Wood Grain Appearances in eDrawings

When we publish assemblies in Edrawings where parts have woodgrains, some wood grains will show correct, some will but in thewrong orientation (this aso happens when we render), and some won'tshow at all.

Sometimes when we go back to the part and re-assign the appearanceit will work but more often than not, it won't. Is there a specificway to keep the grain running the way we want it throughout?SolidworksEdrawings
