Right, I've gained a bit more understanding from digging in the OSG sources:

Can you post the output from glxinfo -l.

Hi James,

So, what's the next step in understanding this? The effect claims to
use the noise texture (in unit 9, as always):
texture-unit
unit9/unit
typenoise/type
/texture-unit
Can you post the output from glxinfo -l.

It looks like the texture unit of the noise texture is beyond the limits of

Indeed. What I find strange (but probably due to lack of knowledge) is that the

Csaba, since you have the same card as me, but are not seeing this issue,
what limit are you getting for GL_MAX_TEXTURE_UNITS_ARB? (From the fglrx

I'm having the dreaded 'invalid operation after ' errors from OSG, which makes

Csaba, I have the same problem. Lock-up is caused by the Landmass shader as
soon as I switch to level 4.
Linux, fglrx
Just as a data point:
HD5770 here too, but linux fglrx. I don't see such messages, up to
quality level 3. Anything higher causes lock-up of FGFS (have to kill
it).
