It doesn’t seem not allowed to me, anyway, let’s see what judges will say.
I agree with Jaakko but we will have to wait for a Pix4D employee to weigh in on the “edit” process. The challenge is in taking the pictures and setting up the Cloud to process…not in how many hours a person manually edits a point cloud.
I also think doing point cloud cleanup shows flaws in the project but I certainly don’t do every type of project out there either 
Hi there,
Is it normal that people with a not upgraded license can not submit their project to this first Pix4D challenge?
Anyway I had so much fun doing this 3D model of my favorite objects: see below a screenshot of my Wine & Cheese project :-)
Best and bon appétit.
Emile.
PS: I used the edit function in the Ray cloud to clean up a bit the bottle of wine. Made with 125 images taken with an Olympus OMD-5 and no GPS tag of course.

Hi,
Awesome models so far! It’s great to see so much enthusiasm.
Some clarifications:
- rule number 2 states that the processing should be done on the cloud. The point cloud edition does not get saved when this is done, we can do this for a next challenge. So it is not forbidden, but in this case they will be helpful only for the screenshot. The models will be judged from the cloud link you shared in this post. Please stay courteous between participants, thanks
- @Emile: cool model! Yes, you will need an up to date license in order to upload the project to the cloud interface for processing and sharing. You can update this in the profile page on your cloud by clicking “extend now” if you have an existing license. Otherwise, the Sales team might be able to help with a new license or a 1 day trial to upload the project, that’s something to check with them
@Pierangelo
My point being that you can edit point cloud on desktop, generate 3D mesh and upload just the .obj + .mtl and .jpg files to cloud. This way you can circumvent cloud processing which meas you can clean the model by doing a lot of point cloud editing
If you upload files right after step 1 only then the cloud takes takes the drivers seat on the whole process and this way the model has almost always more or less “flaws”
If you check out these models and click on the “map” on the left. It shows you the orthomosaic if the processing is done on the cloud. But if you have just uploaded the 3D-model files it says “Map is not available” because no photos were uploaded.
@Jaakko
Yes, agreed, I think we understood each other. We will make sure that it was processed on the cloud for evaluating the projects. As Adam said in this challenge the image acquisition is an important part to reduce the “flaws” or said otherwise, to reduce the noise and the necessity to edit the point cloud. For those who did not process on the Cloud, please make sure to re-upload the model
Hope it’s clearer now, if there are questions feel free to comment.
Out of competition - I just could not resist joining the challenge
model: https://cloud.pix4d.com/pro/project/207628/mesh?shareToken=f81a6f533b4448929ae8a16ecf772e25
image acquisition: 1:22 min of mobile video (Samsung Galaxy A3 (2017)), resolution: 1920x1080 , # of extracted image frames: 249
(I cheated for the screenshot 
: 5 min of cleaning in the Desktop)

Hi Guys,
Out of competition too , but I wanted to share with you a short video I have made 3 years ago during my PhD to explain people what PiXD could do. And it is fitting perfectly this challenge So here is My lemon tree.
Best. Emile
@Pierangelo: Thanks for your answer. Unfortunately, I have no time to update my license right now…

I have updated my model - cleaned the mesh

Some super projects submitted!
The judges are going to have a tough time.
Pierangelo:
Thanks for issuing this challenge
I regret that I shan’t be submitting a small object for the challenge.
Work has simply caught up with me and I’m leaving for the coast to attend another meeting,
I did model a small painted reed frog. A live one. No, not from the aeroplane. I just don’t have the time to clean up the point cloud or to upload the project. Have to leave now.
The intervening work is quite interesting. People who study age and growth of elephant and their population dynamics want me to model the morphometrics (shoulder height, tusk length) of some hundreds of wild elephant.
I’ll start flying trials in two weeks. In the meantime I put some archive pics of elephant I happen to have through initial and densification to see what it will look like. The results are quite good.
The challenge will be to capture about 20 or more oblique images while flying an arc around the subject without the subject moving.
Kind regards
Wynand

I just re-uploaded the project and processed it on the cloud, and it look horrible and unusable. Please check it here:
https://community.pix4d.com/t/4208–Pix4Dchallenge-1-3D-modeling-a-small-object
Pls compare it to the desktop processed one in the page 1 of the thread, this is why I didn’t uploaded the original model before work on it manually on the desktop app.
Regards

@Oblivion Aerial, thank you for updating the link and sharing your project as processed automatically on the cloud, now we can consider it as valid submission, according to the rules set for this challenge.
Hi Veronica, you’re welcome, but please, if you’re going to judge our submission looking at the model cloud processed, please consider us as non participating to the challenge. This is not the quality we’re used to provide.
Oblivion Aerial, changing the picture setup and Pix4D options should cleanup the mesh 90% or more without any point cloud edits. That is the fun part of this challenge by using the full Cloud processing workflow. Once the techniques are learned then it will really make the overall workflow quicker and easier than manual edits.
And your model is not horrible by any means…Pix4D is not great at any meshing plus I found the desktop version with my hardware to be better than the cloud version on Pix4D’s hardware. We are all in the same boat on this competition that the rules limit us from our “best work”.
Hi,
Here is my entry for the challenge:
https://cloud.pix4d.com/pro/project/208332/map?shareToken=0507329b079645278be6cd9ef9fb213d
It’s my first one on the cloud, a bit disappointed by the fact you can not adjust the process parameters, or edit the cloud, but the result is nice!
The difficulty with that model was to be closed enough to the elephants, and have the baby and his mother on the same model, hours and hours of patience and tracking 
Nice projects here, i saw the challenge a bit late to make something really worked, see you next time!!

Hey Everyone,
I decided to create a 3D model of one of our older drones… the DJI Phantom 3 Pro. This model was created by initially capturing approximately 250 photos of the drone from all different angles. As processing all of the images ended up creating a very blurry model, I decided to narrow the photo amount to approximately 75, in which a cleaner model was generated. The imagery was captured by a DJI Osmo Plus (12 megapixel) camera. The project was uploaded and fully processed in the cloud.
We use drones to capture all of our aerial photography, and generate high resolution orthophotgraphy and 3D models in order for surveying and engineering purposes. Working with small objects is definitely a challenge and was very neat to do. You may notice there are many rubber bands placed on the copter, as the solid, smooth white texture created waves when there was nothing to define it. The rubber bands add ridges and breaks within the white surface and allows Pix4D to create a smoother 3D texture, when compared to the model without rubber bands.

Pretty cool modeling of elephants…but I doubt they fit within the 30cm size requirement
And you can change the settings in the Desktop version before uploading to the cloud.
