Make sure you have all layers showing, any layer , for me it seems to only effect the layers that are visible.
You can be certain to select all of them , copy then delete. Comes in handy if for some reason the coder has inserts and light on various layers, esp. when they should be in that same group.
make sure all layers are visible, past (ctrl V), then right click on onw in the group and send to back. then lock them.
Also,, the bue light shining through the top surface, above your targets, set the light to Ordered HaloGlow, it will stop that, you may need to set light to 33% as well, and with this also make sure the light is actually behind the surface(s).
One thing that sucks is there isnt a way that i know of the tell what lever (z) 3d aspect the order is.
you can have 3 surfaces, one surface on layer 1 , a second on layer 2, and a third on layer 3.
yet who original coder may have the 2nd surface on layer 2 the one that needs to be on top of surface 1 and 3.
dont assume the ibjectys or surfaces and stacked by the layers in the editor,.
One would thing that whoever codes a table would make stacking
in order per layer, but thats not always the case. There is no easy way to tell which one is supposed to be on top, this can be a bitch
if you get things out of order editing.
