[ENDED] Sketchfab 3D Scanning Challenge: Nature


Nature is everywhere and this month, in partnership with Agisoft Metashape, we challenge you to scan it. Anything natural qualifies, from the great outdoors to a humble houseplant.

Full rules and prize details can be found in the blog announcement:


Hi there.

Quick question, can I upload multiple entries into the Agisoft nature challenge?



Yes, multiple entries are fine :slight_smile:

Thanks so much for your response

Thomas Flynn wrote this under the announcement:

No you should not tweak or edit the 3D model beyond the reconstruction in Metashape (although you can decimate, bake normal + occlusion maps from inside Metashape if you want to)

Does this mean that the cleanup tools within Metashape are off limits too ? (such as: smooth mesh, fill holes, manual selection, discarding unwanted parts after selecting them, dense cloud filtering by confidence etc)
Or does this only apply to third party editing tools (such as ZBrush, Maya, etc) ?

You can use any of the tools that Metashape provides (smooth mesh, fill holes, etc.) but you cannot make use of external editing tools (Blender, ZBrush, Maya, etc.). :+1:

Perfect, thanks for the answer !

I was asking because I did some cleanup on my Spider Crab entry, but only within Metashape (which was quite a challenge :wink: ). Some details are still not as good as I hoped ; once the challenge is over I’ll probably try to improve the result using external software.


That looks great! We were both inspired by crabs. :slight_smile:

Hello! Can I rescan and submit a scene that has been uploaded 1 month ago, or it has to be a completely new scan?



Hi Vasilis! Your entry needs to be a new scene—whether that’s new photos and processing of a spot you’ve digitized before or an entirely new subject, it’s up to you. :slight_smile:

You cannot, however, just reupload something that you created prior to the start of the challenge. :upside_down_face:

Thank you for the clarification :slight_smile:

You all brought your skills and creativity to this challenge and it was SO DIFFICULT to pick winners. But pick we did!

And the winners are...

1st Place: Starfish & Sarcophyton - #AgisoftNatureChallenge by yuma.jp

“A wonderful way to raise awareness of the beauty of the coral reefs. A great scene to explore, and I really appreciate the effort of taking 300+ pictures at 5m under water!” - Bart (@bartv)

“Underwater scans always look like they’re from another world. The small blue starfish helped me to make the choice between yuma.jp’s submissions - it looks like a blue alien.” - Nikolai from Agisoft

“I spent a good bit of time looking at all the details in this one, it’s very intricate and fun to look at!” - Renafox (@kryik1023)

"The shapes and colors on this are great. The level of difficulty and use of annotations push this to the top for me. " - Abby (@abbyec)

“Very nice 3D scan underwater! The precision and the quality of the texture
is exceptional (especially underwater).”
- Geoffrey (@geoffreymarchal)

2nd Place: Red rose by Lassi Kaukonen

“The finest of the details is impressive. This 3D scan succeeded in capturing the thin surface from the leaves and petals!” - Geoffrey (@geoffreymarchal)

“Beautiful! The reconstruction is amazing especially because thin structures are always hard to reconstruct so well.” - Nikolai from Agisoft

“Great definition on the petals and leaves and a nice story to go with it :)” - Tom (@nebulousflynn)

3rd Place: Spider crab by Benoît Rogez

“Perfect scan of a crab from all sides despite non-rigid legs (special thanks for commentary with workflow description).” - Nikolai

"A very thorough and clean :crab: scan with high-quality textures. " - Tom (@nebulousflynn)

“This is a really good scan, and the fact that it’s a crab amuses me. It gets maximum crab points. I have to wonder how they got it to stay still” - Renafox (@kryik1023)


beautiful stuff! congrats to the winners and thanks for holding the competition!
