Title: poweRgear
Post by: Chad Holton on September 10, 2010, 12:40:52 PM
This particular gearbox was designed in the early 50's - I had modeled it recently and thought I would slap it into KeyShot. Comments and critiques are welcome. Thanks for looking!

Amazing!

There you go again, showing off your great "Painted Cast Iron" texture!  Question- is the end face of the shaft geometry or an applied material?  The Cholton stamped on it is a great touch- thanks as always for sharing.

Fake.  It's a photo  ;)

-Thanks, Egon!
-Thanks, Bill! The shaft end face is an applied material. It's one I had made a while back - I thought I would add some chucking marks to it for fun. I'd be happy to share if anyone is interested.
-Thanks, Ed! That's one of the best compliments one can give.  ;)
-Thanks, keyshot!

There are a couple things that I still want to fix with this one, the almost invisible input shaft is one... stay tuned!

Yes I would be interested in trying out the materials on a test assemblies of mine.  The metal looks great.  What HDRI are you using?   Yeah I would love to try out the (I guessing) Orange peel bump-mapped metal!?

This is so real, I broke my toe when I dropped the printoff.

That is really, really nice! A simple model but stunning rendering.
I'd be interested in trying the materials, too!

Oh oh!  Do I detect a stress crack on the shaft, emmanating from the left corner of the keyway?

Really, really good. Already twittered it.

-Thanks, Richman! The environment is called studio24 and the bumpmap for the cast areas is the stock cast_iron_bump.jpg from the KeyShot library. I'll post a screenshot of the settings for these.
-Ha! Thanks, NormanHadley!
-Thanks, jhiker! It was fairly simple to model too. Don't tell anyone - but there is no output gear inside which makes it an infinity:1 ratio.  :D
-Hey Bill. That's no stress crack - I was trying to mimic a chucking mark (or whatever it's called) on the end of the shaft I see every now and then around here.
-Thanks, Thomas! And thanks for the tweet!

I have attached the settings for the major materials used. The cast iron is using a metallic paint. The swirly is what is used for the shaft end along with the chucking marks and "CHOLTON". I know it's not the best looking texture out there, but it works... Let me know if there's another material you're curious about.

Here's another view of it.

This is excellent - except for one thing: the HDRI. I don't think that the image you are using is an actual HDRI. The brightness is waaaaaay to high for an HDRI. It may just be a jpeg, or more generic, an 8 bit image?
Title: Re: poweRgear
Post by: Chad Holton on September 13, 2010, 05:38:32 PM
Thanks, Thomas! The HDRI was set that high to blow out the ground plane to give it the effect you see. I had to crank all the other colors down too.  It did make the input shaft almost vanish in the first image. Probably not the most conventional way to work with an environment, but I like the way it turned out.

BTW - Did those KS cookies taste as good as they looked?

abolutely stunning!
can someone give me some more details and hints on how to:
- set up exactly this environment (with lightnings)
- the reflection on the floor
- every setting for the metall on the shaft and case  (roughness and so on)

I've showed it to some co-workers and they're amazed as well.

Thank you, paul!  :) :) :)

I'll attach the environment used below (it was a freebie) and the settings for it are on the first page along with the cast iron settings.

The floor is a separate plane brought in and uses the stainless steel material. The shafts are made of stainless steel as well with the "swirly" bump map on the shaft end. I really cranked up the brightness to give the effect you see, so you will have to make your other materials really dark. I want to note that this is straight out of KeyShot with no editing.

Hope this helps. Let me know if you have any other questions.

Chad

almost done
but don't get it work to vanish the floor (seperate plane) into the white environment.
I've attached a shot from cad and my first try (without your settings of course)

Great start.

Try rotating your environment around 180 degrees and crank the brightness up and adjust the gamma also to your liking. The poweRgear unit is being viewed from the dark side.

Also, add a chamfer or radius to every sharp corner, but not a huge value unless it is huge in reality.

well, i don't need the pic anymore, but here is your bump map in action!
a bit aslope but whatever  ;D
btw, it's the lowest settings (fast) possible!

Very nice ...

Glad you tried out the swirly bump map. I need to create a better version of it, that one I spent about 30 seconds creating. If you decide to finish out the whole box, please post it!
