Pack iteration Texture generation

[Iluvathar]

Hello,

Since the last update, texture generation is taking a really long time, i have a considerable number of iteration packs. Can someone explain the reason ?
Thanks a lot

Hello Iluvathar,

Can you share any sample mesh model to support@agisoft.com which can be used to reproduce the problem, specify the processing parameters used and also provide the processing log from your tries?

Hello Alexey,

I also ran into this issue, do you still need test data?

[Alexey Pasumansky]

Hello wojtek,

If you have the sample mesh that can be used please share it with us along with the processing parameters used and processing log.

I sent it to support@agisoft.com

Hello i'm trying to extract a sample from my work by cutting my scene, i have a 11000 pics scene and selected a part of it, reduced overlap to have just the images of the selected part enabled, the images that are useless are disabled, how can i select all the desabled pictures at once ?

Hello wojtek,

Thank you for sharing the sample data, it is useful for the further investigation. As soon I have any news regarding the problem, I will post an update here.

Hello Iluvathar,

Currently you can do that only using the script:

Code: [Select]

import Metashape
for camera in Metashape.app.document.chunk.cameras:
   if camera.enabled:
      camera.selected = False
   else:
      camera.selected = True

Files sended with wetransfer containing a part of the model with much less pictures, i ran the workflow and had much less iterations, hope it will help

[Alexey Pasumansky]

Thank you for additional data.

Hopefully, the UV parametrization will be fully fixed in the next version update. For example, the model provided by wojtek took about 30 minutes.

I am also having this same issue after the update. Textures on anything processed never complete. For instance I began processing a chunk last Friday, and this morning after 60+ hours the Texture was only approximately 50% complete. The chunk has 1100 photos but i am seeing this issue with any amount of photos.

As a workaround in the version 1.6.2 you can create the following Tweak via Advanced preference tab and set its value to True:
main/texture_enable_legacy_uv

After that select Legacy parametrization option in the Build Texture dialog instead of Generic. Generic option will be fixed in the next version update.

Using Legacy may be a bit tricky, though (see image).

(just tested this, sorry for not replying to the previous email)

Hello wojtek,

Legacy is a way to pass the infinite iterations bug, although the texture atlas is considerably less optimal compared to the Generic parametrization expected result.

[Alexey Pasumansky]

Another possible workaround in the version 1.6.2 is using multi-page atlas with 1000 pix pages, for example, instead of single 8K atlas use 64 pages of 1K atlas, although it might not be an option, if you need a single page as an output.

Hi
Same problem for me.
Legacy works but result is not great.
I look forward to the urgent fix in the next version. 
Many thanks
