Fix Holes in Photogrammetry With Blender: How To Repair Bad Photo-Scans

[@MRZEdits]

this is the best video I ever saw about clean retopology

[@AdamCServices]

You sound like the guy in the background when watching winnie the pooh haha legend

[@joshuadesigfinity]

Hi i find something that can help sometimes and is use the key "H" to hide mesh in edit mode to only work in the sectioni that you want, also you can show all again using "alt+h"

[@blenderbones]

Absolutely. Not only does this method make it easier to see what you are working on, but it also frees up a little ram and makes for a smoother experience. Thanks for sharing.

[@jeremytodd1]

This is probably the best tutorial on ANY topic that I've ever seen on youtube. Thank you!

[@hunterwenglikowski8335]

Tip to find where in the mesh a UV section relates to: There's a button called "UV Sync Selection" in the top left of the UV editor (It's two diagonal arrows going in opposite directions next to the select mode) that keeps UV and edit mode mesh selection in sync so you can click faces in your UV and it will light up on the mesh.

[@blenderbones]

I didn't know that. I have learn't something new. Many thanks.

[@Gounesh]

Extremely on point tutorial! Clear and not full of bs!

[@TNrealestatephoto]

Subscribed!! Love this video - 13 Years ago I was pretty good with MAYA but now that I'm into photogrammetry (landscape, and automobiles mostly) I'm having to relearn a lot of basics . . . this is exactly what I needed!! Thanks so much.

[@blenderbones]

Awesome! Thank you!

[@adeadegoke4925]

Thanks so much for this tutorial. What I appreciate about this tutorial is how you say exactly what you are doing. Thank you

[@blenderbones]

You are welcome. I hope you go on to create plenty of great photogrammetry models.

[@cypher82666]

One of the most usefull tutorial I've ever seen

[@blenderbones]

Wow, thanks!

[@parsec3d]

If you sculpt on a hi res version with dynamic topology on and using just snake hook and simplify you can fill holes in no time.

[@kirkr]

Great tutorial, very clear and helpful.

[@jasonmillington]

Thank you!!! Just started with Photogrammetry, this has answered so much, feel a really useful tutorial, for someone who is just stepping from beyond the basics on a few area's of 3d modelling!

[@blenderbones]

Glad it was helpful!

[@HammerdownProtocol]

Fantastic tutorial. I'm an industry pro of many years (mainly concept art and matte painting), and for some reason, retopology has held a special fear for me. I can see me working this easily into the Blender part of the pipeline. Bravo, sirrah. Subscribed

[@blenderbones]

Thanks for this. You have made my day with this comment!

[@АндрейЗнак-и1б]

Thank you very much. Good job!

[@cukiris_]

Thank you so much! BTW, amazing job with this model!

[@Wazgrel]

Fantastic tutorial man!! Thank you!

[@ahmedouardani2370]

Great video !

[@ismailgulsen4755]

hi, great tut. you can try quadfill to dill the holes with quads

[@blenderbones]

Quad fill does work well most of the time. But not always, especially when the geometry is jagged and inward facing. It's good to know how to split up geometry manually. Please don't forget to like and share. Thanks for the tip! If you have any suggestions for the next video, please feel free to let me know.

[@amitanshu]

Very Helpful...Thanks for this video...Keep it Up...

Very useful and thank you so much

[@fitzladams]

Excellent Video. Thank you.

[@cinemyscope6630]

My I ask about your workflow if Instant meshes looks fine at solve but then shatters the mesh into many pieces upon clicking extract? Thank you for your excellent tutorial!

[@robertomachado7581]

Great tutorial; thanks! Model purchased on CGTrader!

[@blenderbones]

Many thanks. :)

[@acsomiT]

Very good tutorial! 🙏

[@keterbinah3091]

good Tut , im always learning , forgetting & re learning

[@blenderbones]

You gotta keep on using it! :)

[@bagadavid9477]

Actually this is sth I need. Thank you soo much

[@GrummanCheetahPilot]

Great help for me as a beginner. Is there a way to mirror one half of a capture to create a whole image, I.e. I scanned my airplane using Polycam…..I captured the left side pretty well with few minor holes, but the right side of plane looks like it’s stretched across multiple dimensions. If I could mirror left side then I think I’d have a complete model to touch up and work with. FYI…I’m a compete newb….and know little to nothing about blender. Ty

[@blenderbones]

I like the fact you have an airplane! I would place a large cube over the rough half, and perform a boolean on it to cut it out cleanly. Then, making sure that the reference point is in the middle, add a mirror modifier. Let me know how you get on.

[@GrummanCheetahPilot]

@@blenderbones thanks I tried the Boolean trick and it worked great.

[@blenderbones]

Excellent! If you want the perfect model, try retopologizing it over the existing model, and then bake the textures from the old to the new. It will take a long time, but you will have the perfect model.@@GrummanCheetahPilot

[@Mr3buna]

If u are using any photogrammetry software, instead of texture painting you can also import fixed mesh back to that software and try texture reprojection or texture whole model again.

[@blenderbones]

I like the sound of that. I will try it out. Thanks for the tip.

[@jjfoerch]

great tutorial!

[@AnthonyLamb]

Really good tutorial, thank you.

[@johngrayson1441]

Hey Blender Bones! Awesome tutorial, also your voice is epic. I have a quick texturing question. When I fill the holes with the "f" key, the texture has a stretched look to it. I didn't think much of it since I was going to use the stamp tool on top anyway. However, after baking when I got to the stamp tool step, any mark I made on the hole, was then painted many other places on the model. How can I use the stamp tool and have it localized to the part of the mesh I'm working on?

[@blenderbones]

Sorry for the late response. I am glad you like my voice. I am not sure about it myself. I sound like a middle-class Bill Oddie - lol! The holes - you will need to unwrap any new holes. It is better to fill the holes before baking the textures. Regarding the stamp tool, I have to be totally honest, I am not sure. Perhaps another Blender person in the comments could shed some light on this?

[@msharp624]

Is David Attenborough making tutorials now?

[@blenderbones]

Haha! I see what you mean, now you come to mention it.

[@dreamweavecreations]

Thank you so much for this!

Pls make a video how to fix roof after photogrammetry export? My roof is very wavey and I want to FLAT it out. thnx

[@FranciscoGonzalez-wy4bl]

Muchas gracias!

[@kealinit7052]

I was doing the image bake yesterday and it was working, there were just some errors with the uv map. so i went into zbrush and re-UVed and re imported into blender. but now it just give me a black image texture. any advice?

[@kealinit7052]

i literaly spent a whole day trying to fix it. its the metalic its gotta be at 0.

[@JamesMiddletonDesign]

@@kealinit7052 (I am the author of this video...just signed into a different account.) I am glad you got it working. You beat me to it. Thanks for watching the video and please share!

[@cinemyscope6630]

Excellent!

[@Promeneur]

Great ! Thanks a lot...

[@blenderbones]

Glad you liked it!

[@GaWoP]

I'm running into the unfortunate issue where when I bake following all of the steps shown here, I get a blank checkered background in the image editor. I have triple checked all of my settings relative to the tutorial. I have ensured that I have High Res selected first, followed by Low Res, and I've ensured I have "Diffuse" deleted in the Shader node editor. No idea what's going on. Any thoughts? Editing to clarify I am on "Version 4.1.0 (4.1.0 2024-03-26)".

[@GaWoP]

I think I finally tracked it down after a lot of headache... I changed my view Render samples to 8, not my actual render samples to 8.While my "bake" was completing, my only theory is that it was so unreasonably large that it didn't bake properly.

[@blenderbones]

So sorry I missed this comment. I'm glad you got it sorted.

[@fernandobastiascroudo7084]

Hi, thanks for this tutorial, i need to ask you something, im having some problems.. After connecting the color node to the base color, certain parts of my model do not match, that is, the color that is applied in some areas does not correspond to those, it is as if it were smeared, it duplicated some parts in a certain way. What could be wrong?

[@fernandobastiascroudo7084]

I decided to make my 3d model again, but now, i made it with meshroom (previously using metashape). With that model i started the tutorial again, and now i dont have the same problem. I just needed some time and to re do some steps from the beginning. Thanks againg for this!

[@adibahzulfakar6579]

Hi may i know how to export .obj file from blender to context capture master (bentley)? I've tried but it doesn't seem to work. It came out blank on bentley. Thanks!

[@blenderbones]

Take a careful look at the settings on the export dialogue box. It could be that you have "Selected only" checked.

[@jimmycote808]

i need to know if i want to 3d print this and i want all the detail can i convert low resolution to high resolution or it's not possible?

[@blenderbones]

That's a good question. I am not too sure. You might want to investigate the Displacement Modifier. You might be able to do something with that. Anyone else got any thoughts?

[@form724]

Thank you very much

where can i find instant meshes

Why do you all always instant meshes but never post a link to it?

[@dirkdonges1349]

Hi, I sorry but several times I treid to stop and to find an detail WHAT you are clicking and WHY it does not look the same on my PC. For me, being a beginner, you talk MUCH (!!) to fast and you dont show WHERE to click. Maybe I am not the only one, not knowing "out of x-ray mode" ... Sorry... If this should be a tutorial, one should be able to follow, is my opinion. 😊

[@blenderbones]

Thanks for the feedback. The problem is, if I talk slowly, people complain. If I describe everything I am doing, I talk too much. It is a tricky balance to make. I know that these tutorials will not suit everyone. However, you can slow down or speed up KZbin videos. This has helped me a lot in the past get the best pace for my learning.

[@JaxiPaxified]

Having that addon that shows keypresses is very helpful, people can always look at what you pressed if they are in doubt.

[@googleyoutubechannel8554]

It's depressing that in 2023 3d software is still so primitive that so much manual cleanup is required.

[@Galllam01]

Thats just how it is when you try to convert anything in real life into digital world

[@CorruptedKarma]

the fact that we can turn some pictures into 3d models is already insane

[@googleyoutubechannel8554]

​@@Galllam01 "Thats just how it is" - you've been conditioned by lazy software to think this way, there's no reason why modern ML techniques and even regular advanced hand-coded algorithms wouldn't be able to do 99% of the work cleaning up meshes.

[@primalbeans]

Scan software I'd extremely complex. Vertices are aligned on the fly based on pattern tracking. The fact that a computer can record this data and align it is pretty impressive and takes a lot of compute power. Not to mention it relys on human control. (Hardly perfect.)

[@aperson381]

Blender is free dude. Its already industry standard and everybody can use it. Your perspective is what is depressing if we are just being honest. Perspective is everything my brotha, everything is pretty cool‼️🕺

[@makersprototype5115]

So you not use blender for solving the issue like said in the title of you vid. thumb down.

[@blenderbones]

Not sure what you mean? I do use Blender to solve this issue.

[@jakezuccaro5088]

No offense but your voice was a jumpscare

[@blenderbones]

Boo!
