Cloth Room U V Stretch

  • @F_Verbaas questioned whether the U and V stretch resistance values could be set independently, and if so wold it have an effect. I replied that in tests I'd done years ago it made no difference. Well I was, not for the first time, wrong.

    I created a test using the hi res square pinned by the top most verticals. I had 5 squares. The first had stretch resistance of 0.9 the second 9 the third 90 and the fourth 900 the 5th was a control and not part of the sim

    My settings other than the U and V stretch resistance values which xould change were

    This is with U & V set the same with stripes vertical (stripes created using a u variable shader

    Here the U value is set to 10 with the V variable (0.0,0,90,900)

    Here U is variable (same range) and V 10

    I then rotated the square through 90 degrees and changed the pinned vetrts to the new top row

    U static 10 V variable

    and finally U variable V static 10

    As you can see there is certainly a difference. I will therefore make a new version of my EZCloth settings and expose the stretch settings separately. (in the Poser UI it will only show the U value)

    I look forward to seeing a the new version of EZCloth.
