Imposters rendering issues in ver 2.20

[TanukiDigital]

I'm using grass-based tree imposters on my landscape based off ObjectMeshClutter tree objects.  The imposters are a child object of the tree object.  In 2.20 these imposters do not load, and their triangle count is set at 0.  When I toggle the Intersection option for the grass billboards the trees will then reload properly, but they do not intersect with the landscape terrain regardless of whether Intersection is toggled on or off.  This only works in the Editor, and it does not show the imposters at all(even non-intersecting) in a compiled project.  And it also does not save the imposters when the editor is restarted.

Alternatively I can use the new Octahedral imposters which create a child ObjectMeshClutter object just fine (both in editor and build), BUT these are slower to load/render (especially in the distance) and thus do not fully replace the spherical grass-based imposters that are able to be generated in the distance for large quantities of trees.

We're aware of an issue where Grass (and impostors) do not properly intersect with the LandscapeTerrain. A fix is planned for the next maintenance update, likely by the end of July.

Also, please note that the new impostors can be more demanding performance-wise. If your use case doesn't involve flying over large areas of vegetation, we recommend sticking with the old (spherical) approach for better performance.

Thanks!

That's excellent, thank you!
