Hi,
I'm trying to create a track etc, for FocalLength.
Via: op->FindTrack, InsertTrack, etc.
But How do I find the (descID) needed.
Could it be something like descID = DescID(DescLevel(ID_CAMERA_ZOOM,0,0) ?
Thanks.

DescID(DescLevel(CAMERA_FOCUS), DescLevel(0, DTYPE_REAL, 0))

Usually, you can use the description resource (like Ocamera.res) to get at the description ID definitions. You might also want to set the CAMERA_APERTURE along with this.

In this case, the second DescLevel() exists because I use a generic track/sequence/key creation function. Like this track code section, where id = CAMERA_FOCUS and sid = 0:

  
     // Find Object Track by id/sid  
     if (!(track = obj->FindTrack(DescID(DescLevel(id), DescLevel(sid, DTYPE_REAL, 0)))))  
     {  
          if (!(track = AllocValueTrack(obj, DescID(DescLevel(id), DescLevel(sid, DTYPE_REAL, 0))))) return ErrorException::Throw(GeLoadString(ERROR_MEMORY_TEXT), "CreateKeys.track");  
          obj->InsertTrackLast(track);  
          doc->AddUndo(UNDO_NEW, track);  
     }

Wauw, thanks Robert, its working allright.
I'm recording position and rotation tracks with a similar generic function.
Strange thing is: replay position tracks seems a heavy load.
Deleting the recorded position tracks (HPB) on the fly, immediatly causes a jump up in framespeed. (no matter display quality).
As said I use the same function for recording tracks
