ATG Failed with Leica E57 file
I am trying to create an area target from a Leica BLK360 scan. I've followed all the steps successfully and managed to create a proper Area Target from a smaller sample of the scan. When I try to create an area target from the full 1.5 GB E57 file, the Area Target Generator fails with no error message. Please, see the screenshot for details. It fails after it generates occlusion mesh.
Any idea what could be the problem? There is enough empty storage on disk (60GB) and the previous, partial model worked just fine.
we are having trouble generating an area target from a E57 file. (Storage error, see attached image)
We ran the tool on several windows machines and a mac with ATG 9.8.5. The capacity of the target drive was more than 100GB in all of these cases. We double checked the write access and ran the tool as administrator.
The size of the file we were trying to convert is 200MB.
Best practice for multiple targets
I am currently developing an application with multiple, independent area targets.
I have noticed that the APK size grows by about 25 MB for each new area.
Is there a way to download the area targets and its child objects or even the whole scene on demand form a remote server?
The problem is that if I try to use asset bundles, let's say, they don't really work with scripts as far as I know, so scripting the child objects and all the AR interactions for each area target becomes problematic. Not even sure if it's possible with Vuforia.
Occlusion works in simulation but not build
I encountered a problem, where occlusion doesn't work for the area target and its children objects, only on Android build (haven't tested iOS).
Occlusion works just fine in the simulator mode in Unity and there doesn't seem to be any problem.
To make it clear, I added occlusion mesh in the Editor (AreaTarget game object options) and haven't done anything extra (which worked in Vuforia 9.7.5 and Unity 2019.3f4)
Some additional information:
Unity version 2020.31f1
Android, Galaxy S20 FE
