Hi everyone - I am struggling with a glitch in 3D Viewer. Briefly, I am trying to make a simple 360 degrees rotation of a z-stack and as soon as I approach the 180 degrees point, it seems like the transparency or maybe the threshold of the images changes. Needless to say, I have tried to tweak with the transparency and threshold of my stacks w/o much success. What I noticed is that this problem appears only in z-stacks that I have appropriately scaled for pixel size. If no scaling has been made, things “seem” to work OK. Help??
