Overgrowth - documentation

INSTALL

Edit > Preferences > Add-ons > drop-down arrow > Install from Disk..., pick overgrowth_v1.0.0.zip (don't unzip it), tick "Overgrowth". Requires Blender 5.2 or newer.

WHERE

3D View > Sidebar (press N) > one99addons tab > Overgrowth. Also in the Object menu > Overgrowth.

QUICK START

• Select the objects (walls, props and the ground together is best).
• Pick a Climate: Temperate, Autumn, Tropical or Dry.
• Click a growth stage: Damp, Mossy, Overgrown or Jungle Ruins.

Click another stage at any time: objects that already have Overgrowth just get the new settings.

MAIN PANEL

• Real Growth: also grow real ivy, moss carpet and ground cover (geometry, through a modifier). Off = material layers only, much lighter.
• Unique Copy: if a material is shared with objects you did not select, the selected objects get their own copy. Also needed for materials linked from another file.
• Remove Overgrowth: takes it all off. Links, nodes, slots and modifiers come back exactly as they were.
• New Pattern: a new random pattern (seed) for the selected objects.
• Copy to Selected: copies every setting of the active object to the other selected objects.

GLOBAL

Growth (master amount), Pattern Size, Seed, Per-Object variation, Bump.

MATERIAL LAYERS (painted on top of your material)

• Moss: amount, coverage (0 = tops and creases only, 1 = sides too), patch size, colours, fuzz.
• Lichen: round colonies in two colours.
• Damp & Algae: wet darkening in creases and low areas, dark streaks running down.
• Mud & Puddles: bare muddy patches with standing water. The grass and leaves avoid exactly these patches.
• Soil: rough earth on the ground, mud splashed on the bottom of walls.

REAL GROWTH (geometry)

• Moss Carpet: amount, thickness, drape (moss hanging down over the edges) and drape length, cushion size, fuzz (tiny shoots), spore stalks, colours.
• Ivy: amount (number of stems), height, drape (stems pouring down from the top edges), branching, leaf density and size, stem thickness, old and young leaf colours.
• Grass: amount, height, patchiness, share of dry blades, colours.
• Ground Litter: fallen leaves and their colours, twigs, pebbles, ground moss, Cover Height.
• Seed & Quality.

TIPS

• Ground cover only grows on up-facing faces close to each object's lowest point (Cover Height, 0.3 m by default): the ground and the foot of walls, not the top of a table.
• Slow viewport: lower Quality or untick Real Growth while you work.
• Objects in real-world size give the best results (sizes are in metres).
• Every part is a named node group (Overgrowth · Ivy, Moss Carpet, Ground Cover...) if you want to look inside.

LIMITS

• Curves and text objects get the material layers only (real geometry needs a mesh).
• Very dense scenes render faster in Cycles than in EEVEE.
