THE BRANCH FOR 4.X is STILL A WORK IN PROGRESS AND NOT WORKING!!!

A vertex painting addon for the Godot game engine.

DOWNLOAD AND INSTALL:

Download the addon from https://github.com/tomankirilov/VPainter. Copy the addons folder in your project directory.
In Project/Project Settings/Plugins set VPainter to Active.

CHANGE LOG:

v0.2:

  • Added support for pressure sensitive pen tablets.
  • Some small bug fixes.

USING THE PLUGIN:


In the 3d editor when a MeshInstance node with a valid mesh resource is selected an icon will appear in the top editor menu.
When clicked a new sidebar will appear with painting options.

TOOLS:


brush tool : (Shortcut - "1") use to paint vertex colors. You can adjust the size with the sliders or by using "[" and "]"
picker tool: (Shortcut - "2") use to pick the vertex color under the mouse cursor when clicked.
blur tool : (shortcut - "3") in progress
fill tool : (shortcut - "4") use to fill the entire mesh with a color. Fill tool is affected by the opacity and blend mode.

color swatches: There are two color swatches. in the main panel. When clicked they reveal a color picker dialog. The last one clicked is the active one.

pressure sensitivity: There is a new option for pressure sensitive pen tablets.

  • SizePressure - the size of your brush depends on the pressure input.
  • OpacityPressure - the opacity of your brush depends on the pressure input.

blending modes: There are currently 5 blending modes supported:

  • MIX: linearly interpolated between the colors.
  • ADD: adds the colors.
  • SUBTRACT: subtracts the colors.
  • MULTIPLY: multiplies the colors.
  • DIVIDE: divides the colors.

size: controls the size of the brush and blur tool.
opacity: controls the opacity of the brush and fill tool.
hardness: controls the hardness of the brush and blur tool.
spacing : controls the spacing between the brush "dabs". Lower spacing results in a more precise line.

make local copy : makes a local copy of the mesh. It is useful if you don't want to overwrite your original mesh data.

LIMITATIONS:

  • Currently Vpainter does not support godot's primitive meshes. It only works with imported meshes.
  • Currently only RGB painting is supported. Alpha channel painting is in the works.
  • Currently Vpainter does not support meshes with multiple instances of floating geometry.

ADDITIONAL RESOURCES:

In VPainter/addons/vpainter/additional_resources/ you will find two shaders:

  • shader_vertex_color.shader:
    A simple shader that displays the vertex color. It has the possibility to isolate R, G and B channels so you can preview them individually.
  • height_blend_4_textures.shader:
    A shader used in the first presentation. It is used for mixing 4 textures based on a heightmap and vertex color.
    The shader uses 3 textures per material:
    • M: A mask texture.
      R channel contains the height information
      G channel contains the rougness information
      B channel contains the metal information.
    • C: RGB color/albedo information.
    • N: Normalmap information.
