to achieve.

Actually, your attempt comes rather close! Congratulations! How did you do it?

You need an alpha with a single segment of the pattern, like this. The center of the alpha may need to be off-center so that it turns nicely in the curves.
Set the stroke spacing and use the tool in DOT mode …+ symmetry

Meanwhile I am convinced that an alpha will give you a quick and good result, depending on quality of your reference picture you will turn into an alpha.
My quick test after adding a few spheres as knobs.

You can even extract the layer to ne geometry.

But now it’s about finding a high resolution picture you can turn into an alpha,
I found some on Etsy, but they are not good enough.
Or use them as base to draw your own alpha. Again, I guess that is easier than sculpting - and with a very good result.

@Holger, @knacki: Many thanks for your suggestions and for spending your time with my problem! After some experimenting, I think that knacki’s idea with creating extra alphas for the different strips of braid is what provides the easiest workflow and best results. I made some rough sketches on Procreate and turned them into alphas which I then stamped (experimentally) on an early version of my hussar’s jacket. This is only a test, done quick and dirty, but I think it shows that this method has potential.

Thanks again to everybody for dedicating your skills to my question. It’s really great to be a member of this forum. I hope I will have gained enough experience with Nomad soon to lend my time to another member’s problem and so give something back to the group.

Cool!
Don’t forget to use layers!
This way you have plenty of options.

  1. You can use the DelLayer brush for adjustments
  2. You can go into layer menu (three dots on right) and use extract to generate a new mesh, or in Nomad 1.66 you can one tap to mask what is changed with layer.

Super cool for your purpose.

Edit: Remeber that you can paint same time while applying alpha. My example is one stroke only :grinning:

It’s a small feature but really powerful & will be getting a lot of use from me!

Yes, storing masks, one use it as Polygroups replacement, Together with extract it is a whole new world of options.
