I copied the 3DSceneColors file from the SideFx program files into my windows docs/18.XX folder under the config folder and made changes to the colors and alpha values related to the cplane:
CplaneColor: 0.0 0.0 0.0 # non-selected active construction plane
...
...
CplaneAlpha: .....
CplaneLineAlpha: .....
etc.
However, after making changes and restarting a client of Houdini, no changes ever gets reflected in the scene.
Do I need to make some changes to the config file too? So that it will look at the copied 3DSceneColor file as a priority one to use?
