I fail to see you conclusion here. In RL I do – among other things – program software synthesizers, and trust me, the major work is sliders and knobs; to get them right. Only when there’s sound-samples involved, there’s this element that resembles a texture in EEP (something from the “outside”, the second element). The results of such programming, call it slider & knob play, is often sold at prices that not everyone wishes to pay – or can pay. However, they’re sold indeed. Because it’s people who knows their way around this, that sells them.
WL/EEP is the same, though there’s likely little interest in this in the big RL. All the timeconsuming adjustments in order to get a sky right; not to mention a day-cycle … Give away??! That part of the work is more than the frame of a painting, as you merely suggest. There’s loads of free inspiration in the old WL libraries in everyone’s inventory to provide more than a fundament for free WL/EEP inspiration and learning.
So if it should be sellable at fair prices, you don’t give the sliders away. They’re like brushstrokes to the painter.
When it’s set to no-modify, it should react like when it’s ditto scripts in an object:
Hidden.
