Use Binary Encoding


Use Binary Encoding does not affect the USD format. It depends on the extension (usd/usda/usdc). .usda is ASCII, therefore the binary flag does not apply.


Specify whether binary encoding is used to compress large arrays ( bigger than 16) containing float in their components. They are encoded into a more compact ASCII representation (b85), leading to smaller files and faster load times, while still being mostly human-readable.  Also, the binary encoding has exact 32-bit precision, whereas without this binary output floating-point values are truncated into at most 8 ASCII digits (e.g. 1234.5678). The encoded arrays are indicated by prefixing the array type with "b85" as in the example below. POINT2, POINT, and VECTOR arrays are encoded. 16 float

Expand Procedurals

procedural generates Arnold nodes. This option lets you save the generated nodes in the .ass instead of just saving the procedural and its parameters.
