Brass texture
I am a beginner and would like to try making a brass texture for a simple 3D build of a brass era antique car -brass lamp (in Second-Life)

I've done a Google search and have found several tutorials on making a " brushed metal surface" but nothing about brass itself. What color tools and values does one use to create a texture that looks like a nice warm, polished brass with typical brass highlights and shadows?

Is there a tutorial someone can point me to?

-thanks

Try googling "penguinpetes.com/b2evo/index.php?p=351" or directly pasting the URL in your browser.

RE: Brass texture
Thanks

At the moment I'm too sick to comprehend what I'm reading ;-)

...but I have a feeling that I may have asked the wrong question ;-)

RE: Brass texture
I'm slightly more lucid today, I hope ;-)

I want to create a smooth polished brass texture in 1024 with 512 and 256 copies to texture objects in another program

I'm mostly interested in how to get the (orange yellow) color and highlights and shadows just right for a rich polished brass, so I am currently reading about color tools and gradients in "Beginning Gimp" When I'm finished reading I'll probably have more questions ;-)

For now I have a question about the bumpmap tool. It's used for raising letters in the tutorials about metallic text but it's unclear to me whether it would be needed for a flat smooth polished brass surface?

-thanks in advance

RE: Brass texture
Sorry - I'm not describing this well. The (flat) texture will be applied to a rather curvy 3d object composed of cylindrical and toroid shapes. I can't find a close up of the lamp I want to reproduce but it's somewhat like this: http://www.antiquehotspots.com/image.asp...Height=148

Natural lighting produces highlights on that lamp. How is that reproduced/faked with GIMP?

-thanks for your patience

edit to add: My guess is that highlights and shadows are created in GIMP by blending foreground and background and then when the texture is applied to the object, it is rotated until the shadows are in the right spaces? The other program does in fact have a texture rotation tool, but I suppose this requires advanced skill to get it right ;-)

RE: Brass texture
Update

I did a lot of reading, got confused, and eventually realized that a modification of the default "Golden Gradient" would probably work so I made a cooler (blue-er) version.

I'm now working on figuring out how to apply it to the object in Second Life (repeats rotations etc) to get it to look right. If I ever finish this I'll post a picture ;-)
