Procedural Stitches in substance painter based on input graphics

Dear people of greater knowledge

I am fairly new to the substance painter world. I would like to create an auto stitching/quilting material that is based on an input line graphic. Specifically I would like to create stitches exactly ON the input graphics. Is there a way to achieve this with substance painter? So far I have been unsuccessful.

 

Here is what I tried:

First I created an input layer with some black paint strokes in it and put an anchor point at this layer. (this will be replaced by some imported alpha texture from Photoshop or Illustrator later on)

Secondly I applied the “auto stitcher” tool in a different layer and referenced that anchor point to it. But it didn’t worked as expected. (see reference picture) It creates the stitches around the input graphics and not ON the black strokes of the graphics.

What seems to happen is that this auto-stitcher tool apparently pics up the border between the black and white rather than the actual black line from the input alpha.  

Like that, one will always end up with stitches on an offset to the input line graphics.

 

Ps: I am aware that there is substance designer to create own procedural materials that would probably be able to what I want but I don’t know a thing about that program.

Hopefully any can point me to the right direction how to do this in Painter.

Hi @PlatypusOfsorts,

 

The auto-stitcher is indeed using the input you're giving him to determine borders and add stitches to these borders. This probably won't be the solution you're looking for

 

Now, we usually recommend to use the Path tool, that is very efficient for clean stitches, but also easy to edit. However, still not procedural.

 

Currently, we don't have a filter using exactly what you're looking for, and from my point of view, you'll need to jump to Substance Designer in order to get what you want. That being said, bear in mind that procedurally determining from an external ressource a single line of stitches doesn't seem like such an easy task.

 

Best regards,

Hi Cyril.

 

Thanks for your reply. I came to the same conclusion and jumped into Substance designer for that.

I imagine the hole process like that:

1.import an svg from Illustrator into designer.

2.connect to a mask to paths node

3.use those paths to do the magic further downstream (maybe convert them to splines first)

 

But in there a similar problem arises. When entering an svg node linked to a file with only open paths in it, the “mask to path” node doesn’t pick up anything. Only when I have at least one closed path in the svg file it picks up an outline, but also unfortunately closes the open paths from end to end.

So, what could I do to get a single curve, path or spline in substance designer? Maybe give it a different kind of input file?
