I have a set of reference images for a scene that combines rugged, mountainous terrain with a simple fort, and I need the base geometry built in Blender. No materials, UVs, or texturing are required—just clean, well-organized mesh work that matches the images closely enough for me to take it further later. The terrain should read as steep and natural, with slopes, cliffs, and plateaus that follow the photos. For the fort, I only need basic geometric forms: walls, towers, gatehouse, and any main platforms blocked out at the correct scale. Think solid, low-poly shapes ready for detailing later rather than ornate architecture. Please deliver a single .blend file with logical naming and hierarchy so I can jump straight into the next stage. Let me know your estimated turnaround and any questions about the references, and I’ll get the image pack to you right away.
