ARkit on Windows?

[HEGI]

@XsynthZ

I don’t know what you guys are all talking about. I built an ARKit project from preview 4 on Windows 10 no problem, no remote-build required.

afaik, the engine comes pre-compiled with ARKit enabled by default. As long as you don’t need to enable/disable any plugins, you shouldn’t need to recompile the engine. If you do (which you should, as there are a ton of android plugins enabled by default aswell), Xcode will be required. This is when you’d need to either work directly on a Mac or use remote build.

You can package a ARKit App on windows, but afaik when testing on a device, it crashes. Does it work on the device with the windows build ?

@HEGI does it build and launch to the iPad or just crash when you try to run it?

I’d like to know more then @XsynthZ as I’ve seen a fair few people say ARKit is Mac only at the moment, but that was 4.17, Are you saying it’s now “universal” in 4.18? and no need to build from a Mac?

Yes, so far in 4.18 prev4, I can package and launch AR apps on apple devices without any mac involved.

So far I am able to package and launch AR apps without a mac on 4.18 prev4 as well. I’m stuck on how to get the camera on the phone to activate the background. In previous versions there was an “Apple ARKit Camera Texture,” but in prev4, it appears to be gone. How do I get the camera to project onto my skybox now?

Update: Nevermind. I figured it out from this post: https://answers.unrealengine.com/questions/708873/using-arkit-with-418-preview.html

What’s more to it, confirmed info regarding 4.18 API changes and sample project below:

Not having a device to test right now. But according to the posts above it seems to work fine now on windows.

Anyone tried the release 4.18? Now is asking me to configure a remote mac… :S

[DMHokie]

Same here. I was able to do this all without a mac in the preview, but I just updated to 4.18 and it is now asking for a xcode/mac to launch it…

[Naitguolf]

What I did, was to download the updated sample, then used an empty project file and open the project from there. Now I deleted everything related to android and now I am able to compile without mac. IT seems when android AR plugins are activated, for some reason UE asks to recompile, but if your project only uses arkit, its fine.

[DMHokie]

Ah, that worked for me. Thanks.
I’m having an issue now where it seems like any FBX file that I bring in does not display work when launched to the device. Any engine content, like sphere, cube, cone, show up fine and can place those, but when I place another FBX asset in the scene and launch it, nothing appears on the launched device.

Can anyone tell me how to provision with only the free Apple account?

I don’t believe you can, I had to fork out the cash for an account but I was in a rush at the time and don’t know if it can be done for free. I doubt Apple knows what free is though so I doubt it.

I’m getting these log messages in 4.18.0 and 4.17.2. with the two ARSample scenes I’ve been able to download.

LogPlayLevel: Picking the default remote server
LogPlayLevel: ERROR: Remote compiling requires a server name. Use the editor (Project Settings, IOS) to set up your remote compilation settings.
LogPlayLevel: Doing xcode-select --print-path

Still looking for a remote server mac to compile.

Hi,

has someone managed to launch the AR-Sample on an iOS device from windows with the binary build ofUE4.18.1?

I am getting this error:
LogPlayLevel: ERROR: Stage Failed. Missing receipt ‘ARSample.target’. Check that this target has been built.
PackagingResults: Error: Deployment failed! Missing UE4Game binary.
You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UE4Game <Platform> <Configuration>

I am guessing it’s asking for xcode but I thought there is a way to launch it on windows without using the remote build option?

[CGough]

@Tyrus86 Nope sadly there’s no way to compile xcode without a remote mac or virtual machine.

4.22 simple ar sample, does not export to ios, but any other template works fine
