Grass terrain

Grass joins the simulator's terrains. The pictures show it rendered as blades 3–9 cm tall; in training it slows the lower legs below the grass height, over mildly uneven ground, with height and resistance rising by difficulty level.

• Rendering only: about 160,000 blades on soil, with sun, shadows and fog; the legs pass through the blades
• Training model: resistance on the lower legs below the grass height, as one terrain type of the multi-terrain field
• First run, being set up: the multi-terrain walk trained further on a field with grass, against the same steps without it
