Backhoe Contribution – duerer – Wheels / Rear Axle

[Ingmar Franz]

You’re absolutely right, @spikeyxxx , with being very carefull with vertex weights. I’m currently experimenting a lot in order to avoid any steps due to shrinkwrapping or, if I can’t (easily) avoid them, bring me at least into a good position for final polishing after having applied the modifiers.

The gearbox consists now only of quads, but the shrinkwrapping still needs some tweaking, especially at the yellow pads on both sides of the gearbox:

And this is my rear axle now with the all-quads gearbox:

This is now one continuous all-quads-mesh:

Another part connected to the left:

Only the gearbox side ring still has  to be connected

That is looking really good @duerer! Both the shape and the topology.

I love this slight ‘bulge’ in this ‘new’ part when it goes from ‘square’ to circular; gives it this almost organic look of cast iron.

Thanks a lot, @spikeyxxx 😀!

 I had to dissolve many edges at the green-blue part on the left side and bring the circular shape back to perfect circles with “Loop Tools”. The edges (marked with a more saturated yellow) are beveled. I duplicated one edge area and used it as snapping target for the resting three in order to get an even look.

At the magenta bolts holder, I made the edge loops run down straight from the holes to the axle bottom instead of directing them into the corners nearby because this caused a lot of edge stretching so that some faces were overlapping which was clearly visible. 

The holding edges at the corners  of prodtruding parts are always a challenge, escpecially when they run into curved surfaces. I have a mix of solutions which all aren’t 100 % perfect (I don’t know whether this is possible at all?) but some slight pinching is only visible if you come very close and  I can at least live with it. Maybe you can have a look at it when I post my finished file?

How true and I think you solved that quite beautifully!

Here’s an example of what I did:

When using one of the extreme Matcaps you can see some stretching, not even a lot. But now look at the mess I made of this in Edit Mode:

I’ll be happy to take a look when you’re finished, but what you’ve got so far looks great, I can tell that from the screenshots already.

Whoah.

I use the “Shrinkwrap Modifier” in order to project the outline of the cutting surface of the part that I want to connect to an object and do the same with a scaled up version of that outline as holding edge loop.  Round objects are easier to connect since they don’t cause as much stretching as objects with angular cutting sufaces.

I added recesses for the gearbox bolt nuts, but it’s not yet all quads:

[spikeyxxx]

Didn’t notice this before, but there is some pinching here: 

might be easy to solve, by merging those three close-together edge loops at the bottom. 

Something like this: 

and:

Might not work in your case, but it’s worth a try.

Don’t stress out too much if you can’t solve it, with the right shader (dirty, greasy, damaged, painted iron) you’ll be able to hide it;)

Thank you, @spikeyxxx, for the hint 😀!

[Ingmar Franz]

And it worked very well (!) 😀:

Now, the gearbox side rings and the green-blue part are all quads and without any 6-poles:

The green-blue element to the right of the gearbox is a mirrored in global Y duplicate of its axle left side counterpart.
