MetersPerUnit

These files show how the metersPerUnit stage metadata works.

MetersPerUnit = 1

metersPerUnit = 1

MetersPerUnit = 10

metersPerUnit_10.usda

metersPerUnit = 10

MetersPerUnit mixed

metersPerUnit_mix.usda

This stage sets metersPerUnit = 100 and also sublayers metersPerUnit_1.usda and metersPerUnit_10.usda with different values.

USD does not auto-scale layers with divergent metersPerUnit. As a result, all three cubes in this file have the same size.
