I don’t know why this would affect ornament sales. I like ornaments because they change the shape and details, not because they change the color. I would still buy an ornament and happily apply a shader to it if we were able.
That’s fine though, in that case it turns it into a metallic texture that you can’t get otherwise, even through shaders. So if someone wants that chrome effect, they’ll get the ornament.
I would understand the whole shader argument if they were consistent and you couldn’t apply shaders to any exotic gear. But in this case, you can do one, but you can’t do the other, which makes the whole thing seem a little arbitrary.
