Finally! I was a bit burned Friday so I decided to take Saturday/Sunday off, the weather is pretty horrible here: hot and wet. Which makes it difficult to get on with work.

Two shots today, one with the large padlock, and one with the shroud adapter for small locks. Enjoy 🙂

Okay I’ve finished the shroud and the locking pin, I can’t take a picture of them right now because I’m rendering textures (again). Here are a couple shots of the collar win diffuse and normal maps. I initially wanted to use a “pearl” finish on the metal, but it doesn’t really mark the normal map, all it does is make everything slightly noisy and basically hide the rest, so I decided that I would do without it.

I’m doing the final renders for the collar, shroud and pin for the hundredth time now, but after this, the last remaining piece is the large padlock itself.

The collar is almost finished! All that remains is completing the padlock adapter and the large lock, which shouldn’t take very long. I might tweak the metal a bit but I’m not touching the model anymore.

I’m sorry i should have posted at least on Thursday but i had to restart so many renders for the different blending maps (I have no idea why it took hours to render them). There is something very strange going on with render to texture and I had to work around it.

So here is the update, as it “might” look in SL (more or less), as expected the metal is different, so I’ll have to play with the settings until it looks right, also the welds look okay but somehow are not marking the normal map  properly, so that’s another thing I’m gonna have to figure out.

As a bonus, i included a couple of mask shots for those interested.

Making machined metal objects, while fun as long as it’s the high polygon model, becomes a headache when it comes to the low polygon model, mainly because hard edges and any angle over 45° become a problem with normal mapping. I’ve remade this low polygon model from scratch at least 4 times since Sunday. It’s looking “all right” but the welds are not coming out as nicely as i hoped. Part of it is probably due to how aggressively I’ve been on the triangle count. The model is remarkably efficient tho, 700 triangles, that’s less than a single sculpted prim…

But maybe it’s a little “too” low.

I also discovered that my weathering method doesn’t work with render to texture so I am going to  try to pre-render the different masks instead of doing them dynamically like I had planned, which means that all the high poly parts are going to need texture coordinates.

From really crusty “I’ve been slammed against a concrete floor for 10 years” to “almost perfect” with some light aging on the sides and a shine on the edges where most of the wear happens.

Also as a little bonus, the look of my material window…

I started the work on the low polygon model but had to scrap it because… it got confusing… In the meantime here are a few weathering tests, the idea was that the metal would be slightly burnished at the edges.

I would say it doesn’t look as horrible as I thought it would 🙂

I realized that I was going to need a lot more training to make model proper welds. I took last day to try various methods and these are what I came up with so far:

1. I like the one joining the two spheres the most, mainly because it’s concave and has circle “kind of circular” weld marks (or it could be a big glob of bondo…).
2. The tube weld is probably more realistic in term of the amount of material it’s actually using, it’s a little too straight but it should do the job too.
3. The straight weld… kind of sucks, but it’s the one I will use the most I’m afraid, I tried to make it slightly concave too, but the circular weld marks are not very convincing. (Also way too much material obviously)

I did more cleanup on the hole but I think I’ll have to redo it again, it’s just not working out really. I made a smaller padlock, which I’m happy with, and I’ve cut a notch in the flange to accommodate the smaller padlock. I also started working on the hinge/ring combo (not much really yet) and made a shroud and pin system for using more normal padlocks. I still need to work on my welds.
