[osg-users] pragmatic shaders changes?

[OpenSceneGraph Users]

Hi Nick,

#Pragmatic shader composition should be working mostly the same in master
and the 3.6 branch.  I haven't seen reports of issues.

In what way doesn't you application work?  What happens if you remove the
() around your #ifdef i.e. use

#ifdef MY_DEFINE
...
#endif

The OSG itself won't have any influence over this particular behavior, it
just injects the #define so if the above tweak makes a difference then
it'll be down to GLSL compiler in the driver changing it's behavior over
time.

For debugging shaders it can be useful to enable the OSG's debug
notification output.  This will include output of the shaders to the
console that you can redirect to a file and then review what GLSL code the
OSG is sending to the driver.

Robert.
