In this video I present how I captured and turned a real sculpture into a game ready asset using photogrammetry.
I also have some key updates regarding to my previous photogrammetry workflow about image preprocessing for photogrammetry reconstruction
In details I present:
- capture using Mavic 2 Pro Drone
- the photogrammetry reconstruction using Agisoft Metashape
- 3 different ways for retopology in ZBrush
- UVmapping the lowpoly model in the RizomUV
- and finally generating the texture in the Substance Painter with the smart material I made for this purpose
The offline version of this video which also includes the smart material I made and used in this video
as well as the high and low poly versions of the scanned sculpture for those who wanna give it a try
are available on my gumroad:

You are welcome mate, and thanks for watching :)
Great work. Thanks for sharing. Keep the videos coming, please.
Thanks a lot. I am doing my best trying
Brillant, pleased to discover your channel and admiring your skills in mesh editing.
Thanks and welcome to my channel then :) I hope you are going to enjoy it. Cheers!
your videos are a goldmine.. thanks!
Thank you Jonathan, I am really happy to hear that and will do my best to create even more :)
A new beautiful video 👍🏻👌🏻
Thank you
Great video Gregorz, thanks!
Thank you Ben, very appreciated :)
Thank you from New York USA . Great material Grzesiu , well done work. Good quality of cut in post. Not bad English. I'm in physics/energy /particles.

Thank you very much, doing my best but still learning and can clearly see there is still a lot ahead to learn :). Hopefully I can notice the progress and can see the quality difference between 1 year old video and just released one :) .. also in my english which is cool.. so its really cool to hear it isnt very bad :). Stay safe and have a great NY-ish day .... and big thanks for watching
Awesome video, very informative and i like the background music
Thank you Barny :)
tank for video, great job!
Thank you, appreciated
Very educational!
Thank you Ruben :)
amazing video man! i am flying a drone tomorrow and wanted to take a look at photogrammetry with it
You should! Imo drone gives really a lot opportunities you dont get with a standard camera. Good luck with scanning :D
spent the whole video trying to work out where the damn banging and popping noise was coming from until i realised it was on your video. damn 5.1 surround sound.
:D
nice flight 👍subed your channel from japan😊
Thank you and welcome :)
It would be cool to do a "Free programs challenge" like meshroom, blender etc :)
Yeah, why not. It's a great idea :). Cheers
and instant mesh for retopology :)
You're a real craftsman, sir.
I have a burning question though: If you had wanted to create an albedo map to preserve the original surface... how would you do that? It looks like the UV-map creation process destroys your ability to do so!
Thanks. I would bake the albedo map directly from the highpoly model. I would use a texture to transfer it. As long as UV doesnt overlap on the lowpoly you dont destroy/overwrite anything.
bro, if you have problems with the landing in your hand you can disable the sensors with the RC button on the right side (on the side), change the knob to the sport mode (S) position and you will no longer have a snesor reading, also be careful when trying , good video in any case
Thanks, the drone in sport mode is way more sensitive :), also have heard that sport mode turns off all sensors except the bottom one but I might be wrong.
Regarding to the hand landing.. I just keep practicing and its getting easier every try I make, have noticed that sensors doesnt see my hand when I grab the drone behind the gimbal what makes hand landing easier. But every time I can land on a the ground I prefer to land on the ground :). Cheers!
@@GrzegorzBaranArt in sport mode turn off all the sensors and of course it is a bit more aggressive but if you handle it with caution it is very useful for when you need to get down fast and the place is full of obstacles but you already know that a certain point down is released, you just also have to pilot feeling very safe I hope you stay well
@@GrzegorzBaranArt On the Mavic Mini, if you put your hand under it to catch it, it immediately pulls up, but if you just hold your hand there, and keep pulling down on the joystick, it will then go ahead and override its sensor, and land in your hand. Does the Mavic 2 Pro not behave that way?
@@dougdavis2523 I guess it does but you have to catch the drone, not just land on your hand since the drone looses stability with the rotors speed slowing down.. I mean that any wind blow can push the drone and when it happens you risk contact with propellers or crash.
Cześć Grzesiek ;)
Domniemam że jesteś Polakiem po imieniu i nazwisku.
Zaczynam przygodę z fotogrametrią.
Zrobiłem 120 zdjęć z rożnych kątów, wysokości i zbliżeń dookoła mojego samochodu.
Dron DJI Mavic 2.
Wgrałem fotki do Metashape w formacie DNG.
Gdy klikłem Align Photos jak w minucie 14:24 proces tworzenia modelu trwa już 2h i jest w niecałej połowie.
Dlaczego to trwa tak długo?
Mój sprzęt to:
Ryzen 5 2400G
16GB RAM
RX Vega11 2GB
SSD 480GB
Pozdrawiam ciepło ;)
czesc, sugeruje zmniejszyc wartosc z key point limit do 40.000 i tie point limit na 4.000. Wtedy image alignment powinin zajac okolo 3 minut :). Przy rekonstrukcji sugeruje uzyc depth map jak w moich nowszych materialach. Tryb depth map based zostal wprowadzony od versji 1.6. To video zostalo zrobione dla wersji sprzed 1.6. I w przyszlosci sugeruje bardziej zbite posty :) bo ciezko mi sie ten Twoj czyta prbujac odpowiedziec :D. Pozdrawiam
I use a simple cardboard as a lanidng pad. Once I tried to land in hand, and cut myself with propellers, drone drifted towrads me.
After 3 years I know my drone well enough to land safetly and take off from my hand. Even in tough windy conditions. Bear in mind that the wind is really strong and the drone struggles to maintain its position I dont fly as it makes no sense for me. Anway. when I do, I take off from hand always when the drone is keept away with the wind direction so the wind cant push it backward to myself. Of course it also faces away to me. From the same reason I use inversed rule while hand landing .. so I stay with the wind so the drone aproaches always against it. Next I hover at some distance and approach the drone by myself. I dont drain batteries to none so if something is worng, I simply correct the position and repeat the landing process. With some practice it seems to be really safe but even tho, if I have any flat surface available like a flat rock, bench, asphalt, I prefer to take off and land there. In most cases I take off from them as even if small, its quite easy to adjust drone position between the take off.. while if landing can be an issue I simply use hand. Personally I bleieve that hand take off is much harder and dangerous to the hand landing.
After I learnt how to hand take off and land, I dont cary any landing pods with myself. I used to use one for a while just to setup the gear in dirty, dusty environmet but now I use my backpack's cover for this purpose. So honestrly, I would suggest to get a bit more practice with proper drone landing and take offs and you will never ever need any landing pad solution.. and dont fly in conditions where drone isnt able to handle itself as you risk loosing the drone.
Some advice. Put the link for your youtube channel in your twitter profile and when you tweet that you have a new video put a link for it in the tweet.
Hey man, thanks for the tip. Appreciated :). I did it already, just no one really follows me on my twitter :)
Do create more.
WIll do my best. I already did since this one was released :). You are more then welcome to watch the other videos and I hope you find something useful there
You dont use Ground Station app ?
Hey, nah, never heard about it :), is it good? What it does?

Hi, Gregorz. Great job! Can you share mavic 2 pro barrel distortion preset for Photolab 2?
In Geometry tab I used 'Auto with Dx0 Optics Module' mode in distortion settings with the intensity set to 100%, I left 'Keep Aspect Ratio' option turned off. Also turned of the 'CROP' since it cuts part of the image. I also turned 'focusing distance' and 'horizon' off.
But these options are useful for single image based reconstruction where you need an image to look correct already. As I mentioned in the video, for photogrammetry any geometry fixes like barrel distortion are not recommended. Hope that helps :)
the music track is VERY distracting, had to mute the audio
I am sorry to hear it. Especially that I spent a lot of work to compose it, but thanks a lot for the feedback. You are not the first one who complains on it so to make my videos better might try to compose something calmer and less invasive in the future :). Cheers!
maybe he's learned since sept 2019 that some music soundtracks can devalue the viewing experiemce when trying to listen to the narration
@@GrzegorzBaranArt yes... i'm only here to offer an opinion to maybe make future videos more viewable to more people.

Witaj Grzegorz
mógłbyś stworzyć odcinek o tej samej tematyce po polsku
Mysle ze latwiej i szybciej by bylo po prostu stworzyc polska wersje jezykowa dla napisow.
@@GrzegorzBaranArt w takim razie bardzo proszę
@@GrzegorzBaranArt jeżeli można by było również do pozostały filmów o dronach to było by super
@@konradk2288 Stworzenie napisow to kilka dodatkowych dni pracy, natomiast znalazlem opcje w napisach z mozliwoscia autotlumaczenia na dowolny jezyk. Zgaduje ze to rozwiazuje problem i oszczedza mi pracy :). Pozdrawiam
@@GrzegorzBaranArt witaj już próbowałem zanim napisałem do ciebie, tłumaczenie automatyczne jest bardzo słabe szczególnie przy opisie funkcji programu
photoscan its sucks. Use RealityCapture next time. ;)
And, turn off collision detection to get closer to statue.
Hey Yegor, I would not agree. I am considering to record a video to compare RC, Metashape (not Photoscan anymore) and 3DZephyr...currently I am experimenting and researching a 3DZephyr .. and planning to release a video about it pretty soon. Each photogrammetry software has its own pros and cons. Metashape after version 1.6 has changed totally for better. Its more stable, doesnt need as much resources as it used to (32GB for extreme scenes) and finally with the depth map based reconstruction results are really good. So even if RC seems to be slightly better, the difference in reconstruction quality in my opinion is not worth the price you need to pay for it. Metashape is way more cheaper. It costs 179USD and when you get it.. you can keep it forever. You get all future updates to version 1.9 for free. I can tell you that I bought it 4 years ago for something around 150USD and didnt pay a single penny to get all updates. So no subscribtion.. no bs :). SO I would encourage you to givbe it a try as every software is in constant change and moves forward. Something what is mediocre today.. might be great tomorrow.
If I get the RC for 179USD and can keep it forever with future updates I would probably pick it :).. but now.. especially when pretty tough times are coming and you never know how long you can afford to pay tons of subscriptions.. having a piece of software you can simply use no matter what has really big value if you know what I mean.
Thanks for the tip with the collision detection. It saved my drone a few times already.. especially during windy weather. In my case it helps a lot since its super easy lose the sense of space when you scan from distance... but I totally agree that its a pain in the 'bottom part' and there are certain cases when I would do a better job with sensors turned off.. like probably this sculpture :)
Hope that makes sense :). Anyway, big thanks for watching my video and for your comment, very appreciated. Cheers! :D
@@GrzegorzBaranArt Hmmm. you are right, price its mater. I use Reality Capture from time to time by subscription.
About collision detection - im using one trick - going above sculpture, getting close as I need, and go down to the height i need. So I get closer then collision detection will let me and can go left right without problem. (On Mavic Air, I dont know how its will work on Mavic Pro)
this game-ready asset looks like it lost quite of lot of detail, way too much for my taste. Other than that good job, as always.
Thanks, depends on the game, size of the prop and its LODing system.. but yeah. .was trying to show the way.. not actually make a game asset.
