I've used maya Arnold a lot and created glass/plastic materials before. So I know this is a weird one.
Usually I just forget to turn up my Transmission Rays which is why I get black. But not this time.
When I turn the Weight up to 1 I get basically solid black. But when I turn it to around .9 I kind of get transparent . And 0 is just it's base solid colour which is white.
What's going on here?
Everything's got Opaque turned off.
