Summary

Hi,

First, the base surface of ox ground strands is defined by seven splines, and I disabled root detached for rotation.

I'm not sure if I understand this part. "Root Detached' is just to detach the guides/hair roots from the polygon mesh if you have one selected. If you don't have one selected, it should remain checked/dettached.

I intended to make a more detailed bun hair by going into ox guides and selecting one of the seven to rotate.

Did you mean by going into Ox Edit Guides and rotating the strands with the rotate tool? If so, Edit Guides requieres a distribution mesh to perform many of its operations correctly. For this, in Ground Strands, make sure to set a distribution mesh and attach the roots to it as described in the documentation.

However, the rotation was not applied as expected. I tried various methods, and during the process, when I changed the base surface of ox ground strands from splines to female hair, it worked, although the position values were significantly different. However, there were times when it did not work, and I cannot understand the reason for this inconsistency.

The spline curves cannot be a distribution surface for the groom. It needs to be a polygon mesh as described above. Check the Ground Strands documentation and videos here to learn how to approach this and to avoid the changes in positions that you just described above.

I decided to give up on this method and attempted to create groups for the hair roots using ox rotate strands. However, when I tried to assign group numbers by clicking on one root and specifying a group number, all roots changed to the same color, contrary to the expected behavior where only the selected root should change.

I think this is the same issue as above. You have to ground the strands properly for Edit Guides to work as expected.
