Introduction

Mesh Morpher builds and reshapes meshes with a node graph. You place nodes, wire them together, and each one does a single job: load a file, decimate, unwrap, sculpt, bake, write an FBX. The graph is the recipe, so the same sequence runs again tomorrow on a different asset without you repeating a single click.

This section documents the node library, node by node. There are over 300 of them across 41 categories, and every page here describes the pins, the settings and what the node actually does with them.

Two products, one node library

They are the same tool wearing two coats. The node library, the graph editor, the sculpt brushes, the Python stage and the .mmgraph file format are shared, so a graph built in one opens in the other. That is why one reference covers both.

Mesh Morpher Classic is a separate product: the original morph-target toolkit for Unreal Engine, with its own runtime module. It is not a node graph and it is not documented in this section.

What a graph is, and what it is not

A node is one operation. It has input pins on the left, output pins on the right, and a settings list you edit in the Details panel. Wires carry meshes, weight maps, textures, transforms, landmarks, deltas and plain numbers between them.

What surprises people coming from other node editors is that a graph is not a timeline and nothing runs continuously. There are two kinds of node and it is worth knowing which you are looking at:

Three more habits are worth forming early:

• Select a node to look at it. The viewport shows the output of whatever node is selected, so clicking your way down the chain is how you find the step that went wrong.
• Every node carries its own documentation. The book icon on a node opens View node documentation without leaving the app. These pages are the same material, indexed and cross-linked.
• Undo covers the whole graph. Wiring, node settings, sculpt strokes and paint are all one transactional history.

Finding your way around

The sidebar lists every category. If you know what you want to do but not which node does it, start here.

What you need to run it

Mesh Morpher checks your graphics device on startup and tells you plainly if something will hold it back - an integrated card sharing system memory, a driver on the known-problem list, or a driver old enough to have shader-compilation bugs. Sculpting and the GPU deformers need real graphics hardware; the rest of the library does not.
