flakie Posted May 14, 2018 Share Posted May 14, 2018 I was working on a rendering with a lots of glass , but when I compose the image the backround has the Alfa Chanel but the glass is opaque. Is there something I need to turn on or adjust in the Vray material? Thanks Quote Link to comment Share on other sites More sharing options...
Andrew West Posted May 14, 2018 Share Posted May 14, 2018 Increase the maximum number of recursive rays. V-ray settings- Raytrace- Max Trace Depth- set it to 7 or more. This will slow your render but affect the alpha as you need. Justin Montoya 1 Quote Link to comment Share on other sites More sharing options...

Spannerhead Posted June 28, 2019 Share Posted June 28, 2019 Having this issue in RenderZone. Both Glass, Accurate and Glass, Simple are opaque when rendered with an alpha channel BG. Any way to make them transparent? Thank you! Quote Link to comment Share on other sites More sharing options...
