Would appreciate a response to this.

Hi there, how many descendants does this model have? The preview you are referring to is expensive to render with very large models, so we recently limited its visibility to ensure this UI functioned smoothly. This should not affect the eventual thumbnail you see after upload, but we would like ensure this is clear and there is some way to view it.

This occurs with things as simple as single parts, so I’m sure that’s not the case.

Can you please DM me an example model where this occurs?

Sure, I have a model that I’ve always experienced it on.
As for a single part, it doesn’t seem to happen all the time.

Hi again, this is a new, intended behavior to preserve performance in the UI. The thumbnail in this context is dynamically rendered in a ViewportFrame. Hovering over the warning icon has an explanation.

Oh, okay, thanks! I thought it was unintentional. Thanks for the clarification!
