Title: ColorMask in shaders
Post by: ryan on August 09, 2012, 05:41:51 PM

I'm playing around with a RenderTexture and NGUI for some full-screen post processing and noticed that all of the shaders are setting ColorMask to RGB.  (Inconvenient for me, because I want alpha values written out when rendering to a texture.)  Is there any specific reason for this, other than that alpha isn't really needed when rendering to the screen?  It looks like everything still works fine if I change it to RGBA, but I haven't tested thoroughly.  Am I better off using a replacement shader when rendering to a texture?

There is no particular reason for this. You can change it to RGBA if you like, or get rid of that line altogether.
