This tutorial is golden. Eventhough I did several objects with great success, shot in chunks, and now I feel really confident, I would just watch it for pleasure as I am doing right now, thanks again Alex!

Thank you, Alex, for another incredible tutorial. It was truly helpful because I spent the last two days trying to process an object capture with macro photos in two chunks and several loops, needing to use the mask. I wasn't succeeding with Reality Capture (a software I really like but in this case Metashape rocked for me). This tutorial saved me from having nothing processed to present at work! Now I have much more confidence in my workflow thanks to your excellent teaching skills. Gracias!

I just watched this again and not sure how I missed that Gradual Selection trick, but man is that helpful! I thought I would share a trick I discovered that you could do to fix misalignment after the merge if you're having trouble getting them scaled properly...I had this issue with the bottom of a shoe where it was noticeable bigger than the other. I actually ran the Optimize Camera's and then afterwards I re-aligned the photos for the merged chunk....not sure why that worked but it did, and it fixed the issue. I'm sure that simply making sure that both sets are taken from the same distance away for all the images ahead of time would probably prevent issues like this too begin with. I'm just theorizing. I bought a cheap laser measuring tool to help with that for next time.

This is a great tutorial, even though I'm working with UAV (drone) photogrammetry rather than 3D models, this is still probably the best explanation for aligning chunks that I've come across so far. Basically, I'm trying to align thermal images where the Ground Control targets are very difficult to see with an RGB ortho where the Ground Control is easy to see.

hi, thanks for this great video. I am following exactly same steps but my chunks are not at all aligning. What could be the issue. individual models in each chunk are visible, masks are also created but chunks are not aligning. Can you throw some light on this matter ? Would be really helpful.

Nice video! Simple questions: 1. Both turntable prints can be the same or you need to swap for bottom / top photos? 2. What camera are you using? I have two canons with several lenses, but Im worried with blur for fov. (I know, need better lighting to close lens). 3. Can I crop png for turntable and print in normal A4 printer?

This video has been truly informative for me, great content! However, I'm encountering the "not enough points to align" error during the align chunks stage. Does anyone have information about this? I'm looking forward to your assistance, thanks!

one like is not enough for you :) thanks bro

With what accuracy do you need to position the object from different angles (for example, from below and above)? I repeated your tutorial on my model: I ended up with the bottom model being photographed head left and the top head right, and the blocks didn't line up (the head merged with the tail). Thanks a lot!!!

I tried follow this tutorial but aligning didnt work. Bouth peaces overlaps each other. What else can be done in this situation?

Thank you. 👍

Thanks for this helpful video! I tried to print out the markers but they seem way over sized. If I were to print at 100% they are way too big. even 50% is too large based on the measurements you give.

Great video thanks, I'll try that pattern method. I did somehow get two chunks aligned though and the strange thing is when I merge the dense clouds only one of them is there....I'm not sure why. I've seen this happen on several occasions where they are aligned but when I merge them one is left out.

How are the equations when using turntable and fixed camera? Is there a resource that explains the equations for the fixed camera and the rotating object?

this is beautiful think you so much. have question about crystal objects i never was able to perform it. are there a solution ?

Watching this in nov 2023. I however, can't find the 'detect markers' option. Its not there, nor in the tools menu, Don't know how to fix it, can't find help on forums.

So the dense cloud is not relevant ? in this workflow is never needed to run the dense point cloud to keeping more resolution mesh ? thankss 🙌🙌🙌

Hello! Does this work on the standard version of Metashape, or only on the professional one? Thank you!

I usually do the masking inside RealityCapture Normal mode (resolution reduced 3times) -which is much faster and then I import all photos with mask into Agisoft and do the final part similarly as you do also this looks like super outdated Agi version, isnt it?

I really appreciate this video!! Most of the time I mask the photos first then run through the workflow. I have some object that metashape just don't like that process. This helped me out a ton. Thank you!!

Hello, professor. Do you use the same base - with the same markers - for the initial bottom and top photos? You have two bases with diferentes markers that we can print. Should we use the same for the alignment of the two chunks Thank you.

excellent video! but my chucnks don't align correctly :C, I put my object on a surface with marks, and when it aligns them, it overlaps each other, it doesn't put them like in your case. help
