Hello,
If I understand correctly, you want part of the hair to be converted to mesh and keep the rest as normal hair, right?
We are working on a branching system to allow the users to do exactly what you ask in an intuitive way, but this is already possible if you know how to use the Node Editor. Ornatrix nodes are just regular Maya nodes.
For now, you can use the following MEL command to create a new branch with MeshFromStrands on top, then specify the strand group you want to be affected. The resulting stack is composed of two Ornatrix shapes, one if a regular hair object and the second is a mesh object, but they are still connected with each other.
Just select the operator from which you want to convert the hair to mesh and run this command in the script editor:
string $selectedNode[] = `ls -selection`;
OxAddStrandOperator2( $selectedNode[0], "MeshFromStrandsNode", 1 )
