Why does unreal 5.4 freeze at 75% when i use the daz to unreal plugin

[drnooe]

Hi everyone,

I’m trying to install the DAZ to Unreal plugin for Unreal Engine 5.4, and I followed this YouTube tutorial:

I went to David Vodhanel GitHub page, downloaded the latest DAZ to Unreal ZIP for version 5.4, unzipped it, placed the plugin in my Unrael Plugins folder, and copied the DLL into DAZ folder like the tutorial says. Everything looked fine.

Then I opened my Unreal project, enabled the plugin, and restarted Unreal. The issue is that after restarting, Unreal gets stuck at 75% while loading, with a message about Loading PreDefault Modules for Plugin: PythonSciptPlugin.

I found this thread: Stuck on Loading PreDefault Modules for Plugin: PythonScriptPlugin - #19 by mangesh3kt , someone there said to open Task Manager (Ctrl + Alt + Delete) and kill the Python process. I tried it and it opens the unreal engine, but im not sure if the plugin will work properly.

But I don’t understand why? Does anyone know what’s actually causing this and how to fix it properly? I need the plugin working, but I don’t want to have to manually kill the Python process every single time I launch Unreal.

someone there said to open Task Manager (Ctrl + Alt + Delete) and kill the Python process.

that doesn’t sound like a solution to me. i don’t think the plugin will work fine.

try sharing the log here to see more information. it could be busy doing some initialization.
you can try opening the task manager and watching the cpu usage, if it’s high it might be doing some work.
at 75% the engine sometimes compiles a lot of shaders. i don’t know if that would be the case for daz.

also check the network usage. as per this comment it seems daz is installing some modules.
killing the python process would be a great way to corrupt the installation and not being able to easily recover from that.

This is what I’m reading from an experienced user on Discord: “I think what happened here is one of the related plugins uses certain Python related libraries. These used to just be included in Unreal, but now I think the plugin pip installs them when it’s first loaded. One of those libraries happens to be a couple GB in size”. Also “…on subsequent starts, that calculation shouldn’t happen”.

Thank you so much . That was the issue. We’re often in a hurry and want everything to work instantly, but in this case, patience was the key. I verified it by checking Task Manager and noticed Python was downloading something. I let it run for a while, and sure enough , Unreal loaded perfectly after that.
