Really odd how all the paths are the ones from my machine @ddthejj ? Is that to be expected? Or some compile/release issue?

[jetXS]

From forum user Tedpallas after recompiling manually (aka not using release binaries)

I rebuilt the plugin locally via the sample project, and can confirm I installed touchdesigner from the dropbox alongsied the old build. With the rebuilt plugin I get this error, which has all local paths:

Q

@tedpallas

What TouchDesigner licence are you using ?

When recompiling, did you use the .bat file or Visual Studio ?

Thanks in advance, and apologies for the issue + all the questions !

A

I am using a Commercial license. I recompiled by launching the project and going through the automated build. Interestingly, the visual solution method wouldn’t load projects for me (0/2 Loaded).

No worries on the questions! Cheers for the rapid responses! Let’s get this cooking fam :sunglasses:

Q

Interestingly, the visual solution method wouldn’t load projects for me (0/2 Loaded).

Ok, that sounds familiar…

Can you try the following point from the doc, even if it is not the exact same issue:

The Unreal related options are missing from the context menu when right clicking the Unreal project file, what should I do ?

This seems to be an install bug, we encountered it on our end as well. With luck, the Epic Games Launcher will show up with a message mentioning to “Fix the project files”, clicking “Fix now” should solve the issue. If the message doesn’t show up, another solution is to open your project using right click → Open with… and open the project with the UnrealVersionSelector.exe located in your Epic Games Launcher install folder (by default, C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64)

It feels like something is not linked properly somewhere.

Do you have Visual Studio 2019 installed?

A

I am using VS2019, yes. I can generate a Solutions file, but don’t get any projects able to load through that solution.

Added a potential fix for the crash in 20093518ba9943f5ffe58b476b94ed8c5411b62b

The local paths are expected, I believe - UE4 saves some built data as local paths, for instance if you load a texture into UE4 and then look at it's source it will be a local path

[jetXS]

Closing for now, as fix is in release 0.9.2 and we didn't hear back from user.

Thanks
