But are you talking about the IPR or the final rendering to disk? In the IPR window, to update the TFD animation while scrubbing you must enable the "Full.Upd" button, and to update any kind of material, including the procedurals, you must enable the "Mat.Upd" button.
In the final rendering to disk (F10), in the render target root node options panel you must enable the "Update Materials" and the "Update Volumetrics", or if this fails, render the scene in "Full Scene Reload" mode.
