I have successfully built my whole house model, not bad for a non computer type of guy, here is what I am running into, when I open a sequence (which has my pixel tree in it) I add the whole house in the display model, then I copy and paste, hit save, go to preview and hit play, on the playback it is showing the right side of my display as very faded, can hardly see it. Now when I open another seq and go to display models I check off each individual model and then copy and paste, hit save go to preview and hit play, everything works perfectly, anyone else experiencing this or just me?
