State of ARCore and Geospatial Creator on Unreal #192
Comments
Hey, Since Cesium already works on that engine, I imagine you'd be able to put together some similar tools within Unreal by implementing something familiar to these functions to handle conversions to/from game coordinates and geodetic coordinates. |
Thanks for the quick response @devbridie! And that link is a great example, i'll be sure to investigate with my team mates more when we collaborate next. Would you mind sharing the names of the success stories? It would be fantastic to see if they have any dev blogs or other pointers that we can learn from for how they brought geospatial data into ar as in those links! And it seems in this forum post UE4 from years ago was the last people had much success in doing so: Its been a bit of a deflating investigation so far, so id appreciate it! Then majority of hits I found are from years ago and don't feature geospatial ar projects or showcases in real locations as i find in plentiful numbers from unity's side. Perhaps its because geospatial creator lowers the barrier of entry for indies and mid's viability on unity so people just make the swap even though unreals tooling and visual capacity is incredible and very complimentary to geoAR. From what i've found so far, if we pursued it seriously, realistically we would probably just need to make the switch to unity given the differential in resourcing from google. Thats the choice that some of my dev friends said they had to make in the end even though they were primarily unreal devs. However as I mentioned that would be quite difficult for us to switch, but to tool a feature set that is comparable to what is available with unity stock would be a monumental task for an indie team that could take as much energy as developing the game itself. Otherwise is there any possibility to perhaps open a repo for the community to be able to share any of their tools based form ARCore with each other to save this kind of effort and open resource the community until its officially on the cards for unreal? I know these are very particular questions and requests, but it would be awesome to be able to have the confidence that i felt with Unity for Geospatial AR before making plunge in Unreal, there seem to be a lot of unknowns and it would be hard to have to swap mid way because of an unforeseen limitation. |
Hi there @devbridie, hope you've been well! I watched the latest showcase and announcement videos and have been testing it all. Its fantastic! Really impressed with all that you've been able to do. Particularly the batch locations, addition of more locations in 3d and the path towards universal AR inside maps itself! Very exciting times ahead. Since the previous message I have been experimenting with AR with cesium in unreal. Im trying to get my head around getting this working at the moment as you and some others have recommended, but have been having some trouble! It's certainly not nearly as easy as the unity solution. Unfortunately there don't seem to be any straightforward solutions or examples to be found in UE. By comparison, got it working almost immediately with your Geospatial Creator for Unity 😅 I got in touch with a fairly high up and experienced developer on the Unreal team with background with geospatial tech in unreal. He told me: Im still trying to get this to work as intended. I also got in touch with some of the devs at Cesium and have run into the same issues. VR is certainly possible and there are high quality and detailed guides and examples for that, but no AR. Bootstrapping would be the only solution. At the moment i'm continuing to test this. If the api could be used alongside cesium to achieve what can be done with unity in a much more straightforward way than it currently is in unreal by utilising GS Creator, then it could be excellent to be able to utilise this and perhaps have some examples within the project. To try to get parity with unity capabilities. I know a lot of devs who have moved away from unity to unreal, particularly in the last year. The last I heard, the rate of growth for unreal is much higher than unity. And given the advancements and benefits logistically of unreal now and its ability to port to mobile platforms just as easily, but also with much more online multiplayer support, it's reasonable to assume this trend will continue. With 5.4 it also has significant design and storytelling capacity akin to Aero. Also official support is much better than devs having to bootstrap their own modifications to get a base functional system running: since it comes with support, community knowledge and future updates and features as can be seen with the latest updates and changes with unity. If you can let me know your thoughts, or if there have been any updates on potential target platforms since your latest showcase, that would be fantastic! As that could greatly impact my decision making process :) |
Hi @devbridie I just finished watching some of your geospatial sessions on YouTube. They have been quite helpful!
I would have asked this on the unreal repo, however that was deprecated towards the end of last year.
On part of a team that wants to develop with the features of geospatial creator, however unity doesn't offer the engine features required for our game, amongst other engine disadvantages we have run into. However unreal has everything we need and more.
Ive not been able to find any information regarding these questions online so I thought id ask here:

However there is nowhere near the resource available for unreal and I haven't seen any guides or showcases highlighting AR placement in the real world utilising googles tools alongside cesium which along with some testing leads me to believe it would either not be possible to achieve the same outcomes or would be MUCH more difficult in unreal. So are there any upcoming ARCore updates coming to unreal that would allow for equivalent outcomes? It would be fantastic if so!
We're trying to test viability and get an idea for what is possible at the moment and in the future, so any advice and input would be much appreciated.
Thanks!
