Speed Modelling Challenge #169 Keys
*************************************************

Rules:

1. Every week there will be a subject for you to model along with a time limit. You should spend no longer than the allocated time, then post a render of your model. As in most challenges like this, your honesty on modeling times is essential. How you interpret the brief is up to you as long as the final model conforms to what is asked for.
2. Post a wire-frame and a render at 800x600 or larger.
3. LightWave must be used for modeling. 3rd party Plug ins are allowed.
4. You can enter as many times as you like, posting each in this thread. If you run over the time, the model can still be posted but won't be subject to the judging.
5. Time spent on texturing, setting up a scene for a render and rendering is not included in the allocated period.
6. The winner is judged by the challenge starter and the prize is to set up the challenge after next week's .
*************************************************

This week's topic is: Keys

Old, new-modern, with magnets, batteries or without, wireless, for the house, office, cars or whatever.
I'm far away, so see ya on Wednesday.
Have fun!


Time limit: 60min.
Deadline: Wed. 2nd May 2012. 22:00 G.M.T.

This key is a high security future key. It's powered by magnetic induction from the lock itself. The blue LED's operate like IR remotes sending a high speed pulse sequence (each LED has a different sequence) The inner LED's are ultraviolet and sent a very specific lightwave that must match exactly.

The handle is held between the index finger and thumb and reads the users DNA and pulse. Infinitely programable in a way that your neighbor can give your key access to his home for certain dates while he is on vacation so you can feed his dog and water the plants. After the date passes your key no longer opens his door.

sublimationman: Nice modeling and don't forget to patent it.:)

Haven't done one of these in a while, and my lazy surfacing supports that fact. Modeling was done in 40 minutes.

I wonder if this thread should be locked?

Overtime with this one. It was all going so well and then I clicked on boolean. :D

Oh... Here's the normal map if anyone want it. Cheers!

wait, you modeled it w/Boolean, and then rendered using the resulting normal map?

(I was making a similar key, and found it surprisingly difficult to get the surfacing to Smooth correctly.)

Wires?

That's right. :thumbsup: I created a key 'blank' then used boolean to grind out the serrated key edge. And then I spent an hour just merging points and cutting loops.

Here you go.

Nice. An hour-- I don't feel so bad about my late tussles with Rounder. :beerchug:

What did you use to generate the normal map? TNX! :thumbsup:

You can see after the boolean it just all fell apart.

Sorry if I'm being thick here (and I have a sneaking suspicion I've been told this before)(and the network grab is too small to read)(and there's no "if" at all here), but: so, you made a mesh displacement with the bitmap pictured, saved it as a normal map, and reloaded for use as a normal map???

Thanks.

Sort of. The normal map was generated with actual geometry. ie it was modeled. Then rendered with the Matcap normal map surface and the orthographic camera. Sounds strange?

Well...

1. This was a texture issue. I was happy with the key model and had move onto the texture stage. I tried to create the normal map in gimp, but LW is so much better at creating text and circles, I couldn't do it in gimp.

2. I now have the normal map, and can use it wherever.

3. I was going to use bullet to drop 20 or so keys onto a ground plane. The normal map would speed up the simulation.

4. I'm trying to learn. I mean what's the best way to create a normal map. If you use the photo to normal map filters, your normal map always looks like crap. :D

Thanks for the interest.

It's all a new world to me. :\ Thanks for the explication!

Ha! I was going to do the exact same thing, but my key sucked.

A bunch of old keys (well, two repeated anyway :hey:.)
20 minutes modelling.......................

I'm wondering let say you modeled your key in lightwave within the time limit and all. But then you take that key into Zbrush to do the details render out a normal map and apply that to your key? Would that be considered cheating? I mean I think it's been established that using Displacement and Normal maps are okay in the competitions. And since you would only be using Zbrush for the normal map or displacement map creation it could be counted as textureing work and get a better final looking model. Then again if the subject one week was something Organic,you could just create a high density mesh ball in lightwave in about 10seconds. Then do all the work in Zbrush and export your maps. This way you could take hours and hours to do the model.

xswampyx, that is one krufty key there.

++
in a previous post you mention the "matcap" node. I don't find that in the LW surfacing dox, is it a 3rd party node?

Thanks!

It's from here. http://forums.newtek.com/showthread.php?t=115614 Go to the last surface posted to get the automatic one.

Then render using this texture. remember to turn off all the lights, set luminosity to 100 and the colourspace of your texture to linear.

XswampyX - thanks for all the info. I'm going to have to study that thread because, honestly, at first glance..... all over my head. ;D
Colorspace = linear? Can I do that in 9.6.1?

But my question here is really about your last key. Great crumbly bits:thumbsup:. Am I right to assume that it's geometry displacement (in object properties)? And if so, in order to get such small bits like that to displace, one needs to really crank up the render subpatch level.... so I see your original mesh, what was the final render sub-p value??

Or am I thinking about this all wrong?

Iain - awesome second render.

Nice entries guys!

Still on the road so I will be quick.

sublimationman: Very high protection. :) Nice and clean model, hope it won't be pricey!

Rabbitpenny: Nice lock, nice key, nice modeling, nice texturing!

BlueApple: Clean spiral/circled key modeling! Good result for 40min!

XswampyX: Good render. Classic key! Nice mini tutorial. Forget the boolean operation. :D Second key is very bacteri-cious. Interesting.

Iain: Clean model, nice texturing, super render!

JoePoe: I like your model and your render but you are way late, way over, way tired. Sorry, appreciate your effort, keep up!

The winner is: Rabbitpenny!

Thanks again for participating!

Well done Rabbitpenny, lovely wires there. :thumbsup:

Ref the Matcap... You don't have to understand it to use it. :)

Sub patch level on the key is only 12.

Cheers.

XswampyX: Thanks for the kind words. And thanks for the generous supply of information you supply to the forum.
