How to blend 2 quads in the same location

Hi all,

I know this has probably been answered before so please point me to the right post if so.

I need to blend 2 quads together. One should fade in on top of the other when I call a script function.

The quads are instantiated in a script. I was thinking that one quad could be completely transparent, and then fade in after the function call.

Is that the way to go or is there a better way?

Could you describe more what are you trying to achieve, what is your final result?

Normally having two surfaces overlap is a very bad idea (Z-fighting artifacts).

Instead I would recommend using only one plane, but a specially written shader that will blend the two textures you need in a crossfade manner. I can write such a shader for you if you describe what sort of textures you’re blending (what effect are you trying to get).
