Bug Reports / UDIM issue with 1010 texture
« on: September 26, 2022, 12:55:24 AM »
Does anyone else happen to work with big Metashape UDIM mesh models in Substance Painter? I’m hitting a problem when I have 10 or more texture files.  The 10th is missing its associated UV tiles when I open in Substance and is therefore projected wrongly. All other texture files, >10 and <10 are fine, but the 1010 is screwed.  I’m not sure which end is causing the problem.  If I regenerate textures in Agisoft at lower resolution to keep tiles under 10 then the problem goes away, but I need more resolution. 

Can anyone assist?

General / Re: 100m Geoid Error - OSGB36 + ODN Height (EPSG::7405)
« on: January 21, 2022, 10:59:05 PM »
Alexey - I discovered this same error after a big sparse cloud process on 12,000 images. I have successfully reopened in 1.7.6 and markers are now correctly positioned. However, the altitude data is still offset against the cameras. Am I safe to leave it as it is, or should I apply an offset to the altitudes? I'm not sure it's exactly 100m either, probably a bit less, and I'm not even sure if it's consistent across all the images. Quite a bug!

Bug Reports / Re: Can not display already generated part of project

UPDATE - if I export/import the point cloud into a new project then I can see it fine. However, I can't process the further deliverables - I get a 'null model' error.

I've just had this exact problem and it's really screwed up a project I'm working on.
3 chunks, and after processing the dense cloud in the 3rd chunk ALL the layers in EVERY chunk are not visible. The only components I can see in any chunks are camera positions and thumbnails. How do I get everything back?

Fantastic- that's very reassuring and has added to my knowledge - thank you!

(p.s. if you also replied to my Facebook post I'm further grateful)

General / RedEdge dark orthomosaics
« on: July 02, 2020, 09:49:09 PM »
I've seen others reporting this, but no conclusive answers...

The RGB orthomosaics produced by my Micasense RedEdge surveys are generally very dark. I use reflectance panels for calibration with normalisation checked. I then produce the RGB by setting the raster calculator as below.

However the entire dynamic range of the RGB bands seems to be in the 0-0.1 range on the histogram, hence the dark images I guess. Is this normal or is something going wrong? It is recoverable if necessary, but seems odd.

General / MacOS/Windows project compatability
« on: December 12, 2019, 06:47:21 PM »
Is it feasible to use projects interchangeably on Mac and PC versions of Metashape? I have some models I want to process on AWS but then manipulate locally on Mac OS

This I don't know. But I'll get it and send it over. Thanks Alexey

General / Projection files from Trimble GPS units
« on: September 04, 2019, 10:22:16 PM »
I'm working on a site where there is a local grid in operation. I've asked for a .prj file but the only output available is a Trimble .cal file. Is this any use to me? And, if so, is there any way to make a .prj file from it?

Yes that is my understanding too

Would Alexey's "merge markers' script do what you need?

Have you inadvertently used the camera positions as GCPs by giving them low accuracy figures and/or leaving them checked during processing?

General / Re: DEM export so I can read Altitude (Z, Height) values
« on: July 26, 2019, 05:26:53 PM »
if you double click the layer in QGIS, there's a tab for setting the colour palette to be used.
A good way to extract z values is to use the Profile plugin and add the layer as your values source. You'll then be able to draw a cross section and see the z results from the DEM layer.

General / Optimal strategy for AWS instances
« on: July 26, 2019, 12:23:47 PM »
Having used AWS for the last month and seen the costs racking up, I'm wondering what is the best strategy for running Metashape on AWS instances.

At the moment I have two on-demand instances:
G3.4x.large - for bulk of heavy processing
M5.2x.large - for general work (e.g. aligning GCPs, exporting data)

I then keep a 150Gb volume for project files which can be attached to either machine. And offload outputs to S3 for client delivery.

Questions:
1) as these are currently Windows, I guess moving to Linux would be a good start?
2) are spot instances an option? (it looks like G3 machines are not supported with a hibernate option and also I foresee licensing being an issue)
3) are these sensible machine types as a balance of speed v cost?
