Debugging & Performance

To view the performance in greater depth (beyond what is built into the regular FrameVR menu), add ?debug=true to the end of any FrameVR URL. 

Once you have done this and refreshed, you will have the option to "Open Inspector," which will show you a panel with various options to help you understand how well the frame is performing in terms of draw calls and more. 

About Building in FrameVR + Advanced Interactions

FrameVR Technical Capabilities

iLRN Campus Codex — Engine, interactivity, and 3D asset support

Under the Hood: Babylon.js

FrameVR is built on Babylon.js, a powerful open-source 3D rendering engine. However, FrameVR abstracts most of Babylon.js’s native functionality behind its own interface. Users work within FrameVR’s sandbox rather than having direct access to the full engine.

Advanced features such as complex physics simulations and custom scripting are not directly accessible within the platform. Teams should work within the Action Editor and supported asset formats to achieve interactivity.

FrameVR Knowledge Base & Other Info

FrameVR offers many valuable resources for users building on their platform. Here are a few of the options available:

Help Forum (Discord)

Developer API

Interactivity: The Action Editor

FrameVR’s Action Editor provides a no-code interface for adding interactivity to spaces. While limited compared to full engine access, it supports a meaningful range of triggers and responses:

•         Play Audio — Trigger ambient sounds, narration, or sound effects on proximity or interaction

•         Animate Models — Activate animation cycles embedded in uploaded 3D assets

•         Show / Hide Objects — Toggle visibility of elements based on user actions

•         Open URLs — Link out to external content, documents, or media

•         Teleport Users — Move participants to different locations within or between spaces

These tools are well-suited for guided experiences, interactive exhibits, and layered storytelling within a campus environment.

Access this tool by entering Edit Mode > Click Asset > Open Action Editor > Set Trigger + Action

3D Assets: glTF Format

FrameVR supports glTF (.glb/.gltf), the widely used open standard for 3D assets. Importantly, glTF files can contain embedded animation cycles, which can then be triggered via the Action Editor — making it possible to bring in animated objects (moving parts, characters, environmental effects) without custom code.

Recommended tools for creating or converting glTF assets:

•         Blender (free, open-source) — excellent glTF export with full animation support

•         Sketchfab — browse and download community glTF models, many with embedded animations ( low poly items and Museum-specific https://sketchfab.com/members?segment=organization%2Fmuseum&sort_by=-followerCount )

•         Various online converters for existing 3D models

Gaussian Splats: Photorealistic Spatial Capture

FrameVR supports Gaussian Splat files (.ply / .splat), a cutting-edge format for representing real-world spaces with photorealistic quality. Gaussian Splats are captured using photogrammetry-adjacent workflows and rendered as volumetric point clouds, producing immersive, high-fidelity representations of physical locations.

This is a significant capability for campus-building — real landmarks, architectural spaces, or culturally significant sites can be captured and placed directly into a FrameVR environment.

Capture tools to explore:

•         Luma AI — mobile-friendly capture, accessible for most devices

•         Polycam — supports Gaussian Splat export alongside standard photogrammetry

•         Postshot — desktop processing for higher-quality splat results

[DRAFT: Example soon, check back for update! ]

Note: A Gaussian Splat of a nearby landmark is being explored as a demonstration asset for the iLRN campus — a model for how regional teams might contribute place-based content to shared virtual spaces.

Using Scenes in FrameVR

Using Scenes in FrameVR

Draft Areas, Alternate Configurations & Advanced Scene Management

Last Updated:  April 10, 2026    |     Maintained by:  Charlene Hardin

Codex Section:  FrameVR Build Documentation

What Are Scenes?

Scenes are one of FrameVR’s most useful but least understood features. At its simplest, a Scene is a saved state of your Frame — everything in it, where it is, and how it’s configured. A single Frame can have multiple Scenes, and you can switch between them instantly.

Think of Scenes like different “slides” of the same room. The Frame URL stays the same, but the contents of the space can change completely depending on which Scene is active. Visitors always enter whichever Scene is currently set as the active one.

Why This Matters for Building

When you’re actively developing a Frame, you don’t always want your work-in-progress visible to everyone who walks in. Scenes solve this by letting you maintain a “live” version of the space while building and experimenting in a separate draft state — all within the same Frame URL.

This means you can iterate freely without worrying about visitors stumbling into half-finished layouts, test new asset placements without disrupting the live experience, and preserve a clean baseline you can always return to.

Common Uses

•       Draft mode — Build and test new layouts or assets in a Scene without affecting what visitors see when they arrive

•       Event configuration — Set up a Scene specifically for a live session (with a presenter screen, specific seating arrangement, etc.) and switch back to the standard configuration afterward

•       Preservation — Save a clean baseline Scene before making major changes, so you can always revert if something goes wrong

•       Seasonal or programming variation — Configure different Scenes for different activities within the same Branch House without needing separate Frame URLs

How to Create and Switch Scenes

Important: What Carries Across All Scenes

Not everything is Scene-specific. Certain elements are persistent across all Scenes in a Frame regardless of which Scene is active.

Watch out: Built-in Web Browsers The built-in web browser is one of the most notable persistent elements — if you have a browser open or configured in your Frame, it will be visible and active in every Scene. Keep this in mind when planning your layout, particularly if you’re using a browser for a specific event or presentation and don’t want it to appear in your standard visitor-facing Scene.

As a general rule: if you’re unsure whether an element is Scene-specific, test it in a draft Scene before relying on it in a live configuration. For more information, always consult FrameVR’s Knowledgebase.

Things to Know

•       The Scene that loads by default when someone enters your Frame URL is whichever Scene is currently set as active

•       Switching Scenes affects all visitors currently in the Frame — coordinate with your team before switching during a live event

•       Asset budgets apply across your whole Frame, not per Scene — a heavily loaded draft Scene still counts toward your performance limits even if it isn’t the active one

Recommended Practice for iLRN Builders

Keep at least two Scenes in any Frame you are actively developing:

LIVE	The current visitor-facing version. This is what people see when they enter the Frame. Only update this Scene when changes are ready to go live.
DRAFT	Your active working area. Build, test, and experiment here freely. Keep this Scene clearly named so anyone with build access knows not to set it as active by mistake.

Name your Scenes clearly and consistently. Avoid generic names like “Scene 1” or “Scene 2” — use descriptive labels that make the purpose immediately obvious to any team member who opens the Frame settings.

Advanced Features

Triggering Scene Changes with the Editing Panel

This opens possibilities for guided experiences, event transitions, and interactive storytelling within a single Frame. A persistent navigation element that appears in all Scenes and triggers transitions between them is one practical application.

Setting Items to Appear Across Multiple Scenes

By default, assets you place in a Frame are associated with the Scene you’re working in. However, when editing an individual item, you can configure it to appear in multiple Scenes simultaneously.

This is useful for elements that should be consistent across several configurations — like permanent signage, a logo, navigation buttons, or a welcome poster — without having to duplicate them manually in each Scene.

Quick Reference

Question	Answer
Does the Frame URL change between Scenes?	No. The Frame URL stays the same regardless of which Scene is active.
Can visitors switch Scenes themselves?	Only if you set up an Action Editor trigger they can interact with. Otherwise only admins/builders can switch Scenes.
Do asset budgets apply per Scene?	No. Budgets apply to the whole Frame. All Scenes count toward your total.
Are web browsers Scene-specific?	No. Built-in web browsers are persistent across all Scenes.
Can I make an asset appear in multiple Scenes?	Yes. Edit the item and set it to appear in whichever Scenes you choose.

iLRN 2026 Virtual Campus Canva Projects - Infrastructure

iLRN 2026 Virtual Campus

Canva Project Architecture

Working document — Charlene Hardin, Volunteer Coordinator & Campus Builder  •  April 2026

SPREADSHEET CONTAINING LINKS TO CANVA:

 https://docs.google.com/spreadsheets/d/1dTTy6wOXBb71phRYVhTxZ6nOpveb-wEbZyVvq216lCQ/edit?gid=0#gid=0 

Purpose

This document defines the Canva project structure for iLRN 2026 campus infrastructure assets. Projects are organised by output type, not by room, so that all assets of a given type share consistent dimensions, brand settings, and naming conventions regardless of which volunteer produces them.

Dimensions in this document are working assumptions derived from in-world measurement of existing FrameVR frames and are subject to revision following in-world testing.

1. Canva Projects

Four projects cover all current infrastructure asset types:

Project Name	Canvas Size	Aspect Ratio	Asset Type
Wayfinding Banners	1920 × 320 px	6:1	Overhead/corridor ID strips
Large Boards	2560 × 1024 px	5:2	Main wall display / presentations
Square Posters	1080 × 1080 px	1:1	Branch House artwork, general posters
Buttons & Icons	512 × 512 px	1:1	Nav buttons, GOTO menu identifiers

⚠ Dimensions are working assumptions from in-world screenshots, April 2026. Confirm via in-world testing before producing large batches.

2. Project Setup in Canva

When creating each project in the iLRN 2026 Greece workspace:

Setup checklist for each new Canva project 1.  Create project with the exact pixel dimensions from the table above (Custom size). 2.  Name the project using the convention: iLRN2026_[AssetType] — e.g. iLRN2026_WayfindingBanners 3.  Apply brand colours as Canva colour palette swatches (manual entry — Brand Kit admin access pending). 4.  Add Cinzel, Raleway, and Lato as project fonts. 5.  Name each page within the project by room or context — e.g. House01_Foundations, House02_Assessment. 6.  Do not use Canva's background remover or AI image tools without checking output against brand guidelines.

⚠ Jonathon holds admin access to the Canva Brand Kit. Until the Brand Kit is populated, colours and fonts must be set manually per project. Flag this to Jonathon.

3. File Naming Convention

All assets exported from Canva and uploaded to FrameVR must follow this naming convention. This keeps the campus spreadsheet, Codex pages, and FrameVR asset libraries reconcilable.

Field	Convention	Example
Project prefix	iLRN2026_	iLRN2026_
Asset type	Banner / Board / Poster / Button / Icon	Banner_
Room/context	House01 through House10, or context name	House02_
Descriptor	Brief description, no spaces	WayfindingStrip
Full example	—	iLRN2026_Banner_House02_WayfindingStrip

For presenter content placed in Branch Houses via the Tally opt-in form, the existing convention applies:

FirstInitialLastName_PaperFirstTwoWords

Infrastructure assets (produced by Team A or Canva Champions) use the iLRN2026_ prefix convention above to distinguish them from presenter content.

4. Brand Reference

Apply these values consistently across all Canva projects. Do not use Canva's default palette or theme colours.

Element	Value	Notes
Primary	#1B3B6F — Aegean Deep	Backgrounds, headers, text on light
Secondary	#36BAE7 — Athens Cyan	Accents, highlights
Accent	#E07840 — Agora Orange	Calls to action, warnings, emphasis
Display font	Cinzel	Titles only — decorative
Heading font	Raleway	Section headers, labels
Body font	Lato	All body copy, captions

⚠ The Brand Kit lives in the 2026 Greece Canva workspace but requires Jonathon's admin access to populate fully. Until then, enter hex values manually.

5. Performance Rules

FrameVR performance is the constraint that governs all asset decisions. The April 10 real-world test demonstrated that 19 uncompressed images dropped average FPS from 60 to 10. Every image uploaded to a Frame must go through the compression pipeline below.

Rule	Detail
Compress before upload	All images must be processed through squoosh.app before uploading to FrameVR
2K texture ceiling	Maximum 2048px on longest side for mobile iOS compatibility
Format	Export from Canva as PNG; compress via squoosh to WebP or optimised PNG
File size target	Under 500KB per image after compression where possible
No smoke/particles	Do not design assets that imply particle effects in-world

✓ Design at full resolution in Canva. Export as PNG. Compress via squoosh.app before every FrameVR upload. Never upload raw Canva exports directly.

6. Access & Permissions

Access to Canva projects should follow the principle of minimum necessary permissions. The table below reflects current working assignments.

Role	Canva Access Level	Notes
Charlene (Coordinator)	Editor — all projects	Primary builder and quality control
Canva Champion (per asset type)	Editor — assigned project only	One champion per project recommended
Jonathon (CEO)	Admin — workspace	Brand Kit population pending
General volunteers	Viewer or no access	Receive exported files, do not edit source

⚠ Canva Champion assignments are not yet confirmed. Coordinate with Charlene before granting editor access to any project.
