Building on earlier work including out-of-process compositing and multi-layer rendering from v0.2, this implementation allows multiple XR applications to run simultaneously. A demo shows Blender's VR view and the xrgears demo composited together, with Monado handling both OpenGL (Blender) and Vulkan (xrgears) graphics APIs concurrently. Enabling the extension in xrgears required only a small code change. The work was made possible with support from Pluto VR. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I enable XR_EXTX_overlay in an OpenXR application using xrgears? Enabling XR_EXTX_overlay in xrgears requires two things: activating the XR_EXTX_overlay extension and passing the XrSessionCreateInfoOverlayEXTX struct into the graphics bindings `next` field. This was accomplished in xrgears with a small, targeted code change. The Monado runtime then handles compositing multiple application sessions, including mixing different graphics APIs like OpenGL and Vulkan simultaneously. _Developers integrating OpenXR overlay sessions track Monado runtime changes on daily.dev._ ### Can Monado composite XR applications using different graphics APIs at the same time? Yes, Monado can composite XR sessions that use different graphics APIs simultaneously. A demonstrated example shows Blender's VR view rendered with OpenGL and the xrgears demo rendered with Vulkan both composited together as overlay layers using the XR_EXTX_overlay extension, with Monado handling the cross-API frame submission transparently. _Teams building multi-app XR platforms keep up with Monado's graphics API support on daily.dev._ ## Similar posts on daily.dev - [Godot OpenXR Vendors plugin v5.1 – Godot Engine](https://daily.dev/posts/godot-openxr-vendors-plugin-v5-1-godot-engine-7j3aecljv) · Godot · 1 upvotes · 0 comments - [New OpenXR Validation Layer Helps Developers Build Robustly Portable XR Applications](https://daily.dev/posts/new-openxr-validation-layer-helps-developers-build-robustly-portable-xr-applications-lqtmbxscq) · Khronos · 0 upvotes · 0 comments - [Google’s Android XR Is Here: Here’s What Developers Need to Know](https://daily.dev/posts/google-s-android-xr-is-here-here-s-what-developers-need-to-know-ulgk8meif) · Medium · 0 upvotes · 0 comments - [Godot XR update — March 2026 – Godot Engine](https://daily.dev/posts/godot-xr-update-march-2026-godot-engine-kubg0ieps) · Godot · 1 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#openxr](https://daily.dev/tags/openxr), [#vr](https://daily.dev/tags/vr), [#vulkan](https://daily.dev/tags/vulkan) [View this post on daily.dev](https://daily.dev/posts/monado-multi-application-support-with-xr-extx-overlay-t6sxxhxly) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Monado: Multi-application support with XR_EXTX_overlay","url":"https://daily.dev/posts/monado-multi-application-support-with-xr-extx-overlay-t6sxxhxly","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/monado-multi-application-support-with-xr-extx-overlay-t6sxxhxly"},"datePublished":"2026-08-11T08:53:39.017Z","dateModified":"2026-10-15T02:23:39.745Z","description":"Monado, the open-source OpenXR runtime, now supports multi-application compositing via the XR_EXTX_overlay extension.
