Forest Pack Grass Preset

[PX2937]

Hey, I work on a lot of large scale estate scenes using the preset for large areas of grass, for example if an area of grass ends at edging to a path way, there are always areas in which there are gaps, where the scatter clips that object as it crosses the include area/surface, are there any tips or tricks to gain a cleaner look straight out of render? Currently stamp every gap in post but cant be quite time consuming on complex areas. Maybe increasing the density could fix this? But could make the scene a lot heavier. Thanks!

Hi, I'd say it is typical for low density. You can decrease the threshold or change the density to a lower size. I assume you are using the edge mode to prevent overlaps. Anyway, all of these things in large real estate projects makes my scenes slow for a work. So I am not using the edge mode or don't push the density much, but I solve overlaps or gaps by second FP that has the same area as the first one, but it has much smaller proxies and use Fallof Affect (AREAS) parameter to scatter these small proxies only along edges.
It is sometimes better also do fallof affect parameter on first FP to cut proxies out of edges.

So in final, you have one FP for inside parts of areas and second one only for edges. This way my scenes still go fast for render and fast for work.

Hey thanks for the reply, that's a good idea that! I'm going to give this a go on my next build, thank you

To use smaller items for edges, as Thomas mentioned, there are several possible setup options - for example, you can also use the bundled effect 'Change items by distance to boundary'. If any gaps appear, you can quickly fix them by adjusting the Distribution Map settings, specifically the Density or Offset X/Y values. This should resolve the issue, as shown in the attached screenshots.

I hope that helps.
