Hello,
I'm having an issue with coloured glass. When I save the image with the alpha channel enabled, the glass has no colour. When I save it with alpha chanel disabled, the colour is there. The problem is that I don't want the HDRI included as I want to place a background image separately in Photoshop.
I've added some crops to explain what I mean. As you can see, the image with alpha channel diabled shows the blue glass as it should be but the one with alpha channel enabled shows it without any colour.
I'm using absorbtion medium to get the colour but I've tried it with transmission and it has the same result. I'm using the Pathtracing kernel and I have fake shadows enabled. Switching off fake shadows has no effect. I've also tried a separate HDRI for the background set to Visibility Environment but with no success.
Does anybody have any suggestions?
Thanks,
Rico
