Hello Yvan. Thank you for reporting the issue!

Could you please provide the following information:

Version of the Python interpreter: python -V
The full output of the pip freeze command.
A full copy of the traceback resulting from starting the application.

The above-described information will help me reproduce the issue on my setup, track down the root cause and possibly release a bugfix.

Thank you!
Maja

Hi @yvanblanchard , thank you for your patience on this matter. I've investigated the issue on a Win10 machine and I've noticed two problems.

It seems that a package compatibility regression appeared with the release of QPanda3D==0.2.9. It broke mouse interaction with the canvas. For now, this can be solved by pinning the version of that package to 0.2.8.

I've successfully reproduced the issue you've reported on a Win10 machine. It does not reproduce on Linux-based machines and seems to be Windows-specific. A difference between path formats seems to be the root cause here, as Panda3D operates on UNIX paths - that's probably why the texture loading issue does not reproduce on my Linux machine 😆 .

I'll dive into this issue this weekend and hopefully release a bugfix. Thanks again for you contribution!

I just found the root cause, and to be honest it's kind of funny.

Turns out that during runtime, the __file__ global variable contained a lowercase lib, instead of the actual Lib directory name. Generally, this shouldn't be an issue, as Windows paths are case-insensitive. However, Panda3D requires the paths to be case-correct, even if the host OS does not distinguish them as unique paths.

The determined texture's path also contained the same case-sensitivity culprit (lib, instead of Lib). This tiny difference caused Panda3D to crash on an attempt to load the requested resource (the left side is the actual, correct path):

pathlib.Path.resolve fixes that kind of case sensitivity issues in Windows paths. I've tested it on my machine and hopefully it'll work in your case too @yvanblanchard . I'll release the bugfix tomorrow 😉 .

I've done some package maintenance and merged the bugfix. Release on PyPI as version 0.1.6. Tested manually on a clean Win10 environment, seems to be working now 😉 .

Please let me know if version 0.1.6 fixes the reported issue also on your setup, @yvanblanchard .

That works fine now. Thank you very much!
