Hello. Did you lay out these plants with the brush tool? Currently D5 has a distance limitation for the reflection of brushed plants, they won’t be reflected if they are more than 900m away from the reflective surface. You can check the distance.
If this is the problem, it is recommended to just place the separate plant models or use a backdrop plane.

I used the path tools for the trees, is it affected too?
