TouchEngine Plugin for Unreal Engine - Beta Release

lucesintetica · June 17, 2021, 9:12am

that’s one of best days of my life. (virtualive is a very hard bridged system between td and ue4…this means work totally on unreal passing parameters with zero lags or extra routing to send and recieve data)
Thanks derivative you have saved my life. (hours of extra work <3)

i hope to try it soon <3

Hey @tedpallas

This is really an odd one. We have a potential fix that will come in the next beta release, early next week.

Meanwhile, you could try it on the dev branch of the Github repositories if you are comfortable with that.

It should prevent the crash from happening, but the crash itself seems to be caused possibly by an issue with the install… I wonder if (not a joke) you tried to reboot your computer ? What about starting VS 2019 as admin ?

I was also unable to get the plugin to work. I have the correct Unreal Engine version and followed the directions exactly for installing the plugin- The plugins were in the project…I was told to restart to enable the plugins…but when i tried to restart I got the message that the modules were missing but I could rebuild them Upon trying that the error I always got was the project could not be compiled, Try building from the source manually- not exactly sure how to do that.

Hey @audri

Building from source should be fairly straightforward following this

Please let me know if there is any issues,

Best,
Michel

Hello everyone,

Update 0.9.2 is now available for both plugin and samples.

Changes in v0.9.2:

New DAT specific features, see the Plugin documentation for details
Fixing an issue where building the plugin as Release would fail
Fixing an issue where the plugin would cause a crash of Unreal Engine when loading a TouchEngine
Added documentation of C++ for Plugin specific objects and methods
Minor fixes and tweaks to code, as well as some optimization

@tedpallas - maybe you can give it another go and see if your issue is now fixed thanks!

Is anyone else having trouble getting DAT input working? Using BP_TE_UESample03_Parameters from the sample project to send an array of strings into a DAT input does not seem to work. TOPs and CHOPs work just fine when sending data through and printing it back out in Unreal, but not DATs. When reading back the cell with Get Cell, I get the error “Accessed None trying to read property DAT”

Here is a link to a test BP that uses UESample03_Parameters.tox from the sample

Also this is on 14010 and TouchEngine-UE4 0.9.2, UE 4.26.2

JetXS · June 24, 2021, 12:00am

Hello @cerspense

Thanks for the report.

I will add an issue to our repository for a developer to look into it. I will get back to you.

Thanks,
Michel

Issue: TouchEngine-UE4-Samples #33

cerspense · June 24, 2021, 7:10pm

To everyone having problems rebuilding, make sure you have Visual Studio 2019 installed and have the .NET SDK 4.6.2 installed. After I installed these both on a machine, I was able to build it and open the samples project without any problems.

3710tomoya · July 1, 2021, 12:25pm

Can a tox file including compute shader of glsl TOP work in UE4 ??
I just tried that using TouchEngine component, but it seems it doesn’t reflect correctly…

JetXS · July 1, 2021, 12:34pm

Hey @3710tomoya

It should be. Can you elaborate?

You are not getting the expected result once the texture is in Unreal?

Thanks,
Michel

3710tomoya · July 2, 2021, 6:03am

Well, I tried loading with the tox file attached here.
At first, it seems not to work a function like a imageLoad(mTDComputeOutputs[0], ivec2(gl_GlobalInvocationID.xy)).
So I put feedbackTOP instead.But, I couldn’t see same texture of Touchdesigner COMP out in UE4.
I also attached the video here. It’s the result of that.
computeshader.tox (1.6 KB)
computeshaderInUE4

JetXS · July 2, 2021, 1:54pm

Hey @3710tomoya

Thanks for the details.

I played around with your file and was unable to get it to work as expected as well.

I’ve added an issue to the project tracker for a developer to look into it.

Thanks,
Michel

Issue: TouchEngine-UE4 #83

JetXS · July 8, 2021, 6:37pm

Hey @cerspense

The Get Cell issue is solved w/ the TouchEngine-UE4 GitHub repository’s latest commits (main branch).

Thank you for your patience.

Best,
Michel

cerspense · July 8, 2021, 7:27pm

Awesome! Thanks so much!!

cerspense · July 9, 2021, 12:59am

Just a heads up, this most recent version from the main branch was not easy for me to build. I had to install Visual Studio 2017 in addition to 2019, generate visual studio project files and build the project there. Building the plugin with the BAT did not work at all this time.

JetXS · July 9, 2021, 2:09am

Did you get any specific error message that could help or that we could document ?

Did you build manually from the source previously or always used our release binaries?

Thanks,
Michel

cerspense · July 9, 2021, 2:55am

Yeah, here is a log from a failed build with the BAT

Hey @cerspense

Apologies but it would look like something specific to your setup.

I gave it a go again on my end and I had no issue compiling w/ VS2019. I do not have VS 2017 build tools installed on the test machine.

Comparing my logs to yours, I see a few differences. Main one being that the flag -2017 is not passed to the BuildMode.Execute.

But what is more curious is that you are compiling UE4Game here, not the UE4Editor which we want to be compiling. I think this issue could be due to some configurations in Visual Studio.

See VS screenshot below, you should have something similar when opening the solution.

If you want to run the project from VS, make sure that TouchEngineUE4Samp is set as your startup project in the Solution Explorer on the right.

When pulling from Git, you can also always open the .sln and right-click the solution → Rebuild solution, it will compile everything, including the TouchEngine-UE4 plugin.

Yeah its strange, I had the same thing happen on two computers. It pointed me to that log after attempting the BAT method (which threw an error at one point telling me to install VisualStudio 2017). For all previous versions of the plugin, I simply let Unreal rebuild them when prompted after launching the project.
Rebuilding from Visual Studio 2019 does seem to work though, so I will definitely use that method going forward.

Hi.
I tried all the release version. Compiled from sources all the variants of the plugin and I can’t load tox. A similar situation with the project with examples. The process of downloading files and goes for a long time and after I get Warning: Failed to Parse Argument “ErrorMessage” AS A Number (using “0” As a Fallback). Please check your format string for errors: “Failed to Load tox File: {ErrorMessage}”. All Path is right, as the error is repeated and in the project with examples. The second problem is the inability to add the Touchengine component to the usual Actor.
