• Efficient Geometry: Optimized meshes without sacrificing detail.

• Texture Handling: Compressed textures and on-demand loading prevent VRAM bloat.

Optimization Tips

• Use Blender's Simplify settings to cap texture resolution.

• Purge unused data regularly during workflow.

• Render in passes for complex scenes to optimize resource usage.
