I am using Forest 3 on a pretty heavy scene, which I have populated with 2 different types splines.
The first, for closed splines, I use the 'Include Area' which works just fine
For the second type I use open splines, and select the 'Following Path' option . I find that when I close the max file and reopen, the forest tends to disappear, and will only reappear when I usually pick the spline again.
This is rather annoying, as I will sometimes render a scene, only to find out the spline path forest has not appeared on screen (or in renders)
Has anybody else had this problem? Is it a known bug?
