      Hi,

      OK, I'm here at gone 2.pm and and pulling out what little is left of my hair!
      I am trying to add people and other items to my scene.
      I have saved the PNGs and the corresponding alpha channel.
      But when I render there is always a faint (blue?) line showing at the edges of the face I have textured.
      I have checked them in Photoshop ensuring all the edges are transparent pixels.
      I have tried moving the lines inward slightly to come in tight on the image.
      Still no joy!

      I have attached an image so you can see what I am talking about.
      Hope someone can help me.

      Thanks.

      Albion Man

        It is the transparent pixels themselves that's like that. Don't have a link at hand - but there is a trick to avoid that. (sorry - I go to run don't have time to explain. should be some thread in ASGVis forum.)

          i suspect there are still black pixels left at the edges of your alpha channel. you can check it in your photo editing software.

            Hi,

            Sorry for the delay in replying I had to meet a deadline.

            I gave up in the end and used the silhouette people provided in SketchUp.
            Simply coloured them white with a 50% transparency setting.
            It worked out quite well, but I still wasted a lot of time trying to find a solution to the annoying blue fringe of pixels that showed up.
            As I said, I checked them in Photoshop ensuring all the edges are transparent pixels.

            If anyone can tell me how to solve this problem I would appreciate it.
            I have attached another picture showing a man and tree with this annoying problem.
            I have also attached another image showing the final image I was working on.

            Regards

                Hi thomthom,

                Thanks for those links.
                Nice to know there is a solution to this problem.

                I had a quick look at the ASGvis forums concerning some other topics.
                Think I will stay away from the new updated version of Vray for a while.
                Looks like they still have quite a few wrinkles to sort out.

                Are you an official beta tester?
                What do you think of the new version?

                One other thing, I am looking for a good grass material for vray.
                The type I am looking for is shown here:
                http://forum.asgvis.com/index.php?topic=4567.0

                But the link is broken.
                Do you have any idea where I can get it from?

                Sorry to pose these questions here but this forum is much more user friendly than the ASGvis one.

                Thanks.

                  Yes - I've been a beta tester since the beta first started up.
                  There are some issues - yes. I had originally planned to stay with 1.05.30 until the patch came out, but I had a model at the office that took ages to parse with the old version - and the new parsed it so quickly that I risked it. So far it's been going fine with only minor hickups. I've been working with simple clean new scenes - not any existing ones - so that has probably made be avoid many of the issues.

                  But this release is generally very good. When the patch comes out it'll be brilliant. V-Ray materials follow the Sketchup materials so we can copy between models and make components with V-Ray materials already set up. AO, render frame, IES and alpha channel support are great additions.
