No Procedural mesh with HTML5


I’m having difficulties getting procedural meshes to work with HTML5. To try to debug I have created a first-person project and added a BP with a single procedural mesh box. When playing the game regularly this mesh is visible (image 1). When playing on HTML5 the procedural mesh is not visible (image 2).

The issue doesn’t seem to be visibility, but rather the fact that the BP and procedural mesh cant be accessed on HTML5. I’ve added an image of the BP (image 3) and of the console log for clarity (image 4). What is happening and how can I fix it?
