All previous models open with no texture in V1.74

[Landy]

G'day all,
I reported a problem the other day associated with UV mapping causing 'fuzzy' patches in version 1.74.  I rolled back to 1.73 as I had some deadlines.  I have now reinstalled 1.74 (build 13028) and the texture problem appears to have gone, however the vast majority of my previous models (except some files several years old) open with the texture apparently missing - they open to 'solid model' view by default, and the 'textured model' option is greyed out (as is model confidence).  This happens even with a test run generating the texture in 1.74, saving the file, but the texture is gone on reopening the file.   They all open fine in v1.73.  I am wondering if has something to do with texture size - the majority of my models have a texture size of 8196.  My video card is an Nvidia RTX3070, so it should have no issue displaying the textures.
Any ideas what is going on here?  Help!
cheers
Bill

Hello Bill,

Would it be possible to share two projects to support@agisoft.com - one with the texture generated in the older version and another after re-saving the project in 1.7.4 with the "lost texture"?

We haven't been able to reproduce the problem on our side in a meantime.

Thanks for your response Alexey.  The files are pretty large (~0.5GB each) so I have uploaded them to onedrive (link below) - wasn't sure if there is a size limit to upload directly here.  It might be worthwhile mentioning that I use DNG format for imagery almost exclusively.  Maybe that is the source of the problem, but it has never been a problem before.  This really has me puzzled!  Two files are in the onedrive folder - "sample 1 1.74 test.psz" was processed with v1.74 - it shows the texture immediately after processing, but texture is missing when the file is reopened.  The other file "sample 1 v1.73.psz" was processed in v1.73 and reopens fine in 1.73, but opens with the texture missing in 1.74.  I can supply the DNG files if necessary, but they are roughly another GB.  In the meantime, I'd just be interested to see if these files open with the texture for you.  I don't have another PC to test them on at the currently as we are in covid lockdown.

Hello again Alexey,
I have been doing some experimentation and reran this project using jpegs.  The result was the same  - worse actually, because the 'fuzzy' patches of texture (UV mapping problem?) reappeared (see screen capture attached).  And the file still reopens with no texture.  I have uploaded a zipped bunch of jpegs and another psz file run from these jpegs (Prac exam Q3 sample 1 1.74 jpeg test.psz) into the same ondrive folder I provided a link to above so can see if you can reproduce the problem.

p.s. I just notice you asked me to email links to support - I have now done that also.
cheers
Bill

UV mapping is broken in 1.7.4, see here: https://www.agisoft.com/forum/index.php?topic=13701.0

Yes, that was my initial query.  So you are having the same issues wojtec?  Glad it's not just me!

Hello Alexey,
Just to report back, support have confirmed this is a software issue and are working on a fix.  I'm just glad it wasn't something wrong at my end!

Hello all,

We are planning to implement the fix for UV parametrization in 1.7.5 update.

[jedfrechette]

Is there an ETA for 1.7.5?

I had hoped we would be able to upgrade to 1.7.4, but the broken UVs is a pretty major bug that currently prevents that.

[Alexey Pasumansky]

Hello Jed,

I think 1.7.5 will be officially released not sooner than the first decade of October.

[Alexey Pasumansky]

Hello all,

Please check, the pre-release version of 1.7.5 (build 13151) which should include the texture parametrization fix:

Hey, Thanks!

I've tested this and while the critical errors seem to be gone the parametrization is still off compared to 1.6.6.

A lot of small islands are generated for no reason(?). What is the primary benefit of the new UV mapping method?

Edit: Can we have a tweak that reverts the parametrization method to the old version?

-------------------------

Thankyou for supplying those links Alexey,
I have just given it a try and the 'fuzzy' patches problem in the texture appears to be fixed, however I still have the problem that all of my previous files open up with no texture visible.  I have saved re-textured version of the test file I uploaded before that I retextured with 1.7.5.  Note that it still reopens (in 1.7.5) with no texture visible.  I rolled back to v1.7.3 and the file opens fine with texture visible!
The file is in the same onedrive folder I supplied a link to before and is called "sample 1 1.7.5 jpeg test.psz".

Hello Bill,

It seems that for some reason the texture is not shown, when the project is saved in PSZ format. The problem will be fixed in 1.7.5 release update.

Thank you for the response Alexey.  Glad it isn't just me.  I thought it was odd, because when you inspect the psz in a zip utility, the texture is definitely there!  I didn't try saving as psx.
Thanks again.
cheers
