I have been a long time out of the loop with Octane, but having upgraded to this version (4.01.1.88) am noting that the material selection using eyedropper in viewport is not working properly at all. Over most of viewport image, no material can be selected at all, and where I can get a response, the wrong material is selected.
I suspect there is a DPI scaling issue with the ArchiCAD plugin viewport? The behaviour I am seeing is consistent with the eyedropper selections being sampled from a different location on the image than where the mouse pointer/eyedropper is being displayed - whether this difference is a consistent linear offset from mouse pointer or a scaled difference I am not sure.
I do know that Microsoft changed the way Windows 10 handles UI elements (like mouse pointers) within applications, early last year, supposedly to make them scale better for large format displays
In my testing, the issue indeed goes away when I change windows display scaling from 150% (default) to 100% - though of course on any modern workstation with a standard 4K display, this is not a very useful or workable solution, as 100% display scaling leaves most windows UI elements and text near-invisibly small.
Another related bug is that the viewport image does not correctly fill the extents of the ArchiCAD viewport window unless display scaling is dropped down to 100%.
