Did you manage to figure out a solution to your problem?

Hi Louis,

With some more opengl experience under the hood, I think this could be a
problem:
(I have not tried it though):

This was my array definition:

;for textures
(gl:define-gl-array-format mesh-tvertex
  (gl:vertex :type :float :components (x y z))
  (gl:tex-coord :type :float :components (u v)))

I think I should keep a separate array for vertices and textures. Then
things
should work out fine. Is this correct? This is what I currently do when
using
Lispworks with its opengl ffi library.

I will try keep a separate textures array and let you know how it goes.
Thanks,
Deepak
