Silk Material? (UDK)

MikeFriel

Hello All,

So I'm creating a collection of fabric materials such as cotton, velvet, leather, silk, wool... Thus far its going ok with the basic fabrics pretty much down. However I seem to be struggling with creating a silk material, and tbh not sure where to start with this type either :S

I've searched the net hoping to find some tutorials or examples of what people have already done with no luck Does anyone know how to go about this?

Help would be much appreciated

Thanks
Mike

Silk looks a bit metallic to me. It depends on the weave but the shiny silk almost looks like metal.

Silk is easy it's all in the textures. Just give it a dark red diffuse and a bright red specular ( assuming the silk is red). Give it an upper mid range gloss value and make sure the normals are convincing.

Hmmm, oke i'll give this a try. Appreciate you're suggestions

Silks are nicely represented by a Minnaert shading model as the material has a lot of retroreflection to it.

But yes you'll want a deeper color of whatever color your silk is for the diffuse, and the same or more saturated color for the specular.

Good thing about Minnaert is you can use it with regular Phong lighting as well

Awesome! Thanks for the help guys the Minnaert shading model is exactly what I was looking for, you can pretty much go from Phong > Silk > Velvet... very nice
