Hi Flavien, thanks for following up. Yes, that is where I got the exporter, using the Rhino 4.27 windows preview, and UE is 4.27 preview 4. Rhino 7 is also fully updated. If I hit connections in the Datasmith Rhino toolbar, it says “No connection found. Waiting for a Datasmith Direct Link connection to be established. Please start an application supporting Datasmith Direct Link such as Twinmotion or Unreal Engine.” I have UE running at the time. Also tried with Twinmotion running. That’s as far as I’ve gotten with direct link. I’ve also found that my rhino model won’t export. I’ve tested with other simple models, and they will. But the large complex model that I’d like to export won’t. Whereas with a simple model, when I hit export I get a progress bar across the bottom while it processes, with the large model it just instantly completes and creates a ghost file. A “0 bytes” .udatasmith file shows up in the recent files list, but when I open the folder it should be in it is empty. I’ve tried troubleshooting, trying to identify what is throwing the export process, but still no idea. I just know that if I delete enough of the model contents, it starts exporting again. Is there some sort of limit on geometry content, or file size, etc?
