Grass bends around you and your friends, making a shared space to sit, lie down and spend time together. INTERACTION • Nearby players share a clearing. When friends gather, their bending areas merge and follow the group. • Lying down flattens the grass further and stretches the area along the body's direction. • Grass rises again after players leave. Soft edges, height-based fading and gradual transitions blend the interaction into the field. • Up to four active groups per client, with the local player's group first. GRASS APPEARANCE • Adjust wind direction, speed, strength, frequency and turbulence. • Set blade-tip and root colours, local colour variation, root darkening and night dimming. • Responds to scene lighting and fog. Grass height, width and density can be adjusted independently of the field size. WORLD BUILDING AND CONTROLS • Adaptive Field: set the width and length of a flat rectangular grass area. The included prefab starts at 16×16 metres. • Repeated 16-metre grass tiles and four mesh-detail levels keep the layout adjustable. Distant grass becomes sparser rather than disappearing at a fixed cutoff. • Preview changed dimensions with the included editor menu, then save. Width and length also update automatically during play. • Adjust edge softness, near/far detail transition and distant density. Move the root or rotate it around Y to place the field. • An optional visual ground can be hidden when your world supplies its own. The Adaptive prefab has no collider: use your world's walkable floor. • Create independent fields with the included editor command, which duplicates their materials and updates the required bindings. • The original Terrain workflow remains included, with independent-instance preparation and terrain transform tools. Existing Terrain worlds are not automatically converted. • Configure interaction radius, flattening, group-merging distance, smoothing and update interval. Other Udon behaviours can call SuspendInteraction / ResumeInteraction. INCLUDED • Grass shader and UdonSharp interaction / Adaptive Field components • Grass meshes, blade textures and green ground texture • 16×16 metre Adaptive prefab and sample, plus the original Terrain SmallField sample • Editor authoring tools, a square cover and optional original-world post-processing settings • Full features, installation, update instructions and usage terms in English, 简体中文, 日本語, 한국어 and 繁體中文 REQUIREMENTS AND SETUP For Windows PC VRChat worlds using Unity 2022.3.22f1 and the Built-in Render Pipeline. Install Worlds SDK and UdonSharp through VCC before importing the complete unitypackage. Place the Adaptive prefab in your existing world, set Width/Length on its root, use Tools > Aftergrass > Apply selected adaptive field settings, and save your scene. Full paths and upgrade steps are in the guide. The sample is not a complete VRChat world. The Adaptive field is a flat rectangle, not an automatic terrain-conforming surface. Use positive scale and level placement. Field size affects the number of tiles, so start with your venue's actual dimensions. Android/Quest and URP/HDRP are not supported release targets. Back up before updating and keep customised assets outside the package folders. Existing 1.1.0 Adaptive users should use the updated prefab and reapply their settings, rather than replacing only the script while retaining an old tile layout. The optional post-processing Profile requires Unity Post Processing 3.4.0 and your own camera/volume setup. Grass does not require it. USAGE TERMS Aftergrass is created by 萝北来信 / LuobeiLetters.
