Brushed aluminium material making problem

[packe777]

I'm trying to make my first vray brushed steel/aluminium material,but i'm having some problems along the way. It should be a black brushed metal mixing control keyboard,with white painted signs and markings, and with a couple of smaller emitter surfaces on it. I have made a color/diffuse map, then the black and white "specular" map, (the one that determinate what is reflective and what is not, brushed surface yes, markings- not reflective), and the one that have just emitter parts in one color (eg. white for light and the rest that is not the light emitter - black color. But the problem gets when i try to get the desired effect, where to place what exactly; i did analyze some vray procedural brushed metal materials to get the idea, but there are different settings outhere; and i just cant seam to get the right thing.

I either lose the original white markings, that turn to gray or i lose that fine brushed metal grain contrast. Does someone have experience with this kind of brushed material i'm trying to get or any hint where to link the maps(reflection filter tab?), and what IOr fresnel values to look for? Below are the pictures of parts/sections of the maps to get an idea and just a test with a gray brushed metal diffuse map and "specular" reflection filter color map, with no emitters at all.

Color:


Specular:


Emitter:


Just specular test, with strange black color for markings:

Hello there!

I made a quick test on your material problem.
Here is a image that I rendered. It has one material attached. As you can see there is an emissive layer (the screen in some foreign language :), 2 diffuse layers to control the color of the metal and give color to the buttons, bumpmap to give the brushed-feeling to places where the metal is. If you find in my render all the elements you want to achieve I can tell you how its done. Best regards Simon.

Thx for the reply, yes that is looking great, just like i need to be done. Can you elaborate more of using 2 diffuse layers, and if you can u printscreen the material edit settings tabs so i can see where what maps go to?

Re: Brushed aluminium material making problem

I think i made it. One diffuse layer is just for the brushed metal, the other one is for the markings.Then i added the markings map in black and white for the transparency of the brushed metal diffuse map layer. I added the bump, emitter parts map, and i added the color diffuse map for the reflection map, so i can get that anisotropy and blur specific settings for the brushed metal shader. Is that the way you did? See the link below that i found useful: http://software.asgvis.com/index.php...303&Itemid=480

I'll try your settings now. Thx for your reply, it was very helpful, i'll post the test render results when i do it.
