SpeedTree Forest Trees for Unity

I’m building a temperate-forest scene in Unity and need a small set of production-ready SpeedTree assets to drop straight in. For this initial milestone I only need one, possibly two, trees—both should be mature specimens suitable for a European broadleaf forest:

• Fagus sylvatica (European beech)
• Quercus petraea (sessile oak)

Each tree must ship with its own SpeedTree .spm file and a Unity-ready package that includes: fully-authored PBR textures (albedo, normal, roughness, AO), vertex-animated wind set-up, seasonal variation sliders (summer and autumn are enough for now), and at least three LOD levels that transition cleanly. Polycount should be sensible for real-time use, and pivot points, scaling, and origin need to line up correctly when instanced in Unity’s default HDRP scene.

If you’ve already built similar assets, feel free to show a clip or screenshot; otherwise outline how you plan to capture bark, leaf, and twig detail. As soon as I can drag the package into Unity, toggle the wind zone, and see natural movement without shader errors, we’re good to go. I’m keeping this phase small, but a full forest set is planned if everything looks right.
