You’re very welcome, Anunciada, thanks for the reply.
I see that you have explored this file carefully, thank you very much for that!
With the solid first, I introduced the value (the sine curve), and the Shader is then pure color (the color clover). It was more to make a point, please have a look at the file below, it will also work with just one Layer.
The Cloner introduces a Clone Color. Move the color to get white and have an eye on the Clones. They turn into a pastel, then more or less into a faded color, if at all color is left. So, what happens? The Effector> Parameter Color Settings are typically set to Add. Which means that the color that is provided from this Effector will be added to the current Clone Color. If the Cloner Object is set to black, anything you add to it from a single Effector, with show up on the clones as expected. In numbers: black equals zero, any color is above zero, if added, zero plus value = value. Colors are expressed in RGB, so: 0,0,0 + 255, 127, 0 = 255, 127, 0 (Orange)
You can easily see where it would go with the other settings, like subtract, etc.
Where to learn all of that?
Since we have fields, I hesitate to share none-field based tutorials, but allow me to give you this link to start with:
You might wonder if I missed your question. It looks that way. The most confusion that I noticed over the past 13 years with the shader effector is based (as mentioned above) that the Shader Effector can take images in, but it supplies only a single color value to each clone. No image. Images are used here as information. As in the little math I showed above, values can be combined, or at least calculated with something to get an effect. Images are a relatively intuitive source to create such information (data, information). Keep this in mind when you explore: What information is given at which point, and how is the flow of that information. This is not something one can learn for all possible combinations, which means, it will be an exploration for each new scene.
If you have a question about a different tutorial, please open a new thread with the HELP button below the tutorial, so other arts can find it.
In case there is a question that is only remotely related to a tutorial, please use the Q&A forum.
Either way, I’m happy to look into it. If there is any chance that you can share the time (as in 12:34 min: sec) where something has hit your interest, please do so, thanks!
Enjoy the exploration
