Forest pack edge issue

[Luma3d]

I'm running into issues with my project. Looks like the geometry that is being hidden with FP edge option is creating some shadowing issues. See attached image. How do I fix this?

What versions of Forest Pro, V-Ray and Vantage are you using ?

Can you send us a simplified scene that shows the issue ?

Same here...
Max 23
Forest 9.1.6
Vantage 2.7.1

3ds max 2025, latest vray 7 and Vantage 2.7.1. I resolved this issue. It was because my path material was using a vray dirtmap and I did exclude the forest pack assets.

I see - it should be enough to enable "ignore invisible objects" in the VRayDirt texture, but that wouldn't work in Vantage in this case. I will log it for fixing.

Are you using VRayDirt as well ? If not, please provide an example scene showing the issue.

It's just a plane with the lawn preset from forest pack. I've manage to find a workaround. If i save the config file from vantage, close the software and live link, reopen and merge the configs, forest edge works fine. So i believe this is something with vantage.

I create a file with the problem but can't upload because of the file size(36mb), but i've upload some images showing the problem

Ya... that's happened to me too... dark area along the edge of the grass area were the edge mask is applied. Even without vraydirt.

I found an issue with the edge mode that has the same workaround, not sure it's the same issue, since I don't have the scene.
The fix will be in our next Vantage release. (Incorrect back face culling for geometry instances affected by edge trimming (until their material is changed or a config file is loaded)
