Fabric in Twilight?

Jim · 11 Jan 2010, 19:46

How do I create a decent fabric texture in Twilight? Do I need one of them there bump maps? I tried a fabric bump I found on the Internets, but haven't been able to make it look right. Maybe the cushion geometry just needs that "sat-on" look?

Cushion.skp

Thanks.

Majid uploaded a nice set of Deco Fabric materials in the Twilight Forums but only to those members with a Full Licence

Other than that you might find some in the KT forums

And what kind of fabric material would you like?

I used template > stone > rough and also a rough concrete texture in the bump slot upped to 10.000

Certainly it takes a while to antialias such rough and extreme bumps (and of course, it is nowhere from Majid's textures - or anything professional actually)

Hi Jim,

It all depends on what look you want to achieve and how close you need to render the chairs...

I'd say that you can't make it look right, because you need to apply UV-coordinates to make a bump-map look good...
I can see that the cushion is just a color (meaning no UV coordinates have been applied)...
For the cushion I would project a bitmap-texture and then in TWR I would apply a bump-map...
(Remember that you can click the "chain" in the bump-map channel in the TWR Material Editor and tick the "Invert" box...)

Like others already have mentioned, you can download a number of fabric materials from the KT Download section and use these directly in TWR...

Hope this can help you further...!?

Oh! I can't apply a bump-map to a color. There needs to be some texture (even a solid color one) as well as the bump map. Maybe I should read the manual. (Nah.)

I did find this texture on the Twilight forum. The chair itself looks about right to me. I think I can do what I want, now.

Is there a technique to "anchor" the chair on the floor? It still looks to me as if it is floating and not really on the floor. Does the carpet need depth? Maybe better lighting would help?

Thanks all, I'll check out the KT materials.

Maybe the shadows are too soft (and there is no definite shadow for the legs of the chair) therefore it looks a bit floating (I guess in SU you know how to put something onto the ground).
