Motorbikes

Motorbikes I've modelled in Cheetah 3D. The head, spokes and the
front fender of the HRC racer and the Vincent engine have been developed
from polygon models found on the web.

May be that, sooner or later, I will also learn the way to model some
half-decent fairing... :-]

modeling and lightning - all great !

now you need a driver to start an animation (helmets are easier than faces

)

I think you're still using some specular. The tires, for instance. Get rid of specular from every texture, replacing it with subtle, blurred reflections, and you'll be amazed at the results (looks particularly good on mostly dull objects like tires).

Looks great, nice work! I agree with podperson, there should not be specular on the tires. Keep up the good work!:smile:

This is very good! Keep up the good work! :icon_thumbup:

I'm not sure about motorbike tyres and how reflective of light they are!

Very nice models.

Made some experiments on tires with specular and reflection settings
but I'm still not satisfied with the results.
Keep in mind that brand new tires sometimes can have a semi-glossy finish.
Back to the drawing board :-] , thanks for the suggestions.

Try increasing the specular width for the tires.:wink:

podperson · May 1, 2008

I'm not saying tires shouldn't be glossy, I'm saying don't use specular to simulate gloss. Use blurred reflection.

Everything in this scene has specular set to black, including the tires. (From this thread: http://www.cheetah3d.de/forum/showthread.php?t=2228)

Specular highlights always look fake and wrong. They're simply faux light source reflections, but since they're based on the material and not the light (so if your material settings change, every "reflection" changes, whether it's supposed to be a big fat light source or a small hard one), they never look right, even if your scene contains nothing except light sources.

Here's the scene file if you want to see how the textures were built:

Hi,
very nice motorbikes. Great job :icon_thumbup: But you used a too low .jpg compression setting. So many jpg artifacts were introduced in your images.

Compressing a 1024x768 image into a 64kB image file is just demanding to much form the jpg algorithm. :wink:

Bye,
Martin

I think they're all great!

-Slicks are shiny but they're only that colour with a bit of wear.

Here's an option, tyre tread. Feel free to use it, I've cut it in half because the file was too big so just mirror it.

... just in case anyone is wondering. Mirror it twice and rotate the other half so the tread pattern is consistent.

meshpig · May 3, 2008

... Does that zip file work BTW??? Anyone?

If not try this

Am I dreaming or what? Just when I was trying to figure out a way
to add a tread to the tires here it is, a racing compound, hi-performance,
sticky, rubber! Et voilà, a "Meshpigstone" racing tire!
Thanks Meshpig, with the help of the, slightly tweaked, settings suggested
by podperson it's almost perfect. (HDRI map not yet defined)

Thanks again guys.

@ Martin, this time I've used a slightly higher compression setting.

Ha! Hey, no problem. Looking good!

A few weeks later...

The 4 cyl. is still under construction. I don't like the silhouette of the crankcase of the engine,
don't like the flow of the shapes of the gas tank etc, etc, aaaaargh!

podperson · Jun 18, 2008

Mmmmm now if only I could jack one and tool around Liberty City on it...

xyzr · Aug 22, 2008

Outdated 250MXer(s) never die. Thanks to Cheetah 3d (and with some help from Wings 3D) they become ... roadracers.

Tartiflette · Aug 22, 2008

Wow, that's a great motorbike collection you have there !

Would be even better in a nice environment, the models deserve it.

Keep up the good work.

Cheers,
Laurent aka Tartiflette

Hi there

Just one more ... it's supposed to be a 500 twin
