To open and test included .blend file please use Blender version 2.80.
However, to use the Carvature node or any selected materials you can use earlier version of Blender as well (tested on 2.79 and 2.80).
To add Carvature to your project:
- File → Append (Shift+F1).
- Navigate and select Carvature.blend.
- a) Select NodeTree → Carvature if you want to build your pattern from scratch,
b) select Materials → any included material if you prefer to use a prepared material.
- Use Node Editor (2.79) or Shader Editor (2.80) to create or modify a material.
Once you opened your new file, please follow the description below to fully understand how it works.
Some of the paragraphs are intentionally omitted to avoid repetiveness, some of them are just self-explanatory.
The texture by default is based on the object's Z-Axis, which is surrounded by growth rings infinitely.
Ring (growth ring, annual ring) - a layer of wood formed during one growing season
Latewood (summer wood) - darker part of ring formed during late part of growing season
Earlywood (spring wood) - lighter part of ring formed during early part of growing season
Heartwood - dead, central part of wood, usually darker color
Stretch deformation along the z-axis.
Interpolation between Color1 and Color2
Latewood coverage across the ring.
Diameter of latewood cells - higher scale means smaller diameter.
Type of rays projection within texture. In real life rays come out from center outside (value 1), but for CG purpose there is an option to show just surface part of 'ray' (value 0).
Density of rays. Higher scale means more dense, but smaller rays.
Coverage or size of rays.
General texture bumpiness strength. By default darker areas mean lower height.
The density of knots, keep in mind the higher density decreases knots' size.
Diameter of knots.
Density of rings within knot.
Knots Env Size
Knots Envelope Size - area around the knot. Value 2 means the envelope size is about 2 times higher than knot size.
Knots Env Depth
Knots Envelope Depth - area around the knot. Value 0.5 means the density of rings within envelope is about 2 times lower than within knot.
Value 0 means round knots, value 1 means maximum deformation.
Infinite Z-Offset. Use the slider to find perfect pattern.
For multiple objects using same mesh, plug the Object Info's Random value to add variety (example in the Chess scene).
Divide texture along x-axis (example in Board scene).
Value 0 - slicing disabled.
Value 1 - slices are 2 units wide (main panel starts on x = -1 and ends on x = 1)
Add variety to created slices (example in Board scene).
Value 0 - all slices look the same.
Value 1 - every next slice is moved 1 slice width value.
R - Latewood
G - Earlywood
B - Rays
Value 0 - dot size.
Value 1 - infinite length.
Texture Coordinate input.
The most commonly used coordinate is Object, but other options are also possible depending on the user's needs, however, some Mapping Node adjustments may be necessary.
Color output to your shader.
Knots factor. Use with Color Ramp node and mix with Color output to make knots darker (example in Pallet scene).
Normal output to your shader.
Texture coordinates including Scale, Slices and Offset. Plug into additional textures for more accurate blending with Carvature texture.
