Graph Mesh Generator
The Graph mesh generator uses a PopcornFX nodegraph to compute the properties of each vertex on a source mesh (either procedural from a list of builtin shape types, or from an external mesh asset).

When enabled, all the normals will be automatically recomputed from the mesh geometry. |
|
|
When enabled, all the tangents will be automatically recomputed from the normals & UVs. |
|
|
When enabled, normals will be smoothed across UV seams. |

Vertex Graph
The vertex graph is run once per vertex of the base generated mesh, to compute the new properties of this vertex.
The base vertex graph consists of an input template MeshGeneratorArgs, which outputs the various properties of the vertex, and an output template MeshGeneratorOutputs, which expects as an input all the properties to rewrite into that vertex. Pins that are not wired will keep the original property of the vertex.
Current Limitations
-
You cannot make local templates
-
You cannot use custom attributes
-
The simulation will be one-shot, it cannot be iterated over multiple frames to make a simulation converge using previous vertex values
Available Inputs
