Weld Seams
polycounter lvl 18
Anyone got any neat tricks, tips, work flow ideas for creating weld seams for a high poly model?

- Reset the back/foreground color to B/W
- Create a new layer, set it to overlay
- Take a hard brush
- Turn on color dynamics
Set the back/foreground jitter to 20%
Sat jitter to 10%
Brightness Jitter 25%
- Turn on Scattering
Set both Axes to 50%
- Turn on Noise
Sometimes (and of course you want to be careful with this) it can help to apply bevel/emboss to the weld layer to give it a little depth and shadows. For obvious reasons this isn't a great idea, and it can help to go in and hand paint highlights and shadows based on the arrangement of your UV pieces.
Depending on the workflow, its not too hard apply the B/W welds to a normal map.

Oh and its in Czech too, but pretty straight forward
Side note kinda funny to see someone else using that for welds too... Yeah it makes backwards welds, but i bet if you saved out your welds as separate layer you could invert the channels and get the inverted welds like you see some times.
This was the method I was going to post but thought it would be too obvious
If I have two pieces like this, and the UVs are going to be separated
1) simply painting it in Photoshop obviously wouldn't work, because the weld normals wouldn't be accurate across both UV chunks.
2) Doing it with modeling should generate correct normal maps, but the color and spec would likely be incorrect, and therefore cause a seam split.
So how would you tackle this same process with two elements that would have separated UV chunks? The examples you guys have shown look great in the modeling phase, but the UV's and texturing of something like this are were I get confused, particularly in the example of multiple cylinders intersecting or other odd shapes that will require unique UVs.
or i create shape from edge loop and then use the paint deform thing to make it blobby. i guess noise would work too.
- Create a small floating weld plane that sits at 45 degree angle where the pieces meet.
- Fuse the pieces together so there won't be a UV seam.
- Put the weld on one plane or the other.
- Is there a reason both planes need to clip into each other? Can you place one piece on the surface, and flare out a row of polys to put the weld on?
