World Tracking in Camera Kit

[keen sigil]

What are some good tracking solutions for Camera Kit? Fx. does the World Mesh work? And what did you end up doing? I need to place something on the ground or table in front of a user and I found that the World Object Controller is unreliable for this.

@keen sigil is this for Mobile or Web SDK? I presume Web?

[keen sigil]

It's for web and possibly mobile too

Logged your last point as feedback for our PM team! I'll forward your question over to our Eng to get you an answer.

We also have office hours today in.. about 2 hours if you want / are available 🙂

@keen sigil Did you ever get an answer for this? I find that camera kit doesnt work with world tracking at all. It works fine in snapchat but when its published to our app using camera kit its all over the place

@tidal fractal Do you still do office hours? Is there anyway I could chat to a dev about a really quick question?

[keen sigil]

No maybe @wheat tide knows

I'm finding it really hard to get in touch with any Snapchat staff that can look into this potential bug, its one of the most important AR features in my opinion and without it makes Camera Kit unusable for world placement AR.

Their main focus seems to still be on face filters as it’s driving the business. But I’m pretty sure Sam got something working in the end?

That’s a shame, it’s so close to working they just need to allow us to turn off the default on tap behaviour and it will be fine. Hopefully @wheat tide sees this and can help.

[wheat tide]

what is the problem you are working on @weary garnet ?

[weary garnet]

I am trying to disable the surface tracking default behaviour which moves the scene on tap. I have a scene which allows you to drag items and press buttons but everytime you press a button the scene keeps moving due to the default behaviour.

This code only seems to work on Snapchat and WebAR. It doesn’t work on camera kit

function onStartScript(event)
{
    // Stops default snapchat touch interactions - kept moving scene around
    global.touchSystem.touchBlocking = true
}

const onStartEvent = script.createEvent("OnStartEvent");

onStartEvent.bind(onStartScript);

Oh yes this is a bugger. I didnt find a way around it. I just ended up using a less than ideal solution with the world tracking option enabled over surface tracking. This def feels like a bug. File a report!
