It seems odd that an item deleted from web server (with intent) would continue to be rendered in scene - interface indicates file is missing on remote server, using cached copy. I, for one, do not think this is desired behavior - if I’ve deleted an item from server, I expect it to be gone in scene even if I didn’t delete it in scene via interface. Since interface is getting a 404 it knows proper response is item no longer exists (thus the error message in debug). If Interface couldn’t reach asset holding server then I could see it using cached copy.
Another item - minor. Interface previously went into an idle mode when its window wasn’t active – idling down to render rate of 15(ish) FPS. Currently on Windows and Linux with latest code it continues to render at full rate regardless of window being active or minimized.
