A Bubble

[NeoN]

I'm interesting in doing something like a bubble. The problem is that I don´t Know how to do a good transparence effect.

If someone knows any form to do this?

I've tried with blending, but the results haven't been very good.

thanks

One way is to modulate the opacity with the magnitude of the specular component...
