White & Grey Matter Brain

I’m putting together an educational package on human neuro-anatomy and I need a clean, OBJ-format brain that presents the white matter and grey matter as two clearly separable meshes.

Scope
• Purpose: the model will be shown in lectures and short videos, so it must look accurate at a classroom zoom level but does not need every microscopic sulcus. Think moderate resolution: all lobes, cerebellum, corpus callosum and brain stem should be recognisable, yet the poly-count should stay friendly for smooth orbiting in common viewers such as Blender or Sketchfab.
• Static only: no scripts or embedded interactivity—just the geometry (and optional textures) ready to import.
• Deliverable: one OBJ (or two OBJs if you prefer to separate layers), accompanying MTL, and any texture or normal maps you create. A quick turnaround render or viewport screenshot that proves both layers align correctly will help me sign off.

Acceptance
I’ll consider the job complete when I can:
1. Toggle white and grey matter on/off independently.
2. Orbit the model in Blender without lag on a mid-range laptop.
3. See all major external landmarks and internal commissures at a glance.

If you already have anatomical reference or volumetric data you like working from, feel free to use it; otherwise let me know what you’ll need and I can point you to public MRI sets. I’m ready to get started right away and will be responsive to feedback questions during the build.
