Racing Rim and Tire
-
Now for something completely different. For me that is. This is part of a WIP of a model and rendering of the Nissan R89C from 1989. This will include a great deal of experimenting and learning as well as several million bug splats and autosaves. So far I think I may be getting carried away with the face count but it can be managed by merging the final parts in Kerkythea.
Thus the Nismo racing rim and Dunlop Denloc tire. The center spoke section was done with "Subdivide and Smooth" using mainly curve tangent lines or curves themselves. I divided the spokes into 5 components having a delta 36 degrees with a total of ten. It wasn't easy but I think I got it down considering there aren't many reference photos for this wheel nor the Nissan R89C.
I'm still getting some noise with my metals in Kerkythea. If anyone has the sollution to that please let me know.
Here's the model in Sketchup itself.
The font isn't exact since I wanted to finish it up this morning. That would be something to fix in the future. I created the italics by rotating the text -30 degrees on the x axis and -30 degrees on the y axis and then intersected the text onto a plane which I then reversed its rotation to be perpindicular to all axis. The rest was a matter of pulling, intersecting, etc. The brake caliper is a "prop" since the Nissan R89C used Brembo calipers.
The tire was also made with "Subdivide and Smooth."
Cheers,

this is awesome...i'm impressed... it seems to simple to build a wheel/tire.. but its so not...great modelling/great rendering cant wait to see more of the car.

It took me ages to realise one of them wasnt a photo, so id say thats a definite

Wow, that's kick ass!!
Offset, tire profile, wheel diameter for LARGE brake rotors and wheel width look a little off though.... (Second car down)

Hi Gus,
First of all let me say that this sure is a great job you done..!!

Well... When you want to render a metal material, it's very important that you're using the right material for the right render preset...
You have the Metals Phong A1, which is to be used with biased render methods and you have the Metals Ashkimish for MLT, which only should be used with the unbiased render methods...
Also...
Please be aware that the render preset and settings are very important...!!Looking forward to see an update of this...

Ditto.
And don't worry about the poly count - with a PR renderer, you really need smooth curves. -
Thanks for the comments folks.
Craig, you were right and I revised the model to reflect a 285/650R18 tire and an 18 X 11 wheel. Should be close enough now I'm hoping and the profile is much lower. The tire is about 25.5 inches in diameter.
Fred, thanks for the tip. I'll have to match my Kerkythea material with my target rendering methods. In this case being A1 metals. I also found some good information on this at the Kerkythea forum including the following regarding the metal noise

And a short video on settings

This image shows the revied wheel/tire dimensions and the new render settings. Much less noise and it actually renders faster with the settings I used from the above linked video.

This is so good that I can not explain you. So photorealistic. That polish black metal is great.
You deserved my 1 post on this forum

Thanks PJ. I think I used the black plastic material by Alex from the KT forum.
