bobsanchez Posted October 24, 2011 Share Posted October 24, 2011 Hello, I am rendering some primitive spheres driven by a particle system I am trying to create a rib file with particle $AGE included in the rib. I've been trying to use the Attribute SOP to pass information out to a RIB. I am have been successful in able to write out the particle id ($ID) and particle life ($LIFE) information into a .rib file but no luck with the $AGE by reading this info http://www.sidefx.com/index.php?option=com_mailarchive&Itemid=212&view=WEB&msgid=3A96C4F3.60D9C4A5@imageworks.com&perpage=20&revdate=on Any ideas on how I can go able writing out the $AGE of a particle into a rib. Is this even possible? Thank you Quote Link to comment Share on other sites More sharing options...
ehsan parizi Posted October 24, 2011 Share Posted October 24, 2011 (edited) As far as I know, if you have life attribute, you basically have $AGE, life is a float with a size of 2. first one is $AGE and second one is your particles' expected lifespan. $LIFE is nothing but life[1]/life[2]. So, if you have a life attribute in your point attributes, you have $AGE there. Edited October 24, 2011 by ehsan parizi Quote Link to comment Share on other sites More sharing options...
