High-Detail 3D Gameplay Tree Model

I need a massive, high-detail 3D realistic tree model for an interactive gameplay element in an Assassin's Creed-style game. The tree will serve multiple functions: a climbing structure, a lookout point, and hiding spots. Ideally has hollowed out areas that goes from one side to the other thats large enough for additional rooms and bonus areas to unlock but not required. If there are hollowed out areas or just simply hiding spots then caps to cover them if not used for that instance is required.

For Unreal Engine 5 use.

Key Requirements:
- High detail with individual leaves and realistic textures.
- Strong enough to support climbing mechanics.
- Design should allow for scaling branches, looking out, and hiding.
-Either tree has enough polyfaces or high enough detail in the textures for trees that are generally much larger than all buildings.
- Additional branches, leaves, and roots to give appearance of varying trees

Ideal Skills and Experience:
- Expertise in 3D modeling, especially organic structures.
- Experience with game-ready assets.
- Knowledge of climbing mechanics in game design.
- Strong attention to detail for realism.
