hi,
I have a big terrain that where I need to plant grass.
If I don´t use edge mode, it render fast but just If I use edge mode (I needed it ON to have clean edges), the render wont start.
is this a normal behavior?
thanks

... just installed latest version 6.10 and edge-mode does not work in vray next gpu ... it works fine in vray next. for me

Hi, M55,
This feature it is not supported.
Full list of supported/unsupported renderer features can be found in our documentation (https://docs.itoosoft.com/forestpack/requirements).
I'm afraid there are several limitations to implement features like Forest Color (http://docs.itoosoft.com/display/FORESTPACK/Forest+Color) or the Edge Boundary Checking (http://docs.itoosoft.com/display/FORESTPACK/Areas#Areas-Topreventscattereditemsfrom%22leaking%22outsideanareaperimeter) mode for this render engine.
The reason is that these features work at render time, and require a custom shader for each renderer (a piece of code which runs directly in the render engine). But V-Ray RT doesn't support any third-party shaders (there is no SDK, so we cannot write code for it).
Regarding OP case,
If it is really big terrain You should try to minimize the amount of objects for ForestPack to evaluate if edge mode hiding is needed.
In both cases, I would suggest you to use the work-flow shown in the Grass Edges (http://www.itoosoft.com/tutorials/tutorial_grass_edges.php) tutorial.

hi rookas, may I send you the file so you can evaluated it?
-
Sure
Send us your simplified scene (https://forum.itoosoft.com/faq/how-to-send-a-file-to-itoo-software/)
-
i´ve just sent the email.
note that the forest in the scene doesn´t have edge activated. Once you activate it, the render takes too much time to start.
hope you can point me out in the right direction!
regards,
