Wind¶
Foliage sways and bends away from the player (MM_KurinAssetFoliage_01a); flags and tarps wave (MM_KurinAsset_01a). Each switch off = no cost.
Foliage wind¶
| Switch | What it does | Needs |
|---|---|---|
| Use Wind? | Main bend | Vertex color R (0 root, 1 top) |
| Use Wind Height Mask? | Bend by height, no painting: good for grass | Wind Mask Height (cm) |
| Use Branch And Leaf Wind? | Branch sway, leaf flutter | Vertex color G branch, B leaf, A phase |
| Use Global Wind? | One wind for the level from MPC_KurinWind (ships in _Core/Materials) | — |
| Use Interaction? | Bends away from up to 4 characters or vehicles | Blueprint below |
Interaction setup¶
Character Blueprint, Event Tick (Tick Group Post Physics), on MPC_KurinWind:
- Copy Interactor 0 into Interactor 0 Prev (keeps TSR and motion blur clean).
- Set Interactor 0 = actor location (RGB) + radius in cm (A, e.g. 80). NPCs use Interactor 1–3.
- In the foliage MI: Use Interaction? on, tune Interaction Strength.
Cloth Wind¶
Use Cloth Wind? on MM_KurinAsset_01a, then Cloth Amplitude. Paint vertex color black (attached edge) to white (free edge).
Tips¶
- Storms: change Wind Strength in MPC_KurinWind from a Blueprint.
- Cloth: set World Position Offset Disable Distance on the mesh component (3000–5000 cm).
