Why is the attribute aliasing enabled in the first place?
If I am not wrong I have to enable attribute aliasing to use osg_Normals from
shaders.
You can use gl_Normals if you use a compatibility profile and no vertex
attribute aliasing. You need this only for pure OpenGL 3.0 and beyond.
Try to render it with default profile and use a version 120 shader to
check with gl_Normals etc. If this works out, you are setting up your
geometry correctly.
Use debugging and minimal examples to get to the problem and check the
examples (in terms of creating geometry, using Core profile and shaders)
Have you tried loading a osg model and display it with your shader?
The cow in ScreenShot168.png is rendered with my shader (It is a simple shader
just for show normals)
Looks okay. Still the osg_Normal might default to attribute slot 0, so it
I still don't get what you are trying to achieve.
I want to draw some walls with textures and a model with shaders.
Should I render walls with a shader too?
