lzoper Posted June 11, 2012 Share Posted June 11, 2012 Hi. I saw this topic and tried to figure out how it works Creating simple tornado motion using pointcloud And I had a few questions: 1. In vopsop1 he create a parameter edge_dir and create a new attribute. How Houdini understood what he had in mind. 2. In voppop1 why he use two global variables and two point cloud open. 3. In voppop1 why he use rampparam if it's not connected to outputs. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
bloomendale Posted June 11, 2012 Share Posted June 11, 2012 (edited) 1) Edge_dir and edgef attributes were created by Point SOP right before vopsop1. 2) it is not necessary, maybe forgot to delete. You can use only one pcoopen and globs. 3) see 2) Edited June 11, 2012 by bloomendale 1 Quote Link to comment Share on other sites More sharing options...
lzoper Posted June 11, 2012 Author Share Posted June 11, 2012 Thank you. Removed all unnecessary, it became clearer. Maybe you say the best way to learn VEX, not just read the help. Quote Link to comment Share on other sites More sharing options...
