Physics Overlap/Collision Events Include Triangle Hit Info
Currently the only way to get triangle hit information is from raycasting. This creates a convoluted code flow when trying to ascertain the hit triangle from an overlap or collision event, because both a raycast needs triggered and a check needs to happen to ascertain if the raycast hit mesh is the expected mesh

We have identified this note pertains to our Lens Core engine.
We are currently slated to other priorities but we have taken this note and we will revisit periodically.
Thanks!

Physics Overlap Events include Contact Information
Currently only Physics Collide events include contact information. This makes it difficult to write custom collision responses for when using non-BodyComponents.

DepthTextureProvider is accessible via script
Currently DepthTextureProvider is not accessible via script, causing the need to have a blit operation to a rendertexture with packed floats in order to get high precision depth data to use in script.

Outdated Documentation & Deprecated API - Face Expressions
I'm going through the documentation and this page about Face Expressions shows some code lines that give "deprecated API" warnings in Lens Studio. There's also one dead link "RenderMeshVisual"
https://developers.snap.com/lens-studio/features/ar-tracking/face/face-expressionsThis API page indeed says that "getExpressionWeightByName" is deprecated, but it doesn't say what we should use instead.
https://developers.snap.com/lens-studio/api/lens-scripting/classes/Built-In.FaceRenderObjectProvider.htmlHowever this one says nothing about it being deprecated:
https://developers.snap.com/lens-studio/api/lens-scripting/classes/Built-In.Expressions.htmlIt's a bit hard to know what to use.

Use ChatGPT or Claude to code Lenses. (Context7 MCP with Claude)
Hi everyone, as you might know, editing Lens Studio code with LLMs is a pain as NOTHING is up to date.
There is a new trends now based on MCP and Claude where the updated docs of every tools are on Context7 so Claude answers are always using latest docs.What are your thought on that ? Would be super helpful for everyone to finally unlock this for your users.

User Input for New line in Text Components
Currently it's very difficult to enter multiline inputs in the dynamic text ( Editable Text/ Shareable Text ) as the enter key's native behavior is to confirm the text and not a new line. If we can have something which allows us to input new lines as well that would be awesome. For now I have created a custom keyboard to do the same

Make new windows open next to the scene panel
Currently, every time we open a new window it opens next to the Asset Browser panel, which is very small. It would be good if the default behavior was to open next to the scene panel, in the middle of the screen

LS 5 Asset Library Broken Assets
A handful of the assets in the asset library currently seem to not work properly in LS 5 specifically LS 5.4.1 I am testing them in. It would be nice if the report button in the asset library allowed us to report these there rather than that button only being for copyright infringement complaints.
Here's a list of the one's I know of and any explanation I can provide:
Particles Controller - using outdated gpu particle shader, fails to render on device without updating shader to new version manually
Image Carousel - code is based around the 4.55 screen transform…
1 voteThanks for these detailed reports! We will be looking into the issues on these assets and look for resolutions.
We will also work on putting together a better reporting mechansim here!
Thanks!

Multiple Image Tracking at Once
So wanted to build an experience where I could track multiple images at once but I found out that while upto 10 markers are supported in one lens; at any given time only one image marker can be tracked.

Lag and Too Many Options in Script Graph
I'm a programmer and sometimes teach new-media tools such as Lens Studio and Meta Spark in Taiwan. Most of my students do not have coding skills, so Script Graph is a really nice feature to let them get hands-on making interactive experiences, and is also very easy to teach. (And they like the Patch Editor in Meta Spark a lot)
Although Lens Studio 5 hasn't officially supported Script Graph yet, as someone who is interested and cares about visual scripting, I have tried it out and would like to provide some feedback.
It seems to me that Script Graph does…
1 voteAs you've already commented, Script Graph is currently not supported in 5.0. So the issues you are having are some that are expected to be issues.
We are continuing to review our script graph functions and are working on forging our best path forward. Thanks for your feedback! We will let you know when we have updates!

Add Built-in Grid Overlay for Symmetry in Preview Section
When developing AR lenses, it's crucial to ensure that all assets are symmetrically placed and aligned across various mobile phone screen ratios. To achieve this, I currently upload a preset preview image of a grid to manually check if the entire scene is perfectly symmetrical.
A built in grid overlay in the preview section would be a game changer. This feature could allow developers to toggle a grid directly within the workspace, ensuring precise symmetry across all screen ratios.
This would save time, reduce errors, and help developers deliver perfectly aligned lenses without relying on manual uploads.
Would love to…

More robust LAT debugging tools.
As LAT is now a hard metric for Lens approval, especially for advertising and commercial lenses, we need more robust tools for debugging LAT performance in lenses.
Common issues being seen are large differences between LAT reporting in debugging on device vs reported debugging when a Lens is submitted (often 2x or more).
Even when following the guidelines for remote assets and async prefab loading, these can seem to have little to no effect.It would be great to have a comprehensive list of which specific technologies within Lens studio incur LAT spikes and specific mitigation steps to get these…
1 voteThanks Liam for the thoughtful notes. I know that we discussed this recently in our Open house meeting.
We are continuing to explore ways to make this process better. We will offer updates when possible

Web Hosted AR Lens Frame Rate
Hello! The frame rate on any web hosted lens on mobile is pretty low and would not be suitable for any potential project to go ahead as it's essential the experience is not extremely laggy. Could a fix be implemented so it works this week? Im on a iPhone 12 Pro with safari as the browser and the versions in snap and on a Mac in safari all work with a great frame rate.
A world tracking or simple/light effect like eye colour works better but the rate is still noticeable.
Deployed web cam kit of the same lens works…

I need a separate section for gaming (2D/3D) included in Lens Studio sample projects for better practice.
As the title suggests, we, as users, love creating games. However, for newcomers, even understanding the simplest concepts can be challenging. Having a dedicated collection of sample projects focused solely on gaming would be incredibly beneficial. It would not only make learning more enjoyable but also inspire creativity, enabling users to craft unique AR experiences within a gaming environment.
1 voteHey Joel, this is a great note. Thanks for passing it to the team.
We are always looking for ways to make game creation more intuitive. This is why we recently added the Leaderboard feature which makes the entire game making process better on Snapchat.
We also recently built a brand new tutorial series specifically focused on game creation here: https://www.youtube.com/playlist?list=PL0rDQ-c-_kxcwwBccaz1N9Rmz_xgyijRg
As far as the feedback for more sample projects -- we will consider what is possible and let you know!

Confusion About Layers
As I work on lenses with more transitions and interactions, I’ve become increasingly confused about concepts related to layers. From what I understand, there are render targets, camera layers, camera render order, objects (displayed at the top of the Inspector), and the 3D space in the scene.
I’m having trouble understanding how these elements work together. I hope there can be a clearer, more beginner-friendly explanation for this part.
Thank you!

Face Expression Template update!
The current script for face expressions contains several existing expressions that are not working at all and remain inactive. These expressions need to be fully implemented and activated, as they are currently non-functional. A significant issue is that the head binding for facial expressions is not working correctly in the default template. To resolve this, a new head binding must be introduced and properly linked to ensure the correct operation with the user’s head movements. Additionally, the script needs to be adjusted to fix the default values to ensure consistent behavior. Furthermore, face expressions currently work for only one character’s…

Can't use Leaderboard with Voice ML
This is not described in the docs. Can't use Leaderboard (as it has networking enabled) with some of the privacy infringing stuff like Voice ML. It does give an error in the logger.
