    Okay so I have a function that worked 100% in R11.5 but does not do anything in R12.  The function rotates the active object at the speed specified based on the current framerate.

    I assume that somehting has changed in the timeline/ CTrack ...     Here's is the code that worked in R11.5.   Does anyone see any reason why it wouldn't work in R12?   I'm not asking you to debug the whole thing.  I am asking you to look to see if there is something in this code that has changed in the r12 sdk..   That will at least help me pin point what I should be looking at.

    Thanks so much,.

    PS this code compiles fine in R12 but does not rotate the object at all.   :)

    Solved this.   I just declared,

    DescID idRotY = DescID(DescLevel(ID_BASEOBJECT_REL_ROTATION,DTYPE_VECTOR,0),DescLevel(VECTOR_Y,DTYPE_REAL,0));

    and replaced all DescID calles with   idRotY
