jiahongyuan Posted July 7, 2013 Share Posted July 7, 2013 Today I compiled the POP_Circleforce( which is in HDK samples/POP/ ), but the node has no effects to particles. Later I found the problems is that the function "checkActivation" always return 0. I checked the hdk document. There is one line that says: "checkActivation() returns 1 if the POP should be active and 0 otherwise.",which does not make sense to me. Finally I removed this function from .C file and the node works well now. I am wondering if any one know what the function actually means and when we need it in POP node.

edward Posted July 8, 2013 Share Posted July 8, 2013 Which version of Houdini are you looking at? Check out the latest 12.5 version: http://www.sidefx.co...rcle_force.html I don't see a checkActivation() method on it. Quote Link to comment Share on other sites More sharing options...
