Heya Folks,
I'm doing some forest stuff at the minute and I've had the odd problem with it. One really obvious one is if you set "visible to camera" off (I was using it to render a contact shadow pass for example) then you'll get a load of glitches in your RGB and the shape of some geometry knocked out in your alpha. This render has a vray dirt used for the red and green pixels driven by some forest systems and you can see some corruption in there.
The alpha shows a load of unwanted things too:
And here's a simple scene with vray 3.2.03 and forest 4.41 that gives you some unwanted geo causing artifacts.
forest_4_41_alpha_error_max_2014.zip
I've found that it's pretty difficult to use a forest system in a vray distance text too - it's as if the distance tex breaks forest's ability to lazy load and so you'll end up going over your polygon limit and the forest object won't calculate or render.
Cheers!
