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.
