I'm trying to develop a rendering that will be used on a website and I need it to be a transparent PNG file. The object i'm rendering is a sheet of glass using the "glass" appearance type, with a transparent grayscale gradient overlayed on front. My glass has a sightly blue tint to it in the glass appearance.
When I setup my scene using a white plate to ensure all the colors are correct, and then I got to save as a PNG with alpha channel, my blue tint doesn't render out. The gradient shows just fine though. Of course I have to add a white backdrop to see anything.
I'm scratching my head on this one. Thoughts?
Preview in Visualize with a white plate. There is a transparent gradient decal on the glass:
This is what I see rendered with the white plate. There is a slight gradient. This is correct:
This the rendered PNG with a white background added in post processing. Notice the blue tint is gone but the gradient remains:
