Heroes 7.5 Ultimate Edition mod for Might & Magic: Heroes VII.

Colleagues, sorry for addressing a slightly off-topic question, but could you tell me how to extract landscape textures (e.g., desert, grass, snow, etc.) from Might & Magic Heroes VII?
The other day, I was browsing through the game's archives using Umodel, but I couldn't figure out where these textures are located.

Thank you for your attention.
