    "description": "Wersja robocza nowej koncepcji elektrycznego auta ekspedycyjnego. Obraz koncepcyjny powstał w tym zadaniu; model 3D odtwarza jego bryłę i wnioskuje niewidoczne powierzchnie. Podgląd ma kolory wierzchołków z natywnych danych i uproszczony materiał; wymaga dalszego dopracowania krawędzi, szyb i wykończenia. Eksport UV/PBR 8K nie został zatwierdzony wizualnie."
