Hi,
  I expect the following code fragment to produce a model that has 10 billboard particles in a line. My "particle.flt" files is just one billboard particle. When I load up the new model, "line.pfb", into perfly or any other Performer app I see the model correctly for one frame. Then all the particles relocate to the position of the one particle that is furthest from the camera. But if it draws correctly on the first frame, I would think it could draw correctly every frame. Anybody know why this happens? I'm using Performer 2.2.

Terry

        pfGroup* pgroup = new pfGroup;
        pfNode* particle = pfdLoadFile("particle.flt");
        pfDCS** blobs = new pfDCS*[10];
        int numblobs = 0;
        for(i=0; i<10; i++){
                blobs[numblobs] = new pfDCS;
                blobs[numblobs]->addChild(particle);
                blobs[numblobs]->setTrans(i * 1000, 0, 0);
                pgroup->addChild(blobs[numblobs]);
                numblobs ++;
        }

        pfdStoreFile(pgroup, "line.pfb");
