Thank you. The problem is that we want to integrate Noesis to our VR Pico4 (Vulkan) experience which is developed in UE5.1 but now we are testing UE5.4 and UE5.5 but we ran into problem with World Space UI component and were wondering if the problem is within SDK or smth else. It works using view in widget and plugin itself works. We really dont want to use UE5.5 because Pico SDK is only for 5.4 and we get around 30% worse performance in UE5.5 with everything switched off and all settings copied from 5.4

Error we get in UE5.4 is.

Assertion failed: IsInRenderingThread()
You're doing rendering work (like creating a render view) likely from the game thread or a Slate tick, but Unreal expects it strictly in the render thread — especially for Vulkan / mobile rendering (like on the Pico 4).
You must ensure CreateView() is only ever called from the render thread.

In UE5.5 it works in editor but not in device. Theres no error when loading this xaml via widget

Hi,

Regarding the first issue, the callstack comes from a callback with the suffix _RenderThread. Could you share the whole callstack with us?

The missing xaml issue is indeed a bug. I'll give you a patch for that. Could you please create a ticket in our support portal for this issue?

Thank you.

Hi,
Thank you for your fast response. The xaml loading is only problematic on UE5.5. works fine on UE5.4
Crash when using Mobile Vulkan. Works fine on SM5

Also adding to viewport works and renders on 1 eye. Only have trouble rendering using NoesisWorldUI

Could you please provide the full call stack for this? It looks like this is coming from a _RenderThread() function, which should only be invoked from the render thread. This appears to be a bug in Unreal.
