[osg-users] Setting alpha channel in Frag Shader does not work.

Guy, Good Catch. Unfortunately that is just a typo in the post. My actual shader only writes out 4 values.

I do need to pass values along the alpha channel outside of 0-1. But even if I restrict myself to values from 0-1 I still get the incorrect data passed down to the image.

Any other ideas?
