Where do these renders come from?

[CJ H.]

I've come across a few parts in Rebrickable that have 3D renders, but I can't find the part in LDraw or in Studio.  For example:  https://rebrickable.com/parts/10164pr000...top-print/

I'm pretty sure these are not cases where there is a part (official or unofficial) and it's just under a different number.  

Does anyone have an idea where the underlying parts for these renders might come from?  For the example above, it looks like BrickOwl has the same rendering, but I haven't found any documentation on where their renders come from. 

I posted the same question on the Rebrickable forum a while back, but Simon, who was responsible for their part images, passed away recently. 

As an aside, I have found many cases where there isn't a part (official or unofficial) in LDraw, but there is one in Studio.  Why would that be?

Thanks.

Bricklink uses any 3D meshes they can find and convert to LDraw format. This would be all well if they didn't use sometimes plain stupid origin/orientations (eg. gears with off-axis origin!) thus causing LDraw import/export incompatibilities!!! See for ex. https://forum.bricklink.com/viewtopic.ph...d80b#p3951

Thanks for that.  I hadn't thought about the possibility of those images coming from LEGO.
