Hello! I want to use immediate mode for drawing some object. I use the following code to apply vertex attributes (for GLSL shaders):


glBegin(GL_TRIANGLES);
glMultiTexCoord2fv(...);
glNormal3fv(...);
uniform = glGetAttribLocationARB(m_pShader->GetProgram(), "tangent");
glVertexAttrib3fvARB(uniform,(GLfloat*)...);
glVertex3fv(...)
...
glEnd();

The problem is, that when I use this code, that triangles are not displayed. When I comment out the "glVertexAttrib3fvARB"-statement, the triangles are drawn. Drawing the triangles with vertex arrays and VBOS with "glVertexAttribPointerARB" works perfectly. Where could the problem be? thank you,
