jit.gl.slab difficulty with "pool 3-d nurbs" example

    Jan 13 2013 | 6:59 am
    i nested the "pool 3-d nurbs" example in a node, so as to use some shaders - but it seems that shaders will not work for this patch and i'm not entirely sure why... i included a little "switch" object in the subpatch to compare the difference in output... can anyone help?
