When I try to add a grass texture or anything else using the paint foliage button(paint details) nothing gets applied to the scene window. The blue marker appears but when I click it just doesn’t work. I’ve also zoomed in quite a bit to make sure I wasn’t too far away to see and still nothing. I don’t know if its my computer or not, the graphics card is up to date. Any support would be appreciated.
Gorath,
Once I framed the terrain I was able to see the grass, and after that I could see all the grass patches I was attempting to make before
How exactly did you manage to make your grass visible? 
I do not understand this issue and have altered the detail distance etc. but still no clue how to make my grass visible.
maybe because you have more than 2 audio listeners. you need there only 1
Hey guys thanks for the responses. Once I framed the terrain I was able to see the grass, and after that I could see all the grass patches I was attempting to make before.
