Hi,

I am trying to change the repeat rate of textures on an object on the fly.
Right now, I set two pfVec2*, (texcordsfat, texcordsthin) and then try to
change the associated objects PFGS_TEXCOORD2 geoset attribute:

   for (i = 0; i < NUM_BLOCKS; i++) {

      if (hapticsVS->cylinderTex[i] == TEX_THIN) {
         pfGSetAttr(phantomVS->objPtrs[i].gSetPtr, PFGS_TEXCOORD2,
               PFGS_PER_VERTEX, texcordsthin, NULL);
      } else {
         pfGSetAttr(phantomVS->objPtrs[i].gSetPtr, PFGS_TEXCOORD2,
               PFGS_PER_VERTEX, texcordsfat, NULL);
      }
   }

This doesn't work, but I'm not sure why. Is there a way to do this? These
blocks change from thick to thin patterns periodically, but right now they
just stay how they were initially set. I have verified that these
statements are being reached, and the pfVec2 arrays are malloced from the
shared arena.

Thanks,
Keith
