Hello!

I am trying to install the ARcore for unreal engine but am having a heck of a time getting it going. I have followed google’s instructions but I always get to the part where you build out the source code in VS2017 and it comes up with a bunch of errors and cannot find the .exe file to run it (even after debugging). I am fairly new to VS and source code, I handle more of the design aspect of projects but I would really like to get this up and running. Could someone direct me to a detailed tutorial or create one for me on how to install arcore for unreal (screen shots would be a huge plus)? It would be greatly appreciated!

With 4.18, you shouldn’t need to build from the source code anymore. I’ve had problems doing that too and it’s mainly always VS that’s causing problems. Try just installing 4.18 and opening up the sample project from Google.

That’s awesome, thanks for that bit of info! To package it out as AR (haven’t got this far obviously ha), would you just set it to android I take it? Or is there a special way to package it out for AR?

Hi, to build for ARCore you need to enable GoogleARCore plugin and have a camera component that has “Lock to HMD” enabled. You can checkout our HelloAR sample here:

Be aware, we just have another developer preview 2 release(Release ARCore SDK for Unreal Preview 2 · google-ar/arcore-unreal-sdk · GitHub) of GoogleARCore plugin. If you want to use the latest ARCore plugin, you need to checkout our Unreal Engine repo(/4.18-arcore-sdk-preview2) and build from source code.

If you don’t want to build from source code, you can stay on the binary version of Unreal 4.18.2, but be sure to checkout the sdk-preview tag(instead of sdk-preview2) to use our HelloAR repo.

Hi Bo,

I checked your Github (I’m new to Github) and I can’t seem to be able to clone the repo… When clicking on the link to the repo (/4.18-arcore-sdk-preview2) I get an error 404. Is that normal?

Thanks!

Hi Chris.
Yes, its a normal issue… you just have to get access to UE4 repo on GitHub.
Please, check these instruction:

Hi,
thanks for your posts. Ive been on that for a few hours. But I failed to see that only two phones could handle ARCORE…
any idea why the google pixel and samsung s8 only can handle the ARcore so far? what’s not yet right with other terminals?

thanks

Hi,

We wanted to get the ARCore preview out as early as possible so that developers could start building and learning as quickly as possible. And each device takes time to calibrate, so we wanted to start with a couple of popular, high quality phones, and then expand afterwards.
