Yes. Replace the ui.py here with the one from the attached zipfile.
That is shadow check box ?
No. That is without. The shadow checkbox is gone. Don’t ask me why. The Blender devs did it. I just implement their code here.
I have of course searched if they have placed the feature elsewhere under another name. But without luck. And the prop for the shadow checkbox is gone in the code. So there is nothing that i could do. Since i rely at the Master code, not the Release Version code.
