pgreen Posted May 16, 2018 Share Posted May 16, 2018 (edited) I'm having trouble getting a clean render using camera match and Final Quality Renderworks. Rendered objects have a ring of white pixels outlining them. - OpenGL works fine - Tried multiple quality levels of anti-aliasing, blurring, etc.... and all look the same - Higher DPI reduces the effect, but it's still present Has anyone run into this? Any ideas on getting a smooth composite over a background photo? Thanks! Pg Edited May 16, 2018 by pgreen Quote Link to comment

DanJansenson Posted May 21, 2018 Share Posted May 21, 2018 (edited) If you're rendering on a sheet layer, try making the sheet layer color (or background) black. Or dark grey. The white outlines may actually be transparent areas. Edited May 21, 2018 by DanJansenson Quote Link to comment
zoomer Posted May 22, 2018 Share Posted May 22, 2018 Yes, Antialiazing tries to blur the Objects Borders against the Background. So a suitable Background, the final underlay image at best, would produce the best result. But it should also work if the AA blurs against a transparent "color". Just like a Alpha Channel for (mostly) transparent objects does. This should work for any Background. For me the image looks like either AA works against the default white VP background or the Alpha/Transparency of the AA is not considered in the final overlay. Quote Link to comment
pgreen Posted May 22, 2018 Author Share Posted May 22, 2018 @zoomer I think you're right. It looks like antialiasing is working against VW's default white background. If I change display options to "black background" the on-screen render looks great (image attached). A PDF export still shows the issue though. Thanks @DanJansenson - I tried changing layer color overrides and adding a black box behind the viewport on the sheet layer, but still running into the issue... 1 Quote Link to comment
zoomer Posted May 22, 2018 Share Posted May 22, 2018 But it looks pretty cool anyway 1 Quote Link to comment
DanJansenson Posted May 22, 2018 Share Posted May 22, 2018 (edited) As a work-around you could put a "white box" in the background, with a doughnut hole cut out in the image area to reveal the black layer background... Edited May 22, 2018 by DanJansenson Quote Link to comment
