Using blending modes in Unity 4 GUI

Unity Engine
1

I know it’s not been possible in older versions of Unity, but I was wondering if Unity 4 finally has a way to draw GUI elements using blend modes other than simple alpha blending? One would think it is one of the most basic things to allow for effects in the GUI using additive or multiplication blending modes, etc. but it seems to be completely missing.

Is there a common work-around for this? I searched the manual but could not find anything. Is there, perhaps a way to blit a texture on top of the GUI elements, unrelated to the GUI class?

Thanks for any info or leads you guys may have.

No blend modes, they’re computationally expensive and most game developers have been getting by just fine without them for, well, forever.

If you want, you could implement your own GUI system that has blend modes, it’ll be slow though.

You can Blit, mostly it’s used for post processing with shaders. Look at the Graphics class. Requires Unity Pro licence.
