The issue I think is many aircraft could be changed to do something simpler (use decal text with no lighting), or use Canvas, but masking a fully generic replacement for what <text> used to do is quite difficult - for correctness it should use the full lighting model / ALS / etc so that painted text on a panel / tail / etc is lit correctly.

That’s completely doable but means hooking an effect into the <text> element, which is certainly some work to get correct, since the shader also needs to interact correctly with the osgText source texture (containing the glyphs and offsets)

Kind regards,
James
