Detailed 3D Landscape Modeling

I need a realistic, fully textured 3D landscape that can slot straight into an architectural visualisation workflow. The scene should be built from the ground up in your preferred DCC (Blender, 3ds Max + V-Ray/Corona, Cinema 4D, or similar) and delivered in a clean, well-organised file with all supporting textures and shaders.

Key goals
• Capture believable terrain contours and surface variation suitable for aerial and ground-level camera moves.
• Optimise poly count so the file remains lightweight without sacrificing visual quality.
• UVs laid out logically so materials can be edited easily after hand-off.
• Final deliverable: native file + FBX/OBJ export, texture folder, one beauty still (4K) for review.

You’re free to suggest natural features—lakes, rivers, mountains, dense vegetation, or a mix—so long as the result feels cohesive and production-ready.

I’ll provide reference sketches and a rough site layout once we kick off. Please outline your proposed workflow, software, and estimated turnaround when you reply.
