how i can make a pulsar?
Y'know, that's a good question, I don't know how you would create it naturally. I actually was browsing all the sims in the menu and I came across the simulation "pulsar." I opened it and started experimenting. Next, I just saved the pulsar so I can load it in any simulation I want, then you can mess with individual parameters.
If you want to open the simulation without having to search through all the thumbnails, just type "pulsar" in the search bar under "open," then it should be listed.
EDIT: As is turns out, saving the pulsar and loading it later doesn't work.
