Hey El and Kevin.  I’ve been trying to fix the flickering glass problem, and may have actually gotten rid of most or all of it.  I didn’t want to mess with the aliasing settings to increase render time, so I just did a lot of experimenting with the texture itself and the actual model of the column.  Here is what I’ve landed on.  I’ll render some of the other scenes that have a moving camera using the new settings to see if the fix works on them to.
