P.S.: here is a Freeze 3D View Workflow - but as patch.
I have removed the save and load parts, as I think they are clear.

My best wishes for your project

Hi Bruce,

From the perspective where you can see the black artifacts, create a Freeze 3D View. The image in Photoshop should be limited to the problem area of the fix (e.g., Stamp Tool). Leave only the PP Layer in the file, while the layer hols strictly transparency and only in the area of the problem content.

Save it, merge it apply it. The black seam might come from the Black background that the "PP All Layer" had, which should not be part of the Merge file.

Is that working for you?

Cheers

Thank you, Pim.

I deeply love to do that! Supporting many projects and productions and answering questions of any kind. I am the one who has to say thank you, as it allowed me to grow and get involved in so many ideas and creative projects.

Your project so far has been colorful in many ways; it's fun to see that growing.

Enjoy!

Thank you, Pim,

Yes, I'm ready to slow down for 9 days, as I was searching for an Object. It would have clicked with Particle Blend Modifier.

Even the Documentation's URL has an Object in the title,
But I was searching in the Redshift Documentation based on all the Nodes questions and color questions. Sorry about that, my fault.

Here is the Manual page, which I think has a lot to offer:

Thanks for your patience! I will check in next week, but I try to keep it short; typically, that is the slowest week of the year, hence my timing.

Enjoy

No problem, hard to tell sometimes, Pim.

The readability is easier for anyone when follow-ups are in a new thread, as they might come back to the initial question. Sometimes it is one combined them, sometimes not. Separating makes it also easier to link to it.

It is not a pleasure to bother you with that. So: Sorry. But I know how often I have gotten feedback about the noisy threads in the first years of the 21+ years I've been supporting Cinema 4D fora.

Enjoy your weekend

Hi Bruce,

Thanks for the reply,
Sorry, I can't reproduce the black artifact. Some wild guesses...

Can you reduce the PSD file to the PP layer, drag it out of the Folder then delete the Folder with the mask?

Perhaps setting the Freezing 3D View to 2x of 4x (scale) might limit the effect.

Also, for the "PP All Layers", try to delete it before saving the PSD. Is that helping?

All the best

Hi Pim,

Mixing Color in your setup is like layering "Gels". With this, the first one works like a filter. For example, if you have a red filter and a cyan (second) filter, they will block light simply based on frequencies.
However, what is a pure green and a Pure red? If you use an sRGB colorspace, you get something, but not a full saturated color like green or red. Yes, I know, everyone will say, but I can see it on my screen. Well, typically not. Which is a longer story. But a pure red in sRGB is in sRGB 8/bit values 255; 0; 0, but that is the smallest colorspace possible and never should be used in professional pipelines. This means if I take these 8/bit values, the red in ACES 2065-1 would be 112; 23; 4. This means not even a fraction of that saturation that the sRGB or even P3 screen shows. So, a red would not block green fully as it has green in it. So, mixing colors is a little bit more complex. (So, using ACES 2065-1 all the way, well, yes and no. Typically, a standard screen can't handle the colors, some Applications have problems (hence the ACEScg limitations), and the need for Gamut Compression and, later on, Ton-mapping changes the colors to fit into a smaller space, that many people answer with creative (to say it kindly) workarounds. In other words, it is a theme that takes a longer time to dive fully into it. I can share some book tips, or (my favorite) as I'm an Alumni of the Color Academy for professional Colorists, Los Angeles, to invest a year in their program.

But well, if the light goes through those, and both have perhaps a white background, the light would be a colorful ( or less so) shadow. In any way, this shadow moves back through both filters and is affected again. Like every color filter is just a partial ND filter. Note: colors are not real; we produce them inside of our brain. Light has only frequencies, which different cones can receive more or less, and then Color is created later. In terms of filter, some frequencies get more or less blocked, others don't. Why do I explain all of that? Because feeding Color into the Opacity means to create a filter. While red will create a Cyan-looking result. Think of the red channel, if red it the color resulting from RGB as a channel that shows white. Hence Blue and Green are black, resulting in Cyan as transparency. If inverted only red is a black channel, and the result looks like red gel filter.

In your scene, there is the top layer set to be a filter, and using the colors to drive the Opacity means the red is more transparent. I would suggest here a neutral gray, perhaps 70%. If the colors have to drive this, use an Invert to get the proper colors of the '70s.

Tip: Enabling the View - Options> HQ Noise might help to get improved previews (not related to the Color question)

In short, that was a deep dive for that short question, but I wanted to share more insights into what is going on - instead of just dumping a file and telling you to do this. Which I find always for those themes not adequate. Read it and let it sit for a while; it is not a small subject.

Here is your file back

Hi Pim,

There is, to my knowledge, no Blend Object.

Blend Modes: like in Photoshop

Please share the exact name, and I will do my best to share the information.

Hi Pim,

The Vertex Attribute Node takes the Vertex Map, either single channel or Color/alpha from the object. The key concept here is that every point of the object has an ID number; the tag then adds a single value (0-1) to it, or for the Color, even a four-channel value RGB-A. The colors or value of the Vertex maps can be painted or applied with Fields and other options. The Vertex Tag should always get a proper name. Leaving it by default can cause confusion, leading to unwanted results.

The Vertex Attribute Node takes those Point/Vertices values in and interpolates those over the surface. The lower the number of points, the less likely a pleasing result can be expected. Higher values might slow down the processing. Sometimes, baking the data can be beneficial.

The result is, to a certain degree, comparable between a shader and a texture and can be used to drive channels in the materials.

To know which Vertex Tag to use, the Node has an entry field for the name; dragging the tag into will work.

One key feature when using these for anything is that values should be provided in the way they are needed. In short, RGB is not always RGB, which sounds cryptic, but Linear and gamma-encoded values deliver a completely different result if interpreted wrongly.
Color Management is often ignored for these values, and the results might look surprising.

Hi Pim,

Please continue with the new Question in the thread linked above. Thank you.
