Question by MXMRD · Aug 18, 2014 at 09:53 PM · 2d sprite transparency

Can I change the transparency of a Sprite only in the area where it is overlapped by another one?

Hey there,

I am looking for a special graphical effect concerning sprites. It should occur when one sprite overlaps another. Can I make only the overlapped area transparent, but not the rest of the sprite?

I have searched google, the docs and the Forums for solutions but wasn't able to find any that fit this particular problem.

If this should not be possible with sprites, can I achieve it with any particular mesh renderer/shader?

Thank you in advance! (and sorry if noob question, but noob)

You'll probably need to write your own shader to do this.

I'm no expert on shaders, but I'd imagine you'd want a transparent shader that checks if anything is already rendered, and outputs a transparent pixel. If nothing is rendered it outputs a opaque pixel.
