Subject: Cylindrical Mapping a Tire

As in creating the tread. I've tried everything I can think of to map this correctly w/out success. Any ideas on how this can be made to work? Thanks in advance,

Chipp

Have you tried creating the tyre as a boolean? A cylinder with a cylinder cutting the middle out. That way if it was mapped cylindrically then it should do the tread no problem. Just an idea.

Yeah, but then I can't get the nice radius. Currently, I'm using the letter 'o' to create the tire. Strange, this should be simple.

Flip the bitmap 90 degrees and set the mapping mode to faces

Thanks David, That's almost there, but it wraps the texture onto the sides of the tire. So, it's not a true cylindrical map. I'm wondering if you know of a way to do this in the function editor? IOW, is it possible to 'flip' a texture's orientation using some sort of combination of tiles? Thanks for your helping out. best, Chipp

Chipp, Its possible but it would take a lot of tweaking around. Why not just UV Map the tire by uing the free version of UV Mapper.

Hi Dave, I've got the registered version of UV Mapper, and thought to do it, but am preparing a quick and dirty tire tutorial and didn't want to get to that. I've figured out a way to do it using a SINE WAVE generator, but was still interested in how this problem could be solved. It's really a simple issue, and I'm not sure I understand why Vue has made it so difficult? Other 3D programs I've used allow for multiple axis cylindrical mapping, why doesn't VUE?

I messed around a bit with a cylinder (didn't have a tire shape). Got this.

Used a 256x256 white image with black vertical stripes in center only (see the function pix):

Had to flip image 90 degrees for tex and bump. Had to turn tex image "negative" in material editor to get side of 'tire' to come out white instead of black.

Hi Jim, Yes, it will map correctly on a cylinder primitive, but try using a text model of the character 'o'. That's the problem! :-)

 


jc ( ) posted Wed, 01 March 2006 at 3:34 AM

Yes, it looks to me like the UV mapping is wrong on the text letter "O" for what you want to do, Chipp. Have not exported it and checked in a UV mapper though. Way past my bedtime here, lol.

Here's how I accomplished this using procedural settings. But, I'm still at a loss on how to do this using a mapped picture. I used a clip filter to tighten up the noise filter. Use_Nois.jpg

Here's the final result. The idea was to make a tire with rims completely from text objects (no booleans).

Not sure if anyone's figured this out, but I did get a reply from support at e-on with the correct solution: "- [Effects tab] Global transformation, check Rotation, then open the editor, and set a 90 rotation on the X axis." Didn't even know that was available!

Thanks for checking Chipp! That's sure "one for the books".
