     You do have control over the bind for each of those attributes and can
     use the PFGS_OFF token (pfGSetAttr) for geoset color. I guess you
     would need to watch out for the texture environment for that geometry
     as well ( only DECAL )
      
Hi all,

 Does anybody know if it's possible ( I guess it's not ) to use vertex arrays
in
2.1 that only pack normals, texvertices and vertices, without the per vertex
color field ?

 In case not, is it worth in IR to put the colors even though you're not going
to use them and pack it all, or send separate arrays for normals, texverts and
coords ?

 Most of the objects we use have normals, texverts and coords but colors are
used in only around 10% of the objects, so that seems a waste of host to gfx
bandwith ...

 Thank you for the help,
