Send to Unreal - How To Stop "No Unreal Editor Connection" Error

[WindsweptWyvern]

• Addon: Send to Unreal
• Question: How do I completed the setup so I don't receive the "No Unreal Editor Connection" error?

Hello, I'm having the worst luck with getting the addon to work. After days of trying to troubleshoot I thought I'd ask here before accepting my fate.

Whenever I try to push an asset or add a folder path to the export settings I receive an error saying there is no connection to the unreal editor. Trying to push an asset will freeze blender for a second but ultimately do nothing.

Unreal Version: 5.1.1 Pugin Version: 2.3.1 Blender Version: 3.3

I have the following settings in Unreal Engine:

• Python Editor Script Plugin enabled
• Editor Scripting Utilities enabled
• Groom enabled
• Alembic Groom Importer enabled
• Python Remote Execution enabled - Multicast Group Endpoint 239.0.0.1:6766
• Support Compute Skin Cache enabled
• Use Less CPU when in Background disabled

I've tried the following plugin versions:

• 2.2.0
• 2.2.1
• 2.3.0
• 2.3.1

I've also tried the following troubleshoot methods:

• Ticking "remote execution" on and off
• Making sure firewall access was given (even tried turning firewall off temporarily)
• Ran the netstat -an|sls 6766 PowerShell command prompt before starting Unreal. Received UDP 0.0.0.0:6766 : on the second run. I also tried -an|sls 9998 but it did not come up with anything.
• Ran netstat -ano. Unreal Engine has an active connection with 6766 when open. No active connection for port 9998.
• Checked the Blender and Unreal logs but did not see anything
• Tried restarting Unreal, Blender, and PC

Any ideas?

Can you add REMOTE_EXECUTION_SHOW_PYTHON=1 SEND2UE_DEV=1

To your system environment variables and then shutdown blender and relaunch and retry and paste the blender output when you run the push assets op here?

Also another thing to try would be run this in the unreal python console after you have tried running the push assets op from blender.

import threading
from pprint import pprint
pprint([thread.name for thread in threading.enumerate()])

And paste the output here

[WindsweptWyvern]

Sure thing. I was able to get a very lengthy log of failed connection attempts after adding the variables. I just gave them a letter Value.

I also tried the unreal python console after pushing but only received this: LogPython: ['MainThread']

Here is the blender log:

Can you paste this in the unreal python console?

import sys
import os
import threading
for thread in threading.enumerate():
    if thread.name =="UnrealRPCServer":
        thread.kill()
os.environ["RPC_TIME_OUT"] = "60"
sys.path.append(r"C:\Users\Owner\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\send2ue\dependencies")
from rpc import unreal_server
rpc_server = unreal_server.RPCServer()
rpc_server.start(threaded=True)

This should start the server on port 9998 (check with netstat)

Also verify the server thread is running running by looking for "UnrealRPCServer" when running this in unreal python console.

import threading
from pprint import pprint
pprint([thread.name for thread in threading.enumerate()])

If both those look good then try runing the tool from blender. (use 2.3.1 of addon btw if not already)

It worked! Thanks so much for your help. It's good to find a resolution after a few days of trying to figure it out.

[james-baber]

Ok cool, yea once your project is shutdown youll need to run the snippet again to start the rpc server. That initial snippet to start the server should be happening automatically across port 6766, so I dont know why that is not working for you.

If this persist you can create a init_unreal.py with the code to start the server for you, and then you wont need the remote execution option from the python plugin

Hi, im having the same issue but when i do the code that worked for WindsweptWyvern i get: LogPython: Error: Traceback (most recent call last): LogPython: Error: File "string>", line 9, in module> LogPython: Error: ModuleNotFoundError: No module named 'rpc'

[james-baber]

This path needs to match where your folder is

sys.path.append(r"C:\Users\Owner\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\send2ue\dependencies")

Are you using a blender installed from blender.org?
