I am trying to do what is described in this old thread.
Basically I have a c4d file on disk that I have the Filename for, I then start a HandleMouseDrag from my GeUserArea and want to be able to drop it into the Viewport or Object Manager and have it load.
So far with my testing none of the following types work.
So I have instead tried doing it via a different approach. I am loading the document, grabbing some models from the scene, adding them to an AtomArray and then doing a HandleMouseDrag using the type DRAGTYPE_ATOMARRAY. But this only seems to work when dropping into the Object Manager. If you drop it over the viewport then nothing happens.
Is there anyway to be able initiate a drag drop from a GeUserArea and have C4D merge the file that is dropped? Or is there a way to manually do it an have the Viewport accepted the dropped content? Needs to work in R20 to 2023.
