Simple Blender Desert Scene Creation

I’m putting together a straightforward Blender scene that shows a sparse desert landscape—think rolling dunes, warm lighting, and the subtle texture variations you’d naturally expect in sand. Nothing complex is required beyond this natural environment; no buildings, furniture, or character work.

What I expect:
• A clean .blend file that opens in the current stable release of Blender.
• The terrain and materials neatly organised so I can tweak colours, roughness, and scale without hunting through the Outliner.
• Real-time-friendly geometry—keep the poly count reasonable and avoid heavy modifiers that are unapplied.

If you prefer to add a sky texture, light haze, or a simple sun-and-sky HDRI, that’s great, but it’s optional. My main goal is a basic, editable desert scene I can build on later.
