Hi there, I started using the ModelClip leaf node to cut off parts of my scene. The weird thing that happens concerns the screen door transparency. Normally I use a transparency of 0.5 for my objects. This all works fine, until adding a ModelClip node somewhere in the scene (i attached it to my avatar). The transparancy patch changes to a very coarse grid (see attachment). The really funny thing is, when removing the modelclip (i can turn it on/off automatically) the transparancy is normal again. Cheers, Karsten
