Blender 3.2 can also be painted in Sculpt Mode! Distortion tools are also available – Blender Watching

In this series, we will tell you how to use the free high-performance 3D modeling tool “Blender” and related information.

June 8 (GMT), “Blender 3.2” officially releasedThis was done. This time, I would like to introduce the redesigned “Color Theme” function.

What is the color characteristic?

The “color theme” is the so-called “head color” in the past and other application software. It holds the color information for each vertex and is displayed by interpolating between each vertex.

In “Blender” it is as easy as coloring in mode[Vertex Paint]And add a “color theme” (the previous header color).

There is no need to create a “texture image” or “UV develop”, and the processing is light, so it is a convenient function for quick coloring.

Coloring by color theme (head color) and shading node

Let’s see what has really changed.

Expand data format

In the past, it was just “RGB(A)” 32 bytes “color byte”, but now you can use the high precision “floating point number precision color” (setting name is color).

You can also specify “Vertex” and “Face Corner” (the traditional method) as the storage location (domain). The difference between the two is whether it can be drawn exactly on the surface as shown in the figure below.

Differences in behavior depending on the field settings. “Red” for both vertices is set in the center, but in[Vertex]is interpolated with “black” below and cannot be drawn separately.

These data formats can be selected when adding in a list[خصائص بيانات الكائن]-[سمات اللون].

If a ‘low poly model’ with a small number of faces is likely to require color coding as shown on the right side of the image above, a ‘vertex’ can be used to reduce the amount of data in a high poly model such as a ‘corner face’ and a ‘sculpt model’. described later. It seems appropriate. The default setting is “Vertex” for[المجال]and “color” for[نوع البيانات].

Adjust dialog when adding color themes

Also, if you enter a mode[Vertex Paint]And paint without creating a color theme, the color theme data will be automatically added as “color” (when using Japanese UI). In this case, be[المجال]is “Face Corner” and[Data Type]It is “Byte Color”.

In the menu, “Byte Color” is displayed as “Byte Color”, “Floating Point Precision Color” is simply displayed as “Color”, “Vertex” is displayed as “Vertex”, and “Face Corner” is displayed as Corner face.

Unfortunately, it appears that the function to convert to each other is not implemented at the moment.

Ease of access from engineering nodes

You can now easily access and operate a Geometry node through a node[Named Attribute]knot[Named Attribute Storage]. As shown in the figure below, it is possible to read, manipulate and write specific color attributes.

Drawing is possible from sculpting mode

This color theme has a drawback that it has to be broken into pieces as necessary to add a good style as it is colorful for each head.

However, to put it the other way around, it can be said that it is compatible with the subdivided “sculpting model” (with many vertices). In “v3.2” you can plot the vertices in[وضع النحت].

It also supports mask functions such as[Box Mask]Existing sculpting tools such as[Surface Set].

However, at this time, it cannot be used with tools that change precision, such as[Dyntopo](Dynamic Structure) and “Multiple Precision”.

Brushes included in the demo file and their respective samples

Especially the “Spatter” brush in the demo file was very useful, and even the title picture was useful for getting the legs and wings dirty. You can copy to your file by selecting[قائمة الملف]-[إلحاق]-[فرشاة]-[ترشيش].

The figure below is a screenshot of the working screen. By the way, the color attribute of the spot is created separately from the color attribute of the coloration, and the two are combined together and used in the shading node. By the way, the fuzzy light on the tip of the wing seems to be because the front and back are stuck together, but that’s interesting so I photographed it as it is.
