Hi Renato,
By default, many shadow technique use the Texture Unit 1.
And as I can see, your model use this one too.
You can check your model or change the texture unit use by the shadow.
If I'm right, this will fix the probleme

Could it be that you are hitting up against the NVidia driver issue
relating to the handing of uniform arrarys. The svn/trunk version of

this.

I will like to check has anybody successfully run OSG on such a
configuration. On Blade servers, typically the default display adapter is a 2D
graphic card. The additional GPU does not show up as the default adapter and
thus OpenGL is unable to use it.
The error that I get is
Hi,
Oh, I thought the tesla cards are only usable for GPGPU and not for graphic
usage... Am I wrong?
So you can use CUDA or OpenCL. For example in OSG for VPB with CUDA enabled
NVTT..

Hi Ga,
The OSG supports VBO's within the osg::Geometry class so could do what
you need in very straight forward - far easier than with raw OpenGL.
Just do geometry-setUseVertexBufferObjects(true); See osggeometry
for more details on osg::Geometry.

I have a performance regression with 3.0.1. My application works fine

This seems to be linked to specific positions/orientations of the

A colleague of mine has found a fix for this issue. I think that the question

I'm implementing shaders in GLSL 140+ (i.e. no built-in uniforms), and I've had

been inherited (or directly applied).
