U5.5.0f3 and SpeedTree bugs

Hello. I used SpeedTree trees in my project and i have some problems

I set speedtree to TerrainEngine and it works fine:



Then I put the Terrain to the prefab and exported prefab to bundle. This bundle is loaded into another project and instaniate to scene. And I see problem with pines (bought on AssetStore ).




At the same time, birch and shrubs (also SpeedTree) look good. How to fix this error with pines?

And another problem: sometimes distant billboards flashing black and I do not know how to fix it

 

Is there anything you need to regenerate when you import into the other project? I'm not a SpeedTree expert, but as an example, when you import Gaia you have to go select the included SpeedTree instances and click a re-generate button, although that shows in the editor as an error, not a drawing artifact during render.

 

ty. reimport and regeneration pine materials helped.
but i have another problem with the flashing trees

 

No idea. Watching on my phone it almost looks like a fighting. Maybe something wonky with the lod levels?
