Other kinds of cloth...

I am starting to try and do some experiments with Iray now that 4.8 is out. I worked long and hard in 3DL to get a cape with a stars-and-stripes pattern on (Supercape) to look "clothy". I've fiddled with the same normal/bump map in Iray but I have not been able to get it to look right. I thought it might just be easier to use some presets rather than trying to do this by hand. But in the Iray presets folder that comes with 4.8, the only "fabric" type shader presets available are velvet or satin. Neither of these is correct. I want something more akin to cotton or perhaps even denim.

Does anyone know if there are presets I can get for Iray that will provide that kind of texture? It is very hard to tell from various product pages which ones might do that AND be compatible with Iray.

Thanks!

There is this one at least : http://www.daz3d.com/super-shaders-armor-fabric

It says on the Product Page :

Please note that while this product uses the DAZ Studio Default Shader System it does render very well under the NVidia IRay Render Engine with some minor tweaking!

It may serve your purpose.

I dunno what "minor tweaking" the author is talking about. I have had tons of trouble getting Super Shaders to work with Iray. It definitely did NOT work to take a fabric-textured item and convert to Iray shaders. It went from looking like fabric to looking like shiny latex. I tried modifying some settings but I have no idea what settings to change. I suppose I am tweaking the wrong thing.

What DID work was using my original bump map as a bump but NOT a normal, and tiling it x3. That at least is looking "cottony" to me. Free DLs from the web FTW.

You could try sending a PM to the vendor to ask what tweaking he did to get them to work correctly?

It may be something simple.

Greetings,
90% of the surfaces I have to convert have the 'Plastic' lighting model, and come across WAY too reflective. E.g. the wallpaper in the Book Nook was reflecting the light next to it like it was a mirrored surface. When I chose 'Matte' for the lighting model, the Iray auto-convert came across much nicer.

So that's the first thing I look for, nowadays...

I just successfully managed to use my own texture with bump and a diffuse map.

Here's how I did it.

I applied the mahogany floorboards shader to a sphere.

Then I went into Shader Mixer and imported the material from scene. To do this you need to have the object and the surface selected.

On the users parameter block change the image to what you want to use. I did this on diffuse, bump and reflect.

Change the tiling parameters to suit your needs.

Hit apply and render.

At this stage still working on settings myself...so really can't help more than that
