Creating welding seams in Maya

Are there any default tools or scripts to create harsh welding seam hi-poly geometry for normal map baking?

Anything of this kind

This is a procedural method for dirt and dents on geometry. This might give you a starting point.

Thanks, jgibz! but I actually need some kind of zbrush sculpting - not a rendered result(

Is there any suppressing reasons why you can't create the seams procedurally ?
Since your goal is obviously to bake the welding seam to a normal map and not to use the geometry you're looking after ?


do your stuff in maya and bake it out and then use either this :

or this:

to convert your baked output to a normal map

how'd that sound like ?

unfortunately, the pipeline requires me to suffer. The hipoly stage must be in geometry. Only 2 options: zbrush and 3dsmax plug-in. But I only like maya....

Well this goes a bit involved and far-fetched but you could do the procedural approach as a displacement map, convert the displacement to polygons and then fine-tune with artisan tools?
Does it sound too lengthy ?

It sounds only like something I haven't done before)
Got to think about this, thank you

I would just sculpt that detail using a sculpting application then save out a high poly version for baking. I'm assuming you don't have Zbrush which is why you are looking to do it within Maya.

If you are looking for sculpting tools in Maya you can check out Joe Alters Lip Service plugin. It's mainly designed for animation/rigging but it looks like it has some of the basic functionality of Mudbox.

Alternatively you could use Blenders sculpting features which are pretty good considering it's free. Blender is fairly easy to pickup if you just want to use the odd feature. Just export your mesh to blender sculpt your seams then send back to Maya as a high polymesh.

Get a life: get Sculptris!

You can do this in many other ways inside maya as well.
DisplaceD plugin for maya if you have older version,
http://www.hajimenakamura.com/hajim...displaceD.shtml
or try this:

There is at least one more plugin which does sort of same thing...

Also in maya 2014 you can build a shape straight out of fluids.
Fluids you can then just convert back to polygons and there you go...
Also check new mootzoid plugin, you can do this thing in few minutes too...
