OBJ Texture Disappears After Removing a Cross Section

[Jay_Ki]

Hello,

I would like to report a possible bug related to OBJ textures when using the Cross Section tool.

The issue can be reproduced as follows:

1. Open an `example.obj` file that has a texture.
2. Use the **Cross Section** tool to cut the model and create a section.
3. If I am not satisfied with the resulting section and remove/delete it, the texture of the original model disappears.
4. Once this happens, I have to restart CloudCompare and reopen the model to restore the texture.

This issue seems to occur specifically with OBJ files. I have tested the same workflow with PLY and GLB files, and the problem does not occur with those formats.

For simple tasks, restarting CloudCompare and reopening the model is only a minor inconvenience. However, if this happens during a more complex workflow involving multiple processing steps, it can become a significant problem.

I would like to know what might be causing this behavior and whether it is something that can be fixed.

Thank you.

Good catch. What is the date associated to the 2.14.beta version you add the issue with?

(I can't reproduce this issue on my side at least, with the latest 2.14.beta version of the 13th of September)

I guess you are working on Windows, but what is your graphic card model? (you can see it in the console on startup, and also the OpenGL version, etc.)

CPU : i7 10700F
GPU : NVIDA GEFORCE RTX 3070
GL VERSION : 4.6.0 NVIDA 580.97

Almost the same as me then... Strange.

I'll have to look at the code and try to imagine what can go wrong...

[daniel]

Ok, this should be fixed now! You can test the latest 2.14.beta version on Windows.

It works. Thanks for your services!
