Hey everyone,
I tried my best, but I can't figure out what the problem is.
I'm following the tutorial of Scott Benson (https://www.behance.net/gallery/1446492 ... alkthrough) to colorize cloned objects, using the Mograph Color Shader.
It turns out that the Mograph Color Shader itself is influenced by the document’s Input Color Profile, which is set to sRGB by default. The sRGB Color Profile doesn’t produce a linear black to white gradient, it operates on a curve (gamma). This more closely follows how the eye perceives color (and how screens display it), but it wreaks havoc when trying to use it to map evenly distributed things like what we’re trying to do.
In his file it works fine, but as soon as I copy it to my files, I'm unable to make it look right. All settings should be identical, but the menu has changed in C4D and even if the settings look the same, the result still does not at all:

Hi,
probably the scene was made with an old C4D version, so the colors are not matching.

Here is what happens if you add a Linear Field to the Formula Effector, with reverse X direction, and without changing the Color Mode:

Thanks Beppe!
Highly appreciated, your reliable feedback :!:

It's not a perfect solution though, the colors are washed out and you have to bother adjusting the other field.
I wonder if there is another solution for this? It's getting pretty complicated, I mean I just want the cloned objects to be colorized without shading in a comprehensible order. :(
