In a project I’m working on (mapbox ^^), I only set the projectionMatrix to control my Camera : scene.activeCamera.freezeProjectionMatrix(projectionMatrix); scene.render(true); So billboards does not work because camera.position = (0,0,0) For a specific mesh I can make : let invert = scene.activ…

Hi sharp, Sounds like a pretty interesting and unusual use case! Do you by any chance have a working sample you can share, ideally a Playground? There are a couple things that seem a little confusing to me which might be cleared up if I could see them in action. If you don’t have a working sample,…

Hi @syntheticmagus and thanks for taking the time to respond [image] syntheticmagus: canonical projection matrices cannot be generally inverted I use web mercator projection so it’s conformal and can be inverted. When I use a lookAt function on a mesh it works great ! [image] syntheticma…

A playground here would definitely help :slight_smile: we do not need the mapbox part just a couple planes highlighting your issue would be great.

Perhaps this is the same issue. [image] Babylon in Mapbox Layer Questions I make demo. The camera position is acquired at line 63 (console message), and it seems to be able to recognize the change in camera position. I think the problem is, as you say, that billboardMode …

It is the same issue, main problem is we can’t make a playground because the 3D context come from mapbox. To resolve the issue we need to explore the mapbox API and find a better way to reconstruct a babylon camera from the mapbox camera attributes.

The first place I asked my question is long, so I want to move it here. I make demo. Why doesn’t billbordmode work…? Babylon-mapbox billboard - JSFiddle - Code Playground Test your JavaScript, CSS, HTML or CoffeeScript online with JSFiddle code editor. fron…

Your demo isn’t working for me: [image]
