Hello, no_shadow keyword seems intended for object blocks,  is there anything
similar at the texture or finish level?
I am searching for a way to emulate Blender materials "shadeless" option.

No, nothing like that at present.

You'd have to track down what objects use such a "shadeless" material,
and give those objects the "no_shadow" flag.


Adding such a feature to textures would generally be possible, but a few
questions would have to be answered first; for example: How should a
refractive material with that property interact with photons? How should
it interact in a stack of layered textures?

The easiest-to-implement solution would probably be to just force the
pigment to rgbt 1 for the sake of shadows (which would also have to
include photons); in that case it would best be made a pigment property.

On the other hand that would still leave photons interacting with the
material, such as being refracted and possibly reflected, which may not
be intended.
