No graphic is visible at all. ok, what happened (for your example files) is that while the geometry is tagged as useVAO, individual properties, in particular the vertex position properties have their useVBO flag set to false. Hence nothing is rendered. OpenSG is not very graceful right now. I'm thinking about how to make it so. > With respect to the Intel HD Graphics 4000 platform I have another > problem.

At the same time if you set the env variable OSG_NO_GL_CHECK_ON_FRAMEEXIT it will ignore the test as well. kind regards gerrit ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
