Does anyone know of a work around to implement an edge mode with Chaos Scatter - I think Corona has an option for this but Vray doesn’t.
How does this edge mode work? What is the goal? Forest Pack has tons of options, but is of course not free.
If it’s for grass, then the trick I used with Forest, before edge mode was completely supported for Vray, was to use clumps for the main scatter
but leave a gap as they approached the boundary and fill that in with either smaller clumps or if necessary individual blades.
Apparently Vray clipper will work too, so you could try both.
Oh, the way you thin grass next to the edge? I have done that a few ways, like clumps for a larger areas and then smaller areas next to the edge use individual blades instead. Sometimes using different scaling or vertical offsetting can help for that look too. Forest of course does most of this, but the Chaos Scatter does not yet.

You will see Edge Trimming very soon. Look out for an update notification in the upcoming weeks 
woa that’d be great! will it work for GPU rendering?
Yes, I expect some minor problems at the beginning, but we’ll clear them out.
Edge trimming is now available with the latest hotfix.
I couldn’t reproduce that on my end so the edge mode issue might occur when there’s something more specific in the scene. Would it be possible to send over a scene sample to philip.shounev@chaos.com so we can troubleshoot ?
