[osg-users] Trouble with a simple shader program.

[Alexander Wieser]

Hi,

unfortunately there is no negative output, the shader compiles fine.

I doubt there will be any errors if the input channels are simply not set.
In that case they will be zero and the output vertex will also be zero, which would explain the lack of any visible pixels, can't be sure though.

Thank you!

Cheers,
Alexander
