Frequently asked questions

Do I need to buy 3DF Zephyr to enter?

No. You can use 3DF Zephyr free, download the freely available 3DF Zephyr Lite trial or you can request a free trial for 3DF Zephyr. If you have doubts or questions, feel free to ask us :)

How do I register/submit entries?

During the contest, you will simply need to login using your 3Dflow account - submit your entries (the sketchfab link of your model) from this link after logging in with your 3Dflow account. If you have any question anytime, remember you can ask us directly over Discord,Forum or 3Dflow academy facebook group.

Do I need a Sketchfab paid account to submit?

No, you can use the free Sketchfab account. If you feel like your model would be at disadvantage due to the limitation, consider using a Sketchfab Plus account or let us know.

Can I use the sketchfab viewer features to better present my model?

Yes, feel free to put lights and annotations but most importantly, don't forget a good description! Judges love to read about your process!

Is this contest soccer themed?

No, it's just all in good fun :) there is no theme, so feel free to scan and submit your favourite subject!

So why did you call it 3Dflow World Cup, and why is there a 3Dflow logo kicking a football on this page?

For fun :) It all started when Italy did not qualify for the World Cup back in 2018 and we kept the tradition ever since, plus it is helpful to run the contest in groups to make it more interesting. That said, the contest is not soccer themed and you can reconstruct your favourite subject. It's just a fun way to drive the contest appearance.

My country is not available! Does this mean I can not play?

If you do not see your country, it means that somebody else was faster than you and grabbed it already. You can play: this contest is all in good fun, just pick one country you like :)

Wait, so what are the nations for?

They are just for fun - you do not need to be in the country you pick, nor you need to scan anything from that specific country. Countries are just a vanity fun stuff we use to split you in groups.

How do I adopt a country?

The selection of your country will be available at the moment of your first submission. Go make your 3D model before someone else gets your favourite country!

I am under 18 years old of age, can I enter?

Unfortunately no, as we will need your address in case you win, in order to ship you the prize. But, you can ask your parents to sign up and submit the scan at their name, if they are fine with it :)

Sweet! But what if I win something I already own, can I get something else if I win?

Unfortunately no, we want the contest to be the same for everyone. But if you win, you can choose to gift your prize to some other contestant if you wish!

3Dflow world cup contest rules

1. Sign up conditions and privacy

You must be 18 or older to be eligible for participation. You will be asked for your personal information (including email, name and surname) for the contest phase. In case you are chosen as a winner, you will be asked to share your personal information for the purpose of sending you the prize. Your information will be shared to third parties only for the purpose of shipping the prizes to you in case you are chosen as a winner.

2. Participation conditions

By signing up, you will be randomly matched with other contestants in a certain number of pools. Winner of the first rounds will advance to the final round where the winners will be picked.

You agree that by signing up and by purposely submitting invalid entries, 3Dflow may reject your application to future contests and/or disqualify you from the contest.

You may submit more than one entry for each phase in which you are participating, according to additional rules that may be announced via email.

You agree that your submission (included, but not limited to the final model, the photos, or other components) may be used by 3Dflow for marketing purposes.

3. Submission
  • Submissions of entries must be made with 3DF Zephyr (any version) within the time limit that will be announced for every round
  • Post processing in third party software is limited only to leverage the specific features of 3DF Zephyr. This means you won't be able to decimate, clean or alter the resulting geometry in third party software, however, you can use third party software for UV-mapping or to assemble a model using the normal map and displacement maps generated by Zephyr. Of course all in-zephyr tools (cleaning, decimation, etc) can be used as much as you need.
  • Similarly, post processing the texture is not allowed (e.g. using photoshop). You can change the UV map topology (using e.g. blender, then use the Zephyr feature to regenerate the texture with custom UVs) but you cannot change the texture in third party software.
  • Use of Laser Scanners is allowed - judges will ensure a fair evaluation keeping in mind not everyone has access to such devices.
  • Submissions of entries must be made according to specific rules that may be announced for every round
  • Submissions of entries must be made with new, original images that you have taken yourself in the time frame from 01.07.21 and processed with 3DF Zephyr 6.0 - yes, you can submit models you have published on sketchfab before the 3Dflow world cup announcement - make sure to update the sketchfabs tag though!
  • Submissions of entries must be made of 3D models that have not been submitted to any other contests
  • Submissions of entries must be made by uploading them to Sketchfab using the tag 3dflowcup21 and submitting the sketchfab URL to https://worldcup.3dflow.net by logging with a valid 3Dflow account.

3.1 Submissions - Round rules
  • Round 1 - You can reconstruct anything you like (no theme). Multiple submissions are allowed.
  • Finals - You can reconstruct anything you like (no theme). Multiple submissions are allowed.

4. Advancing conditions

Your entry will be judged by the appointed judges listed in this website. The entries will be judged according to quality and originality. The judges' decision is final.

5. Prizes

If by chance the prize is no longer available at the end of the contest, 3Dflow SRL reserves the right to change the prize to a similar object of the same type and price range. If this happens you will also have a say in the replacement chosen.

The price will be shipped to the address that you will specify and that must match your name. No PO-boxes will be accepted as destination addresses.

Winners will be contacted privately at their registration email address. Winners have 30 days to claim their prize by replying to that email.
