In this video I present full photogrammetry workflow for PBR materials with the drone used to capture the ground surface.
In details I present:
- surface capture with the Mavic 2 Pro drone
- RAW image tweaking and micro shadow removal in Photolab3
- photogrammetry reconstruction in Metashape with the texture used to cary albedo information
- I create and align lowpoly model in ZBrush
- texture baking with the Substance Designer baker
- AI based seam removal with the Unity ArtEngine
- additional delighting with the Substance Designer
For those interested to dig a bit deeper into photogrammetry details feel free to grab my ebook:

Dzieki za dzielenie sie wiedza, wszystko testuje i działa :) pozdro!
Milo mi to slyszec :). Poz
Dlaczego dopiero tutaj trafiłem? Nie widziałem bardziej skondensowanej klarownie przedstawionej i przede wszystkim darmowej wiedzy - a ta jest bezcenna. Dziękuję bardzo 🙏
Bo to jest juz prawie sam koniec internetu ;). Dzieki wielkie za mile slowa i za komentarz. Pozdr.

Cheers!
It was a very enjoyable lesson. Thank you.
Really glad to hear that, Cheers!
Always great info in your videos. Thanks!
My pleasure! Cheers :)
Awesome as always. I love how you manage workflow with batchs in metashape. Thanks for sharing.
Thanks a lot. Usually I dont include image alignment part of the pocess to the batch processing as its too risky and if goes wrong I waste a lot of time on useless reconstruction which has to be repeated. Also after image alignment you have an option to limit the reconstruction area by changing the bounding box coverage and in result speed up the reconstruction process. Just saying :).
Cheers!
Fantastic tutorial!! Thank you for putting this together.
You're very welcome Michael! Big thanks for watching :), I am really happy you like it.
Thank you so much! That's great! Please carry on!
Thanks man :), will do my best
Dzięki za kolejny świetny materiał 😀

Great tutorials. I'm getting way better results now thanks to you!
Thanks, it means a lot :)
Excellent, thank you!
You are welcome :)
You are the best! Thankssss!!
Cheers! Appreciated :)
Hi Grzegorz today I bought your Photogrammetry Enviroment PBR Material Creator Guide which look deep and amazing. The same way I download all your videos for fully and detailed studie of your technique that I think is precise and comprehensive to put in practice. I m so inspire for your work and my goal is reach your level of expertise. Once I get good results I wanna share with you all my knowledge in this process. Keep doing this amazing job.
Thank you veeeery much Carlos and thanks for the support. I am super happy to hear that. Wish you good luck with the photogrammetry capture. It just a matter of time when you get great results if you only just wont give up as mostly its the matter of practice and awarness of tools :) you can use. Just keep going. Looking forward to see your results
Thank you. very cool.
Cheers! :)
Amazing workflow man. Really fun to watch the whole process
Thanks Sai, appreciated :)
You have best tutorial
Thank you very much
Don't know how i missed this one!
:D I am happy that you have found it finally and it was worth to watch, cheers!
cows are so cute !! great tuto
Thanks Astrid, and big thanks for watching :)
Great job and thank’s a lot for sharing your process wich is really handy
Thank you Laurent, very appreciated. I hope you found something for yourself in here :)
@@GrzegorzBaranArt Yes, and it's thanks to you ;)
Great videos, thank you for sharing such useful information) I will take your advice and knowledge.
Thank you, I am super happy to hear that :)
Excellent video, nice and concise. I really enjoyed seeing the dangerous animals ;)
Thank you Barny :D
great workflow. thanks much. we have been using open drone map for georeference tiffs
Thanks, oh.. an open source one :) .. sounds interesting. Currently I am playing with 3DZephyr for reconstruction, I am planning to cover it in a future videos.
Talks about dangerous animals and points to cows **lol** Another great video Grzegorz! Thanks for showing us your workflow, I've learned a lot! Btw. I've had problems with seagulls before too. Especially in breeding season they're super aggressive. I'm impressed that you actually managed to dodge the seagull. That's not easy as they're absolutely pros in flying and have it literally in their genes and they do it since they were born. More often than not, you cannot outfly a drone from a seagull. Glad your Mavic made it home safely!
They are way bigger to dogs so I was sure they are way more dangerous ;).
Regarding the seagull.. the first time I managed to dodge the seagull was when I realised it dives to the drone on full speed. I read theat the best way to break the attack is to change the distance so I started climbing. This way I broke the attack and seagull had to turn and take another approach. It gave me some time to decrease the altitute and head dowards me but at the same time I have noticed that seagull read this as and attepmt to escape and it made her iven more agressive. So there was another attack.. you can see her shadow with this one.. it was the moment I was sure I wont make it.. but I moved to the side and it was another thing seagull didnt expect.. so had to move again.. the last one was when the drone was hovering next to myself.. it was the moment went into really crazy mode and I jumped next to the drone to cover it.. and it was when the seagull realised that its not a fight with the drone anymore but with human so it made another circle.. this is when I recorded her.. and flew away.
Before the segull attacked she screamed a lot.. now when I just hear any seagull I move the drone towards myself and keep it close.
The funny thing was that it was the first day after my 'DJI CARE' or whatever it is called.. insurance was over. But at the end it just turned into a bit more experience I can share and another hopefully fun to watch video :).
Big thanks for kind words and for watching :)
@@GrzegorzBaranArt hahaha wow what a story! :D That day was for sure not just shoot&chill :D Good idea with changing the direction and fly the drone towards you! regarding cows: I am swiss, we probably have more cows than people ^^Cows are pretty easy dudes, as long as there is no calf in the herd. If there is one, you better stay away of the heard, but I think that's pretty obvious. Another thing is, that cows have not such a good eyesight as human. If you approach them, be sure to move slowly and in their field of view. They need about 10 times longer to recognise an object as we human. Keep that in mind and have a good portion of common sense, and you won't have problems with cows. ^^

Fajny film. Za diabła nie rozumiem tematu ale bardzo mi się podoba wykorzystanie drona. Kupiłem Air 2 S i chciałbym spróbować zrobienia wycinku terenu w 3D. Trochę mnie Twój film zainspirował. Pozdrawiam
Dziekowac :)
damn birds :D
:D
Really enjoy your videos, helped me a lot. Can I make a suggestion for a sort of "troubleshooting" video? So a collection of problems you have ran into over time and ways to solve them.
Thanks a lot, sounds like a good idea. Will add it to my todo list :)
Dziękować 👍 bardzo pomocne materiały wrzucasz (wszystkie już pobrane na dysk 😎)
Powoli kompletuję sprzęt do fotogrametrii, przede mną kupno porządnego obiektywu. Stąd moje pytanko: jaki polecasz do skanowania małych i średnich obiektów? 18mm? 50 mm?
Cala przyjemnosc po mojej stronie. Z tych dwoch polecam zdecydowanie 50mm. Imo idealne byloby 35mm. Pwowodzenia w skanowaniu :)
Thanks for the video. I recall when alchemists was announced the ai delighter was applauded, is it not as good as you hoped?
It wasnt very good when was released but it was improved. The new update brings totally new delighting quality and so far works great.. before delighting was quite useless. I am planning to create a new video to cover it since Alchemist grows really fast and is in constant change.. currently I am testing it and got surprisingly good results, unfortunatelly the tool still lacks of any control.
Jakich technologi uzyblys, gdybyś miał przenieść całe miasto do rzeczywistości 3d? czy użyłbyś samego skanowania? czy może posłużył byś się już stworzonymi mapami żeby je poprawić a może wygenerowałbys obiekty w Cesium?
Odpowiedzialem na Artstation :) ale szczerze, zaczalbym od czegos mniejszego zeby zdefiniowac sobie workflow, skompletowac ekwipunek itp i oszczedzic niepotrzebnej pracy pozniej
Beautiful nature. Where are you from?
Thanks. The capture was taken from here:

Grzegorz Baran wow. I thought that was Eastern Europe) Wonderful!
What if my game is not in Unity, but in some other engine? Can I still buy and use the Unity/Artomatix ArtEngine? Thank you :)
Hey, of course you can. ArtEngine is a separate, standalone app, but since the company 'Artomatix' which made it was acquired by the Unity a while ago, it is being sold by the Unity now. So to purchase it you will need probably to set the unity account to manage ArtEngine license from there and thats it. But to get more details you would need to contact unity sale dept as I dont sell it :). And yes, you can use it however you want and results achieved with the app are not linked any way to any game engine or rendering system.. similar to Substance products.. when you generate textures you can use them however you want to. Hope that helps
@@GrzegorzBaranArt Awesome Thank you :)
What's the pricing like for an Individual with ArtEngine? There's no information on their website about this.
They were acquired by the Unity recently so I guess you should start looking there. Have no idea about their pricing model tho but it was pretty expensive. I strongly believe that with the Unity onboard it should be affordable for Indie users soon :)
You can request a trial version if you use this link:
create.unity3d.com/artengine-demo
regarding the pricing, when you do their sale representatives should contact you to discuss the pricing and other details :D
Hope that helps, Cheers!
Like for saved dronie
:D
Hi Grzegorz I hope you are very well in this quarentine period. I m write to you because i ve a problem when I try to build the mesh of a surface using Height Field 2.5D parameter. The grass height is to high when the Building Mesh process is done. So I wandering if this height filed parameters is tweakable to get better result. I don't know if i doing something wrong.
PD: I follow your PBR Material guide which is awesome and how you say the constant factor is a important matter when I made my composition, but I would try to push my limits a little more further into this so to see what going on I let you a picture. Finally, do you think it is possible to mix grass and ground has a single surface using Height Field 2.5D parameter?

I wouldnt use High Field reconstruction mode anymore since the new reconstruction mode - depth maps based Arbitrary mode - introduced in 1.6.0 version of Metashape gives you full 3D reconstruction in a way more efficient way. And it doesnt need infinite resources anymore. Especially the grass is the type of surface which has to be reconstructed in full 3D, otherwise you are gonna get glitches if the baking plane angle doesnt match in 100%.
@@GrzegorzBaranArt Thanks for your fast reply. I appreciate so much. Yes, I agree with you the Arbitrary mode make a better 3D reconstruction in difficult surface. At this time I can't find a solution to reach 100% angle alignment in my low poly 3DPlane uv-mapped at Substance Disegner to bake it. I am attaching some images so you can see how the baking of the textures is. I have been struggle to this since 3 days I m simple stuck here.

I saw a couple of time your videos and look like simple but i don't know what could be happening. I try everything, since move the baker parameters in Substance and different angle rotation in Zbrush. Nothing.
I must be missing something in the uv re-construction in Zbrush. What can i do to correctly align the low poly model in Zbrush?
