Graph plumbing: grouping work into subgraphs and other helpers that shape the graph itself rather than the mesh.

When to use it

Pulls one mesh out of a Mesh Array by index and reports the array's length on a second output. This is the way back from batch work into ordinary single-mesh graphs. Wire the array in, drive Index from a Math node, and everything downstream sees a normal mesh.

It recomputes whenever the array or the index changes.

When the array's bytes are parked in the .mmgraph file, only the element you ask for gets pulled off disk and decompressed. Indexing into a forty-head array does not wake the other thirty-nine.

Pins

InputsOutputs

Pin	Type	Description
`Array`	Mesh List	The array to read out of.

Pin	Type	Description
`Mesh`	Mesh	The mesh you asked for, on a normal Mesh wire.
`Count`	Whole Number	How many meshes the array holds. Still correct even when Index points past the end.

Settings

Setting	Type	Description
`Element Index`	Whole number	Which mesh to read, counting from 0.

When to use it

Point it at a folder of mesh files, press Scan Directory, and the whole folder arrives on one wire instead of forty loaders. From there Get Mesh Array Element reaches in for one, or a headless -mmrun -mmin sweep processes the folder one file at a time.

Pins

Outputs

Pin	Type	Description
`Array`	Mesh List	Every mesh in the folder on one wire, sorted the same way on every machine.
`Count`	Whole Number	How many slots the array has, empty ones included.
`FailedCount`	Whole Number	How many files would not import. Anything above zero means the batch is short.

Settings

Setting	Type	Description
`Source Directory`	Text	Full path to the folder you want to read. Nothing is ever written there.
`Extension Filter`	Text	Which file types to pick up, separated by semicolons and written without dots, like `obj;fbx`. Leave it empty to take everything readable. Upper or lower case makes no difference.
`Recursive`	True/False	Also look inside folders within the one you picked.
`Max Files`	Whole number	Stop after this many files. 0 means no limit. Worth setting when you are not certain whether that folder holds forty meshes or ten thousand.
`Failure Policy`	Choice	What happens when one file will not import.
`Use T0 Pose`	True/False	FBX only. Bring in the bind pose instead of the first frame of animation.
`Coordinate System`	Choice	Handedness the files were exported with. Pick the wrong one and every mesh arrives mirrored. OBJ and FBX only.
`Front Axis`	Choice	Which axis points forward in the source files. OBJ and FBX only.
`Up Axis`	Choice	Which axis points up in the source files. Get it wrong and the whole batch comes in lying on its side. OBJ and FBX only.
`OBJ Sections From`	Choice	Which statements split an OBJ into material sections. OBJ marks materials with `usemtl`, so parts that reuse one material - or name none - would otherwise arrive merged into a single section. OBJ only.

Reroute

A knot on a wire. Values pass through unchanged, so a long route can bend around other nodes. Purely visual: no cost, no copy, no effect on evaluation.

When to use it

A knot on a wire. Values pass through unchanged, so a long route can bend around other nodes. Purely visual: no cost, no copy, no effect on evaluation.

Double-click an existing wire to drop one in place rather than adding it from the picker and re-wiring by hand.

Its pins start as wildcards and take on the type of whatever they are connected to, so wire colours stay correct and type checking stays exactly as strict as it would be without the knot. Remove the last wire and it goes back to wildcard.

Pins

InputsOutputs

Pin	Type	Description
`Value`	Any	Anything at all. The knot does not touch it.

Pin	Type	Description
`Value`	Any	Exactly what went in.

Subgraph

Collapses a group of nodes into one card so a big graph stays readable.

When to use it

Collapses a group of nodes into one card so a big graph stays readable.

Settings

Setting	Type	Description
`Subgraph Name`	Text	What the group is called, on the card and in the breadcrumb trail across the top of the graph.
