covert a canvas_item type shader to a spatial type to be used on Quads in 3D

[rubenjavier]

This is not actually an issue but a request.
could you please convert at least one shader from canvas_item type to spatial type, to be used on a Quad mesh in 3D?
for example the fire shader to a spatial type, so it can be rendered on a Quad and the material then be set to billboard.

I think your shaders are great, but I would like to use them in 3D space also

Thanks in advance
best regards
