Wow. Works flawlessly. Tested on different scenarios with different hierarchy and nested objects. Also - as expected - everything is 'taggable' in Layout. Thank You very much. [image: zeyu_itsflawless.png]

Did you try Animator? I've used it in the past to animate shadows over time. [image: 7gKxMQs.png] Click image below to play... [image: JKI1_shadow.gif]

Thank You for your help. Registry entries seem to be a problem. Generally things work nearly perfectly now. Nearly, because after cleaning up registry some toolbars refuse to work. I will install non-working plugins once again. But performance boost is undeniable. Thanks again.
