As title say - I have a CSS3DRenderer in my scene, but I would like to use its render output as a texture. Is this even possible? I looked at the renderer’s source and the situation doesn’t look too good as all it does is manipulating DOM object’s transforms, but thought I’d ask here about any technique I’m not aware of…
No, this is not possible since
CSS3DRenderer since the renderer works with plain DOM elements and CSS (which is technically decoupled from WebGL).
