Shapespark assumes a real-world scale of imported models: 1 meter in the model should correspond to 1 meter in the real world. A camera that barely moves or moves too fast indicates a problem with the model scale. Such a model should be rescaled in the 3D modeling program.
For models imported to Shapespark via FBX or OBJ that use the real-world scale but do not use 1 meter as the basic unit, a different basic unit should be selected in the Shapespark import dialog (1 cm, 1 mm or 1 inch).
