Strange Problem with vertex arrays
Author
I am getting lost...
can you tell me the difference between this two codes? One is with vertex array and the other is without vertex array.

The shader has this parameters:
fragment shader:
PARAM light0color = state.light[0].diffuse;
PARAM ambient = state.lightmodel.ambient;
PARAM light0atten = state.light[0].attenuation;
vertex shader:
PARAM mvi[4] = {state.matrix.modelview.inverse};
PARAM mvit[4] = {state.matrix.modelview.invtrans};
PARAM mvp[4] = {state.matrix.mvp};
ATTRIB tangent = vertex.texcoord[1];
ATTRIB binormal = vertex.texcoord[2];
ATTRIB normal = vertex.normal;
thsi is the code with the parameters only. not all the code.
The problem i have is at lighting. using vertex arrays is not correct.
any idea what is wrong?
thanks in advance!
a few things...
quick note, your drawing 35 indices in the immediate mode one
and 34 in the vertex arrays one, but they are triangles, in both cases, your last triangle will be incomplete...

yes man. you are right. I didnt knew that i must enable 'GL_TEXTURE_COORD_ARRAY' for all the texture units i want. thank you
no prob, did you also take note of the vertex element count being invalid?
