    Hello all,

    i need to get the LineObject* to a deformed Spline.
    I tried to use GetDeformCache() but seem not to work.
    How i do that?

    Thanks
    Renato T.

    At what point in the pipeline are you trying to get it? It is not always possible (or safe) try and use the cache (i.e. deformed states etc.).

    i'm using it in a deformer (pathdeformer) in ModifyObject.

    Sorry to say but you are going to have the same problems as with the currentstatetoobject. That function is running during the cache build, which means the spline deform may not be available (it depends on the hierarchy, it may have been built before your object is called).
    You would have to do the same sort of workaround as with the currentstatetoobject, grabbing it before the cache build or dumping a clone of the spline into a dummy document.
    The cache is not actually intended to be accessed other than in very specific parts of the pipeline (drawing is what it is actually for). Generally it can be very unsafe to try and access the cache as they could either be currently building, not available or invalid.
    Making code work with the generators or deformed states is not easy (workarounds and overhead), hence why much of CINEMA actually only directly uses polygons or splines.

    Ok David.. i need to find and understand your workaround about currentstateofobject :(

    thanks for now, i'll put my head soon on this.

    Just to make sure I was clear :)
    If you want to try and use the object in the hierarchy itself then you will need to call CURRENTSTATETOOBJECT outside of the cache building (just before it).
    If you want to do it during cache building (which is probably easier), then you need to clone your object first. With a clone you could call CURRENTSTATETOOBJECT or MAKEEDITABLE (for a clone either is fine).
    I'm told the clone method is known to work ok and isn't much overhead.
