`InLayerColor` is the color you used to paint on the layer with the brush (this allows the material to generate differently based on the brush color); it is not the color present on the material itself or on underlying components. If you need the color from underlying layers, use `InLowerLayer`; if you need the color from underlying components, use `InColorProperty`.

No luck, how can i assign a filter to current Painted layer w/material ?

more... can I add more that one filter to any Layer ?

[Carlosan]

so Curves Visualization = hidden ?

on Layer Panel, eye icon = Switch layer visibility

on Node Inspector = This eye is used to hide or show parameters in the object inspector. Click on the eye to hide the parameter in the object inspector.

 

user result = confusing

eye is used for hide/unhide, dont matter the context. To keep the same procedure will be helpful

[Carlosan]

sorry but... where are this controls ?

Use Frame / Group: To avoid getting lost in a large graph, select blocks of nodes and create a `Frame`. Give it a clear name (e.g., “Base Color” or “Rust Normals”) and a color.

Monitor speed (Profiler): All nodes run on the GPU, but excessive use of dozens of real-time noise generators can slow down the preview on weaker graphics cards. Use Baking to fix complex sections of the graph.

On Modifiers we can find Color Category (UserPrefs\NodeGraphs\NGModifiers)

But NGModifiers (Node Graph Modifiers) is a preset window intended for procedural effects that affect the shape or geometry of a model. In the code, they are often called “Deformers”.

 

location is right... or is it a Filter ? NodeGraphs\NGFilters

[Carlosan]

Source Type = Layer or Object

differences ?

Select **Object** if you want to work with the selected sculpt object; select **Layer** if you want to work with the selected PPP (Per-pixel painting) layer.

You're right, I'll move them to Filters.

This is the Profiler.


I’ve removed Frame/Group from the documentation; there’s a different approach now—inline nodes are used—and I’ll update the documentation soon.

I liked the initial Group idea, if it is possible to convert any group to SubGraph (Filters like example) it will be time saver.

sorry i was not clear, my question was about Baking. Do you refer to Bake on Retopo Room or where ?

Yes, you can add an unlimited number of components to the Object Inspector and assign a separate NodeGraph to each one.

We’ll think about what to replace this eye icon with.

Sorry... I am a little slow on this

Can filters be applied to the same layer ? 
or must be added on another layer ? 

works as adjustment layers on Photoshop ?

If yes, can be applied only to a Paint Layers Group ?
or it is applied globally ?

This tool bakes changes made by nodes on sculpting objects onto the vertices of the sculpting objects.

Yes, you can apply multiple filters to a single layer; to do this, create several "Material" components in the Object Inspector (since filters operate on material properties) and assign a specific filter to each one. Note that if you haven't painted anything on the layer with a brush, you need to select a mask for the filter to apply to, create an "OutMask" node, or click the "Toggle visibility of the mask" button to apply the changes to the entire layer.

It would be great to add the NG category to the Library.

And to add more free Node packs monthly.
