I’ve been trying to get into lightship dev lately and, boy, life isn’t easy. I really want to love this SDK and it has a lot of really promising features but, shucks y’all, you’re making it hard…
I’m an experienced XR dev and I don’t think I’ve ever encountered such a painful mismatch between expected behavior (based on the plentiful docs and tuts) and actual SDK behavior. Respectfully, I think it would behoove whoever owns your learning resources - to dogfood the tutorials from scratch with 1.1.0, and particularly the
getting started and
virtual studio materials, because I’m seeing many of these problems echoed across the forums. I think the latest version might be seriously broken across multiple areas, Unity versions and OSs.
To confirm the prerequisites, I have (in multiple projects, multiple times, in multiple OS’s, and multiple versions of unity, including 2019 LTS, 2020 LTS and 2021 LTS):
- created a
Resources/ARDKfolder at the root of my project and added my API key
- set the build target to either iOS (OSX) or Android (PC)
- created an
ARDK_MockWorldlayer and assigned it per the instructions to the parent mock world prefab and every child recursively (anytime I try to use one, that is)
- followed various tutorials (primarily “getting started”, “virtual studio” and “meshing”)
Now, the following is consistently broken for me on both OSX and PC:
ardk_client_platformerror. Every time. Everywhere, incl. OSX. (Full error attached below)
When running the Semantic Segmentation, Depth and Meshing examples (the only feature-specific ones I’ve tried), the relevant buttons disappear and I’m getting a black screen (see screenshot below). This is out of the box in both OSX and PC. Aside from the
ardk_client_platformthing, no other errors.
Virtual Studio simply does. Not. Work. That is to say:
mocking does not work at all, under any circumstances, except the example mock scene which explicitly sidesteps the Unity interface for mocking!. And even then, I’d expect in-editor meshing of the mocked prefab? Plane recognition? Nothing happens, although I am able to navigate the scene as explained (mouse+keyboard, etc). Not sure what the expected behavior is.
Interestingly, setting up mocking based on the tutorial video does work - but adding mocking to any of the example scenes doesn’t.
edit: I was able to get mocking working in the plane anchors scene! I also noticed the mocking docs only discuss planes. Is plane detection available via mocking whereas depth, segmentation, meshing etc. aren’t? If so, I think it’s really important to point out…
Remoting does not work at all, whether via USB or internet, both on PC and OSX. I’m able to build the app just fine, but it never connects.
Finally, this forum system seems to be broken . I’m not getting notifications for replies to my threads, so I have to check in manually after I post. Which… is not great.
Additional validation of the various issues:
ardk_client_platform completely inhibiting development
I know most problems are typically user-side but I’m pretty sure I’m not doing anything wrong repeatedly across all attempts - perhaps the tuts and videos need to be updated?
At this point I can’t get remoting to work, can’t really get mocking to work, and the examples aren’t documented enough to make the lengthy tweak-build-deploy cycle any less painful.
With so many great alternatives around, I really hope lightship dev gets easier and less buggy in the future, because I do love a lot of the features, and would love to consider it for my next app. Thank you.
