View Full Version : need help texturing

01-16-2012, 09:42 AM

I've got a cylindrical object that needs a brushed brass texture. It's modeled based on a real object so I need to match it pretty closely.

My first thought was to photograph the object and use the image map, but being cylindrical I get all kinds of spec and reflections, making it very difficult.

Any ideas how to texture such a thing?

A bit of both forum and general google searching will find u far more info than anyone here's gonna be able to give.

The basics for making good metals will mean looking up how to do a fresnel effect for reflection/spec and diffuse... done with gradients in LW. You'll also find that you need an environment to reflect, default black backdrop aint no good.

Getting into the details of the brushed effect, you'll want to look up anisotropics for ref or spec, in LW this is easiest in node editor with shader nodes.

And also worth looking up is gonna be the conductor node in LW, which is a great one stop shop for metals, including roughened/soft reflection ones, though not necessarily so great for aniso ones.

This is a great vid made by Newtek's very own Matt Gorner, before he worked for them... useful video though. It's on this page...

Thanks for the replies!

I really get what you're saying about the metals and environments and will definitely continue looking around for tips.

The object I have isn't very reflective so I'm not sure a good reflection map will help in this case. For reference, check this:

example (http://lh6.googleusercontent.com/public/bTwLmx4JZxR0IWQomraqqL8TYKwliwbmSP6J8jyd5DWfk9Eo7Z iTOHDWNOor-Q-gpxPKgg4jGHL5UEV1KexHXFIx50aI-qbbdOQEpjc7dXIT4Q4n5C7PZKlDhL5l_Pz5s3PWF-mHyiWwIhERj3c3nkxPTRxqb4vrs4SNBG5mJ0kJNubkp_Cn1yc_ UogV8T7Jj9jQzGfbX6i7JGPs5kbmrG1yZTP3aJv9vstuGNjfgx x-vJk0UKv0g3pbPspUHmy4YFNvapcCQUg9pjUBRsvPWzLiqr-ABMiqv6q8G1j8hf4kjUK_cxIRdgISP3ghUHTpwLCF)

My surface is very similar to this but without such pronounced brush marks.

You could also check out Kuzey's metal pack. Saved me a lot of time and effort. Also, you can break them down, see how he created them and maybe get something a little closer to what you want:
