modeling a welded tube?
show user profile  Error404
I seem to remember years back someone posted a clever way (maxscript maybe?) to model welds on tubing joints (like a bicycle frame, or a roll cage, or whatever), something that was somewhat automated.

Anyone remember what that was, or have any new ideas? Trying to not model the weld by hand and place it on all the joints, wondering if there's a more automated way to do this.

Ideally, any intersection would have a weld bead connecting the two objects. Be they tubes, or whatever. I used to just model them by hand, but I don't have patience for that anymore, haha

On the simplest example, it could be not much more than a smooth bevel:

On a more complex example, it could be a "ripple" looking weld, or a "stack of dimes" weld that has regular ripples to it. -

Are you talking in 3D or real? If it's 3D I can show you how they do it in games.

Yea, sorry I mean in 3dsMax.

I was thinking maybe metaballs somehow? I'd like to do it with geometry if possible, instead of purely a bump map or displacement. -

I'll do a couple of screenshots for the technique I know. The results are good. In a nutshell, you use edge extrusion and make a ring around the intersections, unwrap it and add a good normal map and you're sorted. The end result's better than it sounds... hang on... making screenshots...

Yeah, welder looks good. I'd definitely go that route if you have to do a lot of them, else, if it's a couple, you can do it manually.

Then again, if it's all high poly, just use zbrush.

Modo / Meshfusion is a nice way to get base joins, then bump and normal till your happy...this was for a chrome lighting stand, no ugly welds needed.

A free script that builds high poly welds like that, which could be later turned into normal maps as mentioned above. Works quickly, and fairly well.

Thanks for all the ideas fellas.

I'll hopefully have some test renders soon :) -

Yea, I've been messing with it. It's got the level of automation that I can live with. I used to have patience to do little stuff like this, but now my time is more precious :D -
