Ha, further evidence that the world is truly flat
Correct me if I'm wrong, but having a look at SpeedTree info it seems that the issue is really how the plant object is made available for use in Lumion. The SpeedTree plants can be angled to fit specifically to sloping terrain (not sure though about grasses), but that's only at the create(and compile) stage.
So Lumion provides a finalised plant, that for simplicity has no pitch or bank in order to fit the majority of scene requirements. In order for users to have plants sloped, it would need specific plants made with some slope(maybe pitch only) value options such as 10 degrees, 20 degrees as additional plants for the library. These could then 'fit' most slope scenes but not all situations.
Further, it would generally apply only to types where the base size of the plant is wide such as some of the grass block types where you notice it not conforming to the slope. Trees and single grass and plants can generally be positioned to look OK on any slope, apart from ones specifically requiring change in growth angles (topic covered elsewhere earlier in year).
Most of the scene samples from the SpeedTree site are reasonably flat, even the golf game, but there are a few pics that indicate sloping plants for grasses eg here
If the scene required it and closeup camera work revealed the grasses, then I guess it could be worked around by just using single, non-area sized grasses, so long as the number of objects didn't affect framerates/rendering speed too much.
