AR Small characters

Hi

So I am making a tower defense game in AR with UE4 and I am having issues with the AI.

Since I am using AR I want the play area to be projected on to someones table or desktop, which means it is pretty small, may like 30cm2 map size. Getting the AI set up for something so small is becoming a pain, where they often don’t recognise paths, hover above the floor etc. I’m putting this down to the characters being really small,1cm radius small.

I was wondering is there any way around this or a better process I could be using? I have tried, streaming in levels and adjusting their location and size but I am getting mixed result with that. I have set up a small agent for the nav mesh too and that has solved some issues at the start but not all.

I am hoping unreal have though of this, because I am guessing AR games will be using quite small map sizes since they scale to real world units.

Thanks

I can’t be sure if this will help but look at World to Meters in the VR tab under World Settings. I think that might help “universally scale” everything, I’ve been looking for a similar answer to your question as I have large scenes that need to be table size and scaling them down to 0.1 or 0.01 inside of Unreal causes all sorts of problems.

When I made my small world demo, I use World Scale and just scaled to 10 instead of 100 and it worked perfectly. I imagine how hard it would be if I would work on tiny scale.

I tried that and I couldn’t see any difference. Could you give me an overview of your process?

we tried. Sadly it does not work for AR, only for VR.
