VRay 5 PNG Does Not Save Transparent Through Glass

[robert_crockett]

Hello everyone,

I have been unable to save a PNG with transparent background through glass. Rendering outside renders a transparent environment. Interior renderings do not allow the background to be omitted. Please help!!

It may be an issue with the background being transmitted through the glass. I have unchecked the environment options for Shadows, Affect Diffuse, Affect Specular, and still the environment is shown when saved as a PNG. I also tried different environment types and pasting my model into a fresh unedited project file.

Let me know if I am missing a setting please. Thanks!!

If I understood correctly, you most likely need to set the refractive material to affect all channels (or color and alpha).
