| Empty preview | Output wiring / Auto / curves only | Connect mesh or instances through the final join; Build and Focus. |
| Only twigs | Children do not include parents | Join trunk and each branch order before Skin. |
| Missing leaves | Both Foliage inputs, Count, Size, MinLevel | Connect Twigs and Leaf, use positive count/size and enable preview Foliage. |
| Wrong scale | Metres, Size multiplier, WorldScale | Use graph metres and WorldScale 100; do not convert twice. |
| Value edit does nothing | Wired input or disabled override | Edit its driving variable, or enable the actor override. |
| Seed has no effect | Local Seed inputs not wired | Connect GET Seed to relevant generators. |
| Same Seed, different result | Fresh Random or changed graph | Remove Fresh Random for repeatability; compare identical graph settings. |
| Disconnected roots | TrunkRadius / moved base | Share the trunk radius, keep the base anchored and inspect from several angles. |
| Faceted relief | Skin sampling versus Flute detail | Reduce relief or increase Skin.Sides; Trunk.Resolution is different. |
| Rectangular/cut leaves | Material and atlas layout | Match prototype, mask, grid/cell range and two-sided shading. |
| Canopy disappears edge-on | Flat cards / high FaceUp | Try Cross/Star, lower FaceUp and inspect from the side. |
| Grass resembles a bush | Width, arch, spread and scale | Use narrow Frond blades and unskinned support curves. |
| Mesh ignores Seed | Fixed mesh versus graph actor | Use the graph actor, or edit and re-export the mesh. |
| LOD unchanged | Unwired LOD Table | Connect table outputs to numeric consumers. |
| Missing packaged plant | Bake, cook policy and saved references | Bake for Use Baked Mesh, save assets and include the map. |
