Archive tab with options for creating an Arnold Scene Source file (instead of a rendering)


Arnold Scene Source (.ass) is the native scene definition format, stored in human-readable, editable ASCII files.

Exporting To .ASS/.USD

MAXtoA lets you export scenes to .ass files  and .usd (.usda and .usdc) files that can later be rendered outside of 3ds Max with kick (a multi-platform, command-line utility) or used for rendering via proceduralsprocedurals. It  It can be found under the Archive tab in the Render Setup. The  The window will show some Arnold related options.

Note

If the options are grayed out, it is because you are in ActiveShade. If you change to Render Production, they should be visible. Alternatively, you can export an a .ass file from the File> Export menu.

Info

You can also Export an Arnold Scene Source file through the normal export options - simply choose the option and define your file name. You'll then get a dialog box with export options:

usd File  

You can export your model as a procedural via this option. The archive is saved as an (.ass/.usd) file. Arnold Scene Source (.ass) is the native scene definition format, stored in human-readable, editable ASCII files. MAXtoA lets you save scenes to .ass/.usd files that can later be rendered outside of 3ds Max with with kick (a multi-platform, command-line utility) or used for rendering via Proceduralsprocedurals.

Nodes Types

You can also specify which of the following types of nodes are included in the .ass export:

Options

Use Binary Encoding

Info

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

Relative

Uses relative path names (default)If set, the shader/property/visibility assignments will be relative to the namespace the shape is in, otherwise, the assignments will contain the full path to the shape. For instance, if a sphere named 'sphere1' resides in a procedural 'my_proc', the full name would be 'my_proc/sphere1' and the relative name 'sphere1'This makes it possible to assign the look to another procedural with a different name.

Use Current Selection

Uses the objects currently selected.
