Hi! Thank you! The dense cloud is a much more refined and detailed version of the sparse cloud which means that your final mesh will be more accurate and detailed with a higher poly count. Its also the best way to create DEM's (covered in another video) which are a key part of our process with rock art. There are also a number of tools that can only be used on dense clouds, like dense cloud confidence (which makes it super easy to remove low accuracy points). These are great, especially when you are making a full 3d model rather than just a surface. They also give you a good impression of the quality of your model and where improvements can be made. I just ran a small test to compare the poly counts of the final models - based off a dense cloud the poly count of the high res model was 5052321 polys, while based off the sparse cloud the poly count was 90000. It may be that you would want a low poly model to start with, but there are also better ways of doing this later on (e.g. decimate model -> create normal map so that you get the details of the higher poly model on the lower poly model). Hope this helps, if you have any more questions please feel free to ask!
The .jpg file is likely the texture for the .obj file which should also export at the same time. You should also have a .mtl file which links the two together. Try creating a new empty folder and then exporting to there to check that everything gets exported correctly.
Thanks for making this! Very clear and straightforward.
Clear and simple, even I could understand it. Thank you.
Very useful and straight to the point! Thank you!
thank you!1 this video was super helpful!!
This is the best view of the Metashape Pro workflow that I have seen. Thank you.
Where can I find the other videos you referenced?
Thanks, glad you enjoyed it! These videos were originally produced as part of a course and as such not all are publicly available yet, unfortunately.
this was super ! thank you! What is the point of building the dence point cloud and not just go directly to mesh ?

@@rockartarchivesguhistorisk7591 This helps A LOT!!! Thank you so much for the answer !
Thank you for the great video. Why does the model doesn't export as .obj and instead it does as a jpg file?
The .jpg file is likely the texture for the .obj file which should also export at the same time. You should also have a .mtl file which links the two together. Try creating a new empty folder and then exporting to there to check that everything gets exported correctly.
