Hope no one thinks badly of me for reviving this old thread (actually the latest post was just last year so notso old)

 

I´ve read through this several times and have no problem with the gather thing, BUT as far as I can tell noone actually explained the bioluminescense effect, right?

I mean the fresnel-ish effect created by Nalif in the beginning. I don´t mean how to cast ligh onto other objects but how to get the figure to look like a jellyfish..sort of. Glowing edges and transparent/translucesnt in the middle.

 

Thanks a bunch if someone could just tell me in what end to begin doing that and I can prob learn the rest :D
