[osg-users] porting old code to the latest osg issues

[Trajce Nikolov NICK]

Robert,

are there any changes in the shader management, I mean are the shaders
changed by the OSG code somehow (I am using the built-om uniforms)? Here is
my shader source line:

"varying vec4 projShadow;\n"

that apitrace logs as (this is being compiled but differs from the original
shader source):

out vec4 projShadow;

and then I get this warning

warning C5060: out can't be used with non-varying projShadow

?

Thanks a lot as always!

Nick

p.s. Chris, thanks for the apitrace hint
