Grass is showing flat!

Hi there - really appreciate any help with this…
I have created my toposurface in SketchUp Pro 2025 & applied a grass material (which I had to find in 3D Warehouse as it’s no longer a standard material).
After importing into D5 Render & applying a Custom grass - it is still 2 dimensional - except for where I have stamped the surface to cut around the house & the path.
Can anyone please assist?
Images attached.
Thanks so much,
Em.


Hi @emmacain

Please try to reverse the surface (Right Click the Surface > Select Reverse Faces) in SketchUp and see if the grass shows in D5 Render.
