Cheers Xendance, Yeah I'm using a 1bit alpha but I'm pretty sure I've got the channels set up wrong. I'm plugging the alpha of my diffuse into the opacity mask mat channel and then the blend mode is set to masked. The alpha comes out fine but it's not showing as double sided. I'm not sure if that's down to alpha sorting or…
Thanks divi, yeah an example would be much appreciated. I'm totally lost, apologies! So what nodes should I be using for reflections? Presumably I can use that along with my spec?
