Foliage (hair particles) disappearing after applying

[teddysalad]

Hi, I’m a beginner trying to make a simple forest scene, but I’m having trouble with hair particle system. I’m using this for the leaves of trees. I have an issue when applying the leaf particle system modifier, the leaves disappear. You can see the images below (please excuse the crappy models ).

I’m not sure where I’m going wrong with this, but I’m new to particle systems and reached a dead end. Would anyone have an idea of what I’m doing wrong? Thanks!!

It has to do with using multiple Particle systems, I believe…
If you take the Leafed out Tree…and make the instances real…then Join all the instanced leaves you get a leafed tree that will display correctly…
