  • Large carpet - not a rug - a carpet!

    Never really sure what category to put these sorts of posts into: is it a 'General' post, or an 'Off Topic' post??? Who knows?

    Anyway...

    I still struggle with creating very realistic, luxury carpet materials in my scene. Rugs I also struggle with, but for the purpose of this thread, I'm looking for suggestions on creating a wall-to-wall carpet (in a bedroom for example). The sort of look I am going for is this:-

    Ideally, procedural would be good, as large, non-tiling bitmaps I see as being tricky to acquire, but I am open to suggestions. Would you use bump, vrayfur, displacement? Where a chair leg or a bed leg hits the carpet is another area that gives away a rendering as being unreal, but to begin with, suggestions on creating this sort of look would be appreciated. I'm guessing it has a lot to do with varying a soft reflection over the surface, which is broken up by the pile being pushed around by footprints, vacuum cleaner marks etc.

    EDIT: here's another example of the kind of luxurious, deep piled carpet I am aiming for:-

    you could try with either a strand or a small crop of strands scattered over a surface ans see if it works. rotation of the strands could be driven by a bitmap to simulate footsteps and whatnot. this way it should look good even if looked at close distance, certainly better than a 2d texture.
    I think bertrand benoit has some rug strands already modelled that he shares on his blog..

    edit:
    yep, there you go:

      I will take a look. This is as far as I got in about an hour or so. What do you reckon?

        looks good to me. how are you going about it, is it displaced?
        did a quick test with the scattered geometry approach, I reckon one can get decent results, even though it may be not that practical in your scene. and I'd say your carpet is already coming along nicely.
        here's what I got so far in case you're interested:

          The color variation pattern looks great - it's a bit flat but if this were for stills i'd just overlay a photo into that in PS and call it done.

            Its quite complex actually - it started off being quite simple but then there were several noise/falloffs/blends etc. I also have a little bit of displacement in there. Its a 3.5MB zip file if anyone wants it. If you can improve on it, let me know...

            (If I had the skills to be able to paint a matte where all furniture legs touch the carpet (within the viewport) I guess that could somehow drive the depth of the displacement, making it look depressed slightly. Not sure how to do that though.)

              Interesting result. Looks a bit more like a bath mat though (no offence)

                ahah, none taken. you're right, the strand I scattered was modelled for making towels, I guess it can't just work for rugs or carpets..

                  I've uploaded the zip file in my post above. Have a go with it and see if it works. I'd be interested to know how scene specific it is. One area that was annoying me was a sharp looking edge in the wider shot. Not really sure where that is coming from.
                  Kind Regards,

                    can you not use a VrayDistanceTex map to drive the displacement for the furniture? (you can add the relevant objects that you want to depress the carpet)

                      Sounds interesting. I've never used VrayDistanceTex before...
