Got my model train into houdini for retopo but Im not seeing a way to mirror the quads to the other side. Same for subdividing and creasing. Putting the nodes after the topobuild doesnt seem to give me the results i want. Quad mesh isnt snapping and reshaping to the input geometry. Is there a way to loop back into topobuild?
Hopefully I understood your problem correctly You can mirror your one side topobuild by using a mirror sop. Then use another topobuild sop to unite both sides.
