Missing Thumbnail on twitter embeds / general thumbnail issues


(1008008) #1

Hi - I’m having inconsistent results with my twitter embeds.
Sometimes a thumbnail shows up, sometimes a blank grey thumbnail.
Is there any way to make sure ther is a thumbnail?
I have tried publc / private / draft models and all are inconsistent.
Thanks!

So - If I upload my sketch via the C4D plugin - I get a nice thumbnail.
But If I upload via FBX, I get a blank grey thumbnail.
Anyone else having trouble, or got any ideas?

I now understand that this is not to do with twitter embedding, but more a general issue with thumbnails.
Any help and experience appreciated.

Hi @1008008

If you have models that don’t have a thumbnail, you can go into the editor and click on save view. This wil generate new thumbnails. Once these are generated, it may take a while for cache to clear and for twitter to update it, so don’t expect the results to be immediate.

Hope this helps

Thanks for the clarification

You also need to make sure you don’t share the links on Twitter too early because they will cache the old thumbnail / metadata. You should be able to update it with this tool:

Thanks for this.
I don’t know for sure which part of the chain the problem was happening as there are two moving targets:

1: Sketchfab takles an unkonown amount of time to create a thumbnail, and therre is no log/feedback
Maybe the thumbnail in the sketchfab dashboard is accurate and up to date - maybe not - no way of telling

2: Twitter takes an unknown amount of time to update it’s cache.- similar problems.

With neither service logged, it can be hard to know what’s up or which service to try and fix.

Thanks for your feedbackj.
