I have an issue with generating previews using Batch-Generate Previews for objects larger than around 60m. The object's thumbnail appears completely transparent in Blender file browser.

Can anyone confirm this is a bug? Is there a workaround?

I am using Blender 2.79.1.

EDIT: I have reported that as a bug and it is going to be fixed soon. https://developer.blender.org/T53002

  • $\begingroup$ Check your scene/viewport/camera clipping distances, it may be affecting the previews for very large objets $\endgroup$

  • $\begingroup$ The clipping distance is set from 1cm to 1km, while the object is 60m. I even tried to enlarge the distance but no change. $\endgroup$

Wow, so I have reported the bug on developer.blender.org and it was fixed in about 3 hours!

Link with the fix details: https://developer.blender.org/rB63482a5f2e2ad76989c2d2901c1f34f2f0cb59d4

I have compiled the current Blender build which contains the fix and I can confirm the big object has now it's preview generated correctly.

This means a future public version will have this fixed as well.

Big thanks to Blender developers for such prompt reaction :)
