Import Error: DLL load failed while importing _pydna: The specified module could not be found. From Quixel Bridge to Maya Export.

[arain_danishnazir]

I want to export my Meta Human from Quixel Bridge I have exported my Meta Human with UAsset + Source Asset. Export is shown to be successful. But nothing appears in Maya. I have checked the console and this is the error I am getting: 

Import Error: DLL load failed while importing _pydna: The specified module could not be found.

I am using Windows 11 and Maya 2024 student version. I tried to install pydna package with mayapy -m pip install pydna. The installation was successful but still I am getting the same error.

Update: I tried dependencies walker, and it shows me a lot of dll files are missing. I searches for the dll files but people at Stack Overflow suggested I use Dependencies instead of Dependencies Walker as it gives false negatives. 

After using Dependencies, it shows me my python27.dll is missing. I don't know what to do next.

I installed python 2.7, dependencies show no conflict now. but still, I am getting the same error.

After looking at the error line code and looking at dna.py that Swig generated. I know that this is a problem in finding my package or folder. I don't fully understand the code, but I know it's unable to find the module in the current directory. if statement is never true. else is running. I don't know where the else is supposed to import _pydna from. Am I suppose to pip install it somewhere?

If I run the statement in if I get this error in Maya. 

# ImportError: attempted relative import with no known parent package

I have contact Quixel support and they have informed me that Quixel Bridge for now doesn't support Maya 2024. Quixel FAQs

This error occurs when you try to import a module using a relative import, but Python cannot find the module's parent package.A relative import is a way to import a module that is located in the same package or module as the importing module.

To fix this error "Attempted relative import with no known parent package", ensure you have a proper package structure in your project, which includes an __init__.py file in each directory you want to treat as a package. Verify that the directory containing your main script (the one you run) is included in the Python path (sys.path). If you prefer not to use packages, consider using absolute imports by specifying the full path to the module you want to import. Alternatively, reorganize your project structure to adhere to a clear package structure for relative imports to work correctly.
