sethpomerantz Posted June 19, 2007 Share Posted June 19, 2007 Hi, I'm working on a particle sim, wherein i need to have instanced geometry creep along a surface and be oriented to the normal of the surface. I have tried using an upVector node in the POP and assigning it the value of the surface normal e.g normal("/obj/geo2/point1",0,$POSUVU,$POSUVV,0) . this however doesn't appear to work. Any suggestions or examples as to how to get this to work? -thanks Seth Quote Link to comment Share on other sites More sharing options...
MIguel P Posted June 20, 2007 Share Posted June 20, 2007 Just add an Attribute Transfer POP and transfer your normals from the geometry. You can increase the samples to smooth the transfer. Quote Link to comment Share on other sites More sharing options...
Visual Cortex Lab Posted June 21, 2007 Share Posted June 21, 2007 look for the "orient" attribute on your particles points... they often get your copied object a bad orientation... if you have orient attribute.. try removing it. Quote Link to comment Share on other sites More sharing options...
