Yes, I realized how you can do the fancy little trick in the command bar to set the assetUrl, but that’s a pain in the butt when it comes to testing my place. Is there any reason that the assetUrl isn’t set for Test Server?
What methods are you calling? I just tried InsertService::LoadAsset from a test server and it worked fine. You may have to wait a second or two for the CoreScript which sets those URLs to load though.
