i am trying to use your tools, but whenever i try to click on “Update List Skeleton” i got this error message:

Traceback (most recent call last):
File “C:\Users\hng8\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\UE4Workspace\UE4WS_Character.py”, line 371, in execute
skeletonList += json.loads(output"output"][0]“output”])
IndexError: list index out of range

location: <unknown location>:-1

#3

Thanks for report

Can You open your Unreal Engine project > File > Recent Python Script > Select “GetAllSkeleton.py” > Check Your console, You should be get all Your skeleton in array string

tell me what you get ??


​


​

#4

in Unreal Engine > Recent Python Script is empty, seems like GetAllSkeleton.py doesn’t able to execute remotely in UE4.

if i open my output log in UE4, this is what i see when i click on Update List Skeleton
LogPython: Error: SyntaxError: invalid syntax (<string>, line 1)

#5

can you edit UE4WS_Character.py
search for


output = self.remote.run_command(os.path.join(os.path.dirname(os.path.realpath(__file__)), "PyScript", "GetAllSkeleton.py"), exec_mode="ExecuteFile")

and add


output = self.remote.run_command(os.path.join(os.path.dirname(os.path.realpath(__file__)), "PyScript", "GetAllSkeleton.py"), exec_mode="ExecuteFile")
print(output)

to know output from Unreal Engine.

open Blender > Connect to Unreal Engine > Update List Skeleton > Window > Toggle System Console > See what the output ??

#6

looks like the output is empty:

Traceback (most recent call last):
File “C:\Users\hng8\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\UE4Workspace\UE4WS_Character.py”, line 371, in execute
self.remote.close_command_connection()
IndexError: list index out of range

I’m kinda confused right now, can you make some video how your workflow.
It’s hard to debug when I can’t see someone workflow.

#8

Hi Anas,
i manage to solve the problem, all my blender addons were installed into:
C:\Users\hng8\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\UE4Workspace
i think there was a space in the middle causing the python script to behave incorrectly.

now i change my addon into a new folders without space like this:
C:\Users\hng8\Documents\Blender\Addon\addons\UE4Workspace
and the script is working correctly now.

:slight_smile:

#9

Ah… folder issue, thanks for report this issue
I will figure out for this issue ASAP, I’m not having this issue because I’m using Portable Blender and all add-on install is not going to %APPDATA% on windows

thanks for bug report, try to change multicast group endpoint port

Unreal Engine 4

Edit > Project Setting > Plugin | Python > Expand the remote execution and change the port of multicast group endpoint

Alright first of all great job on this blender plugin it is truly amazing and has improved my workflow tremendously and I want to thank you for this amazing plugin. and the issue where you couldn’t import big project assets is now fixed I tested it from the master branch.

#17

Hi. could you add an option to combine child meshes into one mesh before exporting?

Otherwise they will be imported separately, and cannot be merged together in Engine.

Your plugin is absolutely great! :slight_smile:

Hello Anas Rin.

I found your script while searching online for a way to add sockets in blender and have them carry over to my unreal project.
This functionality will save me a lot of time while working on my project. Using the latest versions - Blender 2.93 and UE 4.27.0, I was able to connect to UE from Blender, but it didn’t display the “list project” drop down. Exports didn’t work - I tested with just a basic cube.
On Blender 2.91, I could see my project and the correct engine version, however clicking export didn’t send my files to Unreal - no errors and nothing under “Recent Python Scripts” in UE.
It also didn’t work on UE 4.26.2 and finally I was able see my exports in my unreal project on version 4.25.3. The FBX files appeared in my export folder normally on all versions.

Any ideas on what could be the problem or any plans to update the script to work on the lastest blender/UE versions?
