Visibility bug

[coilbook]

Hi If you make a box with glass material and clone it and turn one of the boxes visibility 0 It is like still there during rendering if it is located in exact the same place as a visible box. This is a problem for rayfire glass demolition since prefragmented glass is invisible until rock hits it but since it is located in the same space as glass before impact octane renders artifact lines. Please take a lot this bug Thanks

On a picture you see a large sheet of glass with prefragged chunks of glass. But they are set to Visibility 0 since rock has not hit them yet even though they are showing up in rendered image. only happens if they are located in the exact same space as whole glass
