Panel Reference

Density / Viewport Density — total amount, and the fraction shown in the viewport (renders always use 100%).

Reference Camera — camera used by Align Rotation & Distance LOD (empty = active camera).

Distance LOD — density fades with camera distance (Start / End / Min).

Card Width & Height / Scale / Variation / Seed — blade dimensions and randomness.

Trim Cards — cuts card geometry to your silhouettes; faster dense close-ups.

Align Rotation — all cards face the camera (billboard style) with slight jitter.

Patch Scale — noise-driven regions of uniformly tall/short grass, or plain random.

Ink Outline — pre-baked outlines (zero render cost): thickness, opacity, color.

Base / Clump Shade — painted-style shadow masses and darker blade bases.

Cloud Shadows — large soft shadows drifting along the wind direction.

Geometry Blades — real ribbon meshes instead of alpha cards.
