      Save in a different format for the time being if you are in a rush. Or do you really need the transparent part? Use a mask preset if so.

      I dunno if it's just a native characteristic of PNGs or the way SU deals with them.

        I use PNG all the time and have never had this issue while saving from VR 1.49.01. Which version are you using?

          if your background is very bright/ white - then anti-aliasing will combine the edge pixels of your model and your background. try to make your background darker and see if it helps. otherwise, you can try turning off AA

              im using version 1.49.02

              and it does appear to reduce if i darken the background i am working on. but i see that more as a quick fix if nothing else lasting works.

              all i want is a crisp sharp image when i save my png. the transparency is important firsnt and foremost as the images i render are to be singular entities for an isometric map.

              ive added a screen shot of a png render, but ive put it onto a black background to just help show up the edges better

                looks to me like an issue with a dark material on a light background. Did you try turning off anti-aliasing (in the image sampler tab)?

                    Well, you would have to increase your resolution if AA is off, but anyhow, sounds like that may not be the issue. Is there a model or part of a model that you can post?

                      Hello,

                      in your vray bitmap material render panel, try to set the "filter type" in "bitmap buffer" on "No filter". I had good results with that setting.

                        thanks chon ill give that a try tonight. if all else fails ill post up a model..but i dont see why it would be a model. this happens even on a simple square block,
                        i was figuring it was something to do with the rendering itself more than the model

                          the idea is that with a model, we can look at your vray settings and see if there's a solution.
