DASH 18.5 is not initiating in UE 5.5

During installation I noticed some problem in my Window 11 Pro (24H2). DASH installation has done fine but after installation is finished, one popup is there to wait for console intallation. I pressed OK and wait for console installation but during that time I have noticed it is trying to install something in forbidden areas or socket. I don't know what that mean but then all consoles are terminated by Windows and some lines are there in red color. It was so fast that I can't read out. Is DASH 18.5 have any problem with Windows 11 Pro (24H2) or my Anti Virus System which is Kaspersky Total Security ?

Hello! This new console windows that are popping up in the end of installation is python dependenceis installation. We moved this process to instsaller (previously it was happening during unreal project startup). The reason to move was that we started affecting startup time a lot, and everytime we add new dependencies this will only grow.

Regarding installation, there is nothing forbidden being installed, and we install those dependencies into Dash installation folder (by default it's DASH_INSTALL_FOLDER\Plugins\UnrealEngineContext\Imports\thirdparty\PYTHON_VERSION\DASH_INSTALL_FOLDER\Plugins\UnrealEngineContext\Imports\thirdparty\PYTHON_VERSION\

Here is what you can do to validate installation.

Check that unreal plugin is installed to selected engine (UE_ROOT\Engine\Plugins\Marketplace\GraphNUnrealPlugin\UE_ROOT\Engine\Plugins\Marketplace\GraphNUnrealPlugin\)
Validate that you can see Dash icon on the toolbar
If so, click on it
If nothing happens, open output log window in Window->Output LogWindow->Output Log menu
Go to Dash installation folder and find InstallationLog.txt, share it here

Here you can find an overview on what python modules are being installed on that console window

dash-generalHi. Our programmers are very restrictive

we've added a few more recently - openai, anthropic and torch. stuff to work with AI, for our AI assistance for example

Also you can try to reinstall like this:

Search "Uninstall Dash" in windows search and run it
Run installer as admin

It's important to uninstall from windows shortcut, and not from "Add or Remove Programs"

Problem solved. It was due to Firewall problem. Now I installed Dash 1.8.6 and it is working fine. I have two questions: 1. The new repetition braker for material in terrain material is not showing after I close the terrain and went for some tree scattering. Only scatter tool is showing in edit panel. 2. I used to use Ultimate Level Pro to biuld architecture from scratch. Dash has almost similar rather higher productivity tool inside it. Why you're not adding such dedicated panel for architectural modelling with some similar nut and bolts as in ULP tool? I think this is time to look into it as you already incorporate procedural stuff in Dash as shown by that Procedural Bridge video.

Great! @kanchu9573

In order to access Material Edit, you need to select your Surface and then open the list of active tools in the Tools Panel. See my video
I can't find this ULP tool, can you link it?

kanchu9573OP•2/26/25, 4:58 AM

I did the same but no material editing tool is there:

I mean tiling braker tool hare.

Kkanchu9573 I mean tiling braker tool hare.

ahaa, then you are missing a material update.
Can you restart Unreal, and make sure when it opens, it opens into a empty UE level, and not this level?
Then click the Dash icon and you should see an popup mentioning material updates

kanchu9573OP•2/28/25, 9:59 AM

It is not getting material update or any pop up is coming after I opened UE with blank scene. Even I uninstalled the Dash and installed it again, but same thing happened. No material update. Could you please give me the link from where I can download the update.
