Settings for a rug (twilightrender)?

jo-ke

I've designed that rug and ordered it for my customer. Now I want to improve my skills a bit and I'm trying to reconstruct this rug.

here is the texture I've designed:

and heres the bumpmap

the render is made with the setting color/#1

is there a better setting for that case?

Make sure your bump map is a good one, simply desaturating the image is not an official bump map.

in a bump map, the white is going to bump farthest "up" from the face. black is going to bump farthest "down" into the face. 50% gray means no bump.

So if you make a good bump map, it will look 100% better.

Then it's a matter of lighting, and choosing the right material template. Lighting should be natural, or put it in a light studio. If the lighting for your test scene is too bright or too 'flat', it will not let you know how good the model/render is.

I like the design for the rug, by the way.

Thank you for your fast replay. I'm going to remodel the bumpmap...

here's another render

I've changed the contrast of the bumpmap but the result isn't as I want it to be.

could you recommend some changes?

and here's the new bumpmap

I do not think it looks bad right now...
but you see the dark lines around the edges of your flat color areas? they are making "grooves" that are not really there on the rug, and are what are making it look not real.

I would start by using the "posterize" effect in Photoshop on your original color image... this may help you to get groups of flat colors. Then use the Black and White function in Photoshop Cs3 or later that allows you to color each batch of color and how light or dark you want it to be.

The noise, I would experiment independantly with a noise map and the material template you want to use for the rug... when you think the noise is looking right, then overlay it onto the posterized black and white bump map when you get it looking right independantly of the noise.

hope this makes sense.

I only stumbled upon to your question here, and only responded here because this is the same for any render engine bump map - a "true" bump map (not just converting a color image to a contrasty black and white) makes a big difference to the look of your material.

Oh thank you.

The customer was also very satisfied. In the meantime he orderd a second one, which is in production right now.
