jimmay Posted April 3, 2017 Share Posted April 3, 2017 (edited) Hi all, I'm setting up a basic missile trails test, where the missiles are emitted by one popnet "missiles", and the trails from a second popnet "trails" I'd like a consistent amount of particles per missile as more are fired, so after some reading around I set up npoints("obj/geo1/xxxxx") in the Impulse Count for the trails popnet. However, npoints consistently evaluates to 0. I tried pointing it to a poly sphere instead of the "missiles" popnet, and it still evaluates to 0. Any suggestions? I found this on H16 build 504, updated to 557, no change. npoints.hipnc Edited April 3, 2017 by jimmay Quote Link to comment Share on other sites More sharing options...
woodenduck Posted April 3, 2017 Share Posted April 3, 2017 add a / before obj. so the path reads - npoints("/obj/geo1/sphere1") Quote Link to comment Share on other sites More sharing options...
