  • Shadow Pass problems

    Hi,

    as You can see, the normal Rendering works fine with the shadows.
    Everything looks perfect. One big shadow in front of the hero.

    There are 4 simple rectangle lights from all 4 sides - nothing special!

    But when You take a look onto the shadow render element, there are bright gabs inside the shadow,
    which is wrong and results into wrong composeting.

    It only happens with more than one RectLight.

    Any idea what happens here.
    Hopefully You can help me.

    Thanks so much,
    Jörg

    I´m using Maya 2012 and vray 2.25 nightly 23014 from May 17.
    But perhaps the version is not the problem!?

        thanks man,

        I need a pass whith the shadow like in the normal rendering.
        So I can add the shadow in Post on the real footage.
        Without the strange holes in it.

        cheers,

          Then use wrapper material and ull get alpha with proper shadow. Tbh I don't remember using shadow pass from a long time.

            Like DADAL said - with the help of VrayWrapper material you could catch the shadows and place them over a real footage.
            Here is one very simple tutorial about it:

              Thanks for all reply,

              but I´m using the wrapper - and for test a normal shadow-RE!
              In both cases, I´ve the same probs.

              The shadow in normal rendering looks perfect - the RE-shadow or/and the wrapper shadow result looks bad!

              When I switch off 3 off the four rect-lights, the shadow is perfect in RE and wrapper.
              When I switch on a second or third, etc. rect-light - the shadow becomes bad.

              Perhaps I,ve to extract a sample scene which shows my probe here.

              Never seen before that strange thing?

              Thanks guys,

                Yes please - it would be better if you send us a scene.

                  Umh yea send over the scene. If you using wrapper you don't need render element. You only need alpha from render. It depends how you set it up at the end.
