Ugly shadow appearing through glass material

[Double Doppler 10]

I have assigned some faces in a common element a glass material in a resolution LOD. The model has a shadow LOD. My problem is that the shadow outline appears through part of the glass and ruins the reflective look. What is going on here? How can I fix this? Can I solve it through modifying face properties or is it a problem with the glass RVMAT?

EDIT: I think the correct term for this is "shadow artifacts". I have tried adding "NoZWrite" in the render flags array to remedy this but the shadow still displays through the glass RVMAT.

Tried reversing every face in your shadow LOD ? (Select All, W key)

NOTE: Buldozer has a habit of not providing correct updates after you make changes ...... sometime you have to close O2 & buldozer and reopen before some certain changes become visible.

I have tried reversing the faces - it doesn't solve the problem, just renders the shadow artifact in a different way (there is z-fighting in the outline of the artifact). I don't want the shadow to render through the glass.

Here are pictures of what I am talking about:

Property; lodnoshadow = 1 ?

Also, tried making the shadow model just a fraction smaller than the Res LOD ?

I added the property lodnoshadow and set it to 1 but the problem still persists.

I did scale it down a bit - it solved the shadow appearing on the other material (the taser body) but the glass remained affected.

I had to set it to a ridiculously small size in order to stop it appearing on the glass.
