Force Mesh creation at runtime?

[Elenesski]

How do I force the creation of a mesh at runtime?  If I use a generator, the mesh gets created if I run the creation through a co-routine, but how do I force the mesh to be created without a co-routine?

Like answered by mail: Call CurvyGenerator.Refresh(), then use the CreateMesh module's SaveToScene() method to "extract" the meshes.

This code does not work, unless, I put it into a co-routine with a 0.1f second wait.

Code:

   // Create the spline
   var GENERATOR = CurvyGenerator.Create();
   var SHAPE = Rails[0].CopyTo(GENERATOR);

   var PATH = GENERATOR.AddModule<InputSplinePath>();
   var EXTRUSION = GENERATOR.AddModule<BuildShapeExtrusion>();
   var VOLUME = GENERATOR.AddModule<BuildVolumeMesh>();
   VOLUME.SetMaterial(0, RailMaterials[1]);
   VOLUME.MaterialSetttings[0].KeepAspect = CGKeepAspectMode.ScaleU;
   var MESH = GENERATOR.AddModule<CreateMesh>();

   // Wire the Generator Parts
   PATH.OutputByName["Path"].LinkTo(EXTRUSION.InputByName["Path"]);
   SHAPE.OutputByName["Shape"].LinkTo(EXTRUSION.InputByName["Cross"]);
   EXTRUSION.OutputByName["Volume"].LinkTo(VOLUME.InputByName["Volume"]);
   VOLUME.OutputByName["VMesh"].LinkTo(MESH.InputByName["VMesh"]);

   // Create the spline
   PATH.Spline = CurvySpline.Create();

   GENERATOR.Initialize(true);

   // ... logic to add points to SPLINE

   GENERATOR.Refresh(true);
   var CREATED_MESH = MESH.SaveToScene(myGameObject.transform);

   // CREATED_MESH is null

What does "var SHAPE=Rails[0].CopyTo(GENERATOR)" is supposed to do?

Edit: Nevermind, should know my own API better

You shouldn't need to make your shape spline a managed spline (that's what you do with copying it into the CG space). I just noticed your other post, will continue there...

[Elenesski]

Rails[0] is a shape inside of another generator created within the editor.  The thing is, the code runs fun if I put it into a co-routine and let the system run though a bunch of frames, but doesn't work if I run it straight.

In retrospect, I may have done this because I couldn't figure out a way to create the shape at runtime.  I could create a shape consisting of pre-fab elements like circles and boxes, but how do I create a spline and tell Curvy to extrude it along the path ... all at runtime?  There was no sample in the example code that I could find to do that.
