Hi, yep, just tried to use that hidden feature. It seems to work fine for me (even using it in a scene on multiple objects), but always only for single objects or meshes, but not for complete groups! Although, no problem, when selecting a single object in a group (no need to ungroup, when CRTL_CLICK_selecting). SHIFT+CTRL+CHECKMARK seems to switch object-antialias off and using SHIFT+CHECKMARK seems to switch it on again (at least in my Bryce 4.01 Win). Would like to have a radio-button for that option in the Attributes-box of an object in Bryce5. Hubert
