This is because of the world volume shader. See the migration process notes.

But that does raise the question whether or not we should update the files.

Converting the volume, there's still a distinct change in look and feel. The warning about this requirement is also really not obvious at all in the GUI. Loading these scenes just looks broken unless one is staring at a console where this warning is printed.

I think so, yes. But as v2 . We can then add a note about it needing Blender 4.2 to open properly (I suppose fixed 4.2 files won't render properly in 4.1? Haven't tested).

But yes, I'd say fix the files, re-upload as v2. Keep the old one around and we can link in the description "See v1 for Blender 4.1 and older" or similar.

Hi, can confirm.

whether or not we should update the files.

Same applies for #124183 / #124175 / #124174 ?

One concern I have in this is that the recommended treatment of an existing file does not, even closely, match the original. See the wanderer, for example. Even after converting the volume, the scene is nowhere close to the original and it seems as though the user is left to figure it out themselves....

@phil.stopford this is a bug that just disappears if you refresh the view (rotate or just playback the animation). There is a missing refresh for some reason. The content is correct after the conversion.

Neat. Is that already tracked in a different ticket? I admit I had tried nudging the wanderer scene and it didn't seem to update, hence my concern, but I can see it did update in the tree creature scene after a change of view and wandered was also behaving similarly this morning.
