Enamel Pin Challenge

Post by tuna57 » Sat Jul 13, 2019 12:02 am

Inspired by the "Futurama" pin posted by jxmoss. So here's the deal .... model up a "lapel pin" with a "space" type theme and get to rendering.
The modeling is a bit of a challenge due to the finished size of the pin :) . Knocked this model out , suppose you can call it a shooting star ? Finished model is only about 1 1/2" across. It does have a pin bach with the little closer doodad thing on the back.....

Rendered on Easy 9, 75 passes, 1800 px. x 1534px. Took about 2 1/2 hrs on the iMac. Final image had minor adjustment in the Mac preview window.

Now for some model set up details. The silver is a Deep Editor material, Ashikhmin_MLT - silver . The ground form shiny plastic template. The three colors on the pin are Advanced Reflection - Gloss Tile with the min. shine dialed up to 250.
Lit the scene with an HDRI studio set up.

I find these small things pretty challenging. :! . About wore out the Exploration Render testing different light set ups. Not real happy with the shine on the "enamel" parts of the pins. Tried different templates and adjusting the shine range. Couldn't seem to find the sweet spot... either a little flat looking or blowing out real bad :wall: . Further experiments as time allows. :^:

Hey Tuna, Looking very nice! :clap:
I hope everyone will right-click image and view at original size. :^:

I think you can see on real enamel lapel pins that the enamel coating will "cup" or make a "meniscus" at the edges where it touches the metal sides. If this were carefully modeled, I think the reflections would look much more realistic as enamel.

Thanks Fletch. Appreciate the comment about running a bevel on the enamel side..... funny you mentioned it as I thought about doing it and didn't because was guessing it wouldn't make a very big difference at the size this thing is.... well going to find out .... fix the model and ran the bevel on the enamel side and have a render cooking now.

Thanks Mike. Looking forward to seeing what you come up with. Your right it's as much a modeling challenge
( at least for me ) as a rendering challenge. Had to work all the bevels on a copy that was scaled up 2000x . Still had to do a little repair here and there even working at that scale. Good luck with your pin :^: .
