ok so here is my problem. in this picture i want the White outside the Blue to be Transparent, and the White inside the Blue to to White.
this is as far as i get when just using the Transparent BSDF.
As you can see, both White areas are Transparent. is there any way that i can make the Outter Area the Only Transparent one??
EDIT 1:
after using cegaton's Advice i set up the nodes and such according to the 4th example,however the full sphere seems to be transparent now, regardless of color placed on the texture.
EDIT 2:
i get the feeling this may just be too advanced for my level of skill in this current time period... perhaps somethin like this might be easier.
In this example im using a stock lightning effect i found off Google. is there any way i can have this so that the black parts are see through, while keeping the rest of the image the same?
FINAL EDIT:
turns out im an idiot and just didnt realize the Alpha channel on the Texture got removed completely some how....quick trip to Gimp and 5 minutes later i got the results i wanted
