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 (1).
When clicked a new sidebar will appear with painting options(2).
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
blur tool : (shortcut - "3") in progress
fill tool : (shortcut - "4") use to fill the entire mesh with a color.
ADDITIONAL RESOURCES:
In VPainter/addons/vpainter/additional_resources/ you will find two shaders:
shader_vertex_color.shader - is 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 - is 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 and B channel contains the metal information.
* C: RGB color/albedo information.
* N: Normalmap information.
