Wow, that's awesome! Mind if I ask how you placed the tire nubs so precisely and regularly all around the wheel?

cheffey

That is awesome, great work in progess shots.
I would also like to know how to place the knobbies on tires like that, is there a tutorial around here?
Coming along nicely though.

rsw

Similar method to this here, although a little bit more complicated, due to the curved tyre profile. If I have time I might explain it in more detail later.

Not really had much time to work on this recently, but here's part of the frame at the moment:

another quick update to this...
Trying to create the welded joint between the two sections of the frame, not quite sure if i'm happy with it just yet though...

Holy Cow, dude. Those welds rock! I assume you don't like how the lines pop compared to the rest of the line work. I'm just marveling at the detail. Beautiful stuff.

I'd love to know your technique for creating those welds. I have some ideas on how to do it, but you seem to have perfected them. I'd love to put some welds on some of my cars models (for close up renders).

marked001

aw man.... that's dedication! haha.. i think that looks good for the weld.. maybe twice as many divisions on the face of the weld? looks awesome though..

CraigD

Yeah! Those welds are amazing! Obviously an aluminum frame design with that nice "dime-weld" pattern!

Really great work!

Cheers,

Thanks for the comments...

Heres a quick (simplified) run through of what I did.
Note: you need SoapSkinBubble installed for this.
(click on the images for a larger view)

I've just used a simple cylinder and a flat plane to show you but the principle should be the same for any shape.

create the outer edges of the weld
Draw arcs between the outer edges of the weld (you probably only need 6 segments at most for this)
Select the edges of one 'weld' and click the creat skin button (the vcb will control the number of divisions for the skin - i chose 5 or 6)
Once the skin has been created, enter the group and soften all the edges.
Exit the group and click the Generate soap bubble button - the vcb control the 'pressure' - try out a few different values to see which works best - I chose about 300.
Repeat 3-5 until you've gone all the way around the joint. (in this instance the weld could have simply been rotated and copied around the cylinder to complete the weld, but for more complicated shapes this obviously won't work, as each part of the weld could be a different shape)

Just another thought...

Does it look better with a texture applied to the weld...

This is such nice modelling Richard, welldone.

It would be nice to place this weld tutorial you created over in the SU Tutorials Forum - it's a very good tut you created.

Thanks! Tutorial created in the tutorials forum.

Totally awesome. I've spent a lot of time looking at bicycles and you are hitting everything right on. Of course, you can only get a reflection on a tire if you use ArmourAll on it and that's not good for the rubber.

Those welds are masterful, especially making them slightly inconsistent to show that it is hand work. Wow.

dylan

Thanks Richard

Continuing to make slow but steady progress with this...

I'm trying not to think about what the poly count and file size of this might be once its complete!

dylan

Looking great. You have certainly got those welds perfected now

monsterzero

Thanks for the tutorial, Richard! This will add a lot to my vehicles!

I'm going to have to do the first few again though, as they don't look as good as the most recent ones, and even though I've got the technique down to a fine art, its still quite time consuming.

Hey Richard, I've been following your most excellent work! I have a question on your workflow; I see you are using groups for each weld...why not use components? With a component, the work you do on one, would be duplicated on many, leading to much quicker work. For randomness, you could create three or four weld components, and then copy them in a selectively random pattern.

If I understand your workflow properly, this could reduce some time. Just a thought!

Cheers,

CraigD

Usually I would use components, but most of the welded joints are between two non-uniform shapes joined at odd angles which means that non of the individual welds are the same. If I was using a cyclinder and flat surafce for example (as in my brief tuturial) I would use components as the joint is uniform all the way around, but unfortunatly there are very few instances on this model where that occurs.
