Tip regarding Rim & Tyre tutorial

[runejw]

Hmm, little interest in modeling wheels ??

Anyway - to try and spark some interest - here is a rendering of a wheel-spokes model I made today using this technique - modeling one half of a spoke, the rest are rotated instances ( with every second instance scaled X=-1 )

The long part of the spoke is a birail extrusion and the center part is a cylinder.

Enjoy.


Cheers,

And here just for fun the wheelspokes on a concept car:

Yup, I know the brake discs need work... just had to put something there for now...

nice job..

the scene is interesting with the shiny beveled cubes in the back..

keep pushing the design up this..

looks a bit like a boat. the front of the hood. before the head lights is hard to make out

*edit.. thanks for the tip about instances..

Can you say something about the lighting and materials in this render? It is very nice.

Thanks for comments.

Alona:
Wheel spokes picture:
Lighting of the wheel spokes is just one HDRI (beach hdr) and the ground is a grid with lambert material where the tiles are inset and clustered polys with blue colour (0.256 0.7 0.7) and very slight reflection and bumpmap.

I think I used the standard copper for the metal.

Car picture:
Lighting is a combination of HDRI (beach.hdr) with 0 background, 0.3 reflections, 0.5 image. Then also one orange (1 0.6 0.38 ) point light to add warmth, a little under the camera at 4 o'clock (car at 10 o clock). Light has 0.75 intensity with 12 spread and 0.5 umbra.

Material of cubes is standard XSI Mat_Metals:Copper
Red paint on car is the one from http://www.xsibase.com/tools/shaders.php?detail=951
Ground is standard lambert grey.

Background is blurred photo on a grid positioned behind the cubes.

A separate dirtmap pass is multiplied to the HDRI-render pass in Paintshop Pro (paste-as layer, select Multiply in layer control) (Foundation version does not have compositing...)

* dirtmap shader http://animus.brinkster.net/stuff/plg_dirtmap/plg_dirtmap.html
* short & quick tutorial about dirtmap http://kiworld.free.fr/html_anglais/dirtmap.htm

I find that the dirtmap adds some realism (especially in connecting "floating" wheels to the ground) and generally use it at 80% strenght. Doing a gaussian blur on it before multiplying it is another tip.
