Summary
While legacy v1.8 assets featured dynamic, responsive wind physics, the current modern foliage assets used in Save the World missions fail to scale with the storm intensity.
Despite the worldstate indicating high wind speeds (Storm Category 4), the tree meshes remain largely static or maintain a default lowintensity ambient sway.
This is a regression in environmental fidelity caused by broken shader parameters in the transition to UE5

What Type of Bug are you experiencing?
Assets
Steps to Reproduce
Load into any Save the World mission (Stonewood/Plankerton/Canny Valley)
Observe the foliage (modern Pines and Oak remodels during a storm phase.
Compare the visual wind intensity of the trees to the HUD/Skybox weather indicators
Note that the vertex deformation (Max Rotation/Speed/Radius) does not scale, leaving assets static while the rest of the environment suggests a heavy storm like the remaining legacy assets
Expected Result
Foliage assets should dynamically respond to the mission’s storm phase. The Wind Shader logic should be restored to match the legacy 2017 standards, where trees showed significant swaying and rotation during high intensity weather events.
Observed Result
Modern foliage assets lack the dynamic scaling of wind intensity, Parameters for vertex displacement (specifically Max Rotation, which historically stood at 1.28 for highwind states are either capped or not being called by the global weatherlogic.
This creates a massive visual disconnect and a “lifeless” world environment

Additional Notes
Inspection of the current shader logic suggests that the dynamic scaling for Speedtree windparams is disconnected from the global STW weather. Restoring the legacy vertex wind values is essential for the atmospheric soul of the game.
