Check the bridge connection and report the 3ds Max scene state.

Execute arbitrary MaxScript inside 3ds Max and return the result of the last expression. Escape hatch for anything not covered by a typed tool below.

Execute arbitrary Python inside 3ds Max's embedded interpreter (pymxs available as rt). For an expression, its value is returned; for a statement block, assign to a variable named result to return something. stdout is captured and returned too.

Get scene units, frame rate, frame range, and object count.

List scene objects, each as {handle, name, class, pos, bbox}. filter matches (case-insensitive) against object name or class.

Get the objects currently selected in the 3ds Max viewport.

Select objects by handle (replaces the current selection).

Create a primitive/object by its MAXScript class name (Box, Sphere, Cylinder, Plane, Cone, Torus, Teapot, ...). params are extra creation-time properties (e.g. {"radius": 10, "height": 20}).

Set an object's world position, Euler rotation (degrees, XYZ), and/or scale.

Set an arbitrary MAXScript property on an object by name and return its new value.

Delete objects by handle.

Export the scene (or just the given handles) to disk. The exporter is chosen from the path's file extension (.fbx, .obj, ...).

Save the current scene. Omit path to save in place.

Add a modifier by its MAXScript class name (Edit_Poly, Bend, UVW_Map, Turbosmooth, ...) to an object, with optional properties.

Create a Standard material (optionally with a diffuse bitmap texture loaded from disk) and assign it to the given objects.

Set an animation keyframe on an object at the given frame number.

Create a simple axis-aligned box collision proxy for each given object, sized to its world bounding box and named {prefix}{name}. This is a generic starting point, not tuned to any specific game engine's collision format yet.
