I’m just trying out the touch/UE5 integration but i can’t get any tox files to load and i see this error

I opened a brand new UE 5.7.2 project with the TouchEngine plugin 1.7.0 installed

Created a new blueprint using class TouchEngineActor, dragged in my tox files and when i add them to the blueprint properties i get the above error. i tried different tox files, even from the samples provided.
The Touch Engine process is loaded from the latest build 2025.32280

Windows 11

RTX 5090

Ryzen 9 5950x

Hi @sypher

I wasn’t able to reproduce.

Can you please share in which RHI your project is configured?
Can you confirm the samples project works as expected?
Are you using any Environment variable, such as TOUCH_10_BIT_COLOR ?

Best,
Michel

Hi, this is the first error i get when i try and open the sample project

if i click yes, TouchEngineUESamp could not be compiled. Try rebuilding from source manually.

the RHI is directx12

i haven’t set an env variables manually so unless they’ve been added by the installer it should be whatever is standard.

You need dev tools to compile.

# FAQ

If errors occur the Message Log window should pop up automatically. However if it does not then you can manually open it via Windows->Developer Tools->Message Log.

## 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`)

## I am getting an error mentioning map/lighting, what should I do ?

Rebuild the map/lighting to fix the error that comes up when loading the project.

## The examples seem to load forever, what should I do ?

It can take about 5-10 seconds (subject to change based on hardware) for the subprocess to boot and TouchEngine to load the .tox within Unreal Engine.

## I just pulled the git repository and got some updates, my project is now starting with a lot of errors, what should I do ?

If you had compiled the plugin manually, chances are that it is now using an older version of the plugin while they are potentially new features in the Unreal Engine project. You can either grab the latest plugin version on our release page in the plugin repository, or re-compile manually the plugin.

How did you get the samples project on your machine?
You didn’t clone with submodules did you?

git clone --branch UE5.7-Release --recurse https://github.com/TouchDesigner/TouchEngine-UE-Samples.git

sypher · February 2, 2026, 11:15pm

hmm no i just copied the sample project to my machine and tried to open it.

Your logs point to missing files.

The instructions are documented on Github.

If you download the release zip, they don’t include the plugin. You need to add the plugin to the project.

Otherwise, you clone.

If project does not open, rare but possible, it means that the precompiled binaries need to be recompiled for your machine. You need the Visual Studio dev tools for that.
