@Zylann First and foremost I want to say I love your terrain plugin. I have spent the last couple of days working on improving it to do a vertex paint mode. I'm currently a bit stuck and I think you are probably the only person in the world who can actually help.
Modifying the menu to have a a vertex button and a dropper tool was the easy part:
The reason I am doing this is because last year I was halfway through developing my very own game using the blender game engine and switched to the Uchronia blender fork. During my development I stumbled across a way of using vertex colors to map seemeless terrain types. I was previously told it was only possible to seemlessly blend 4 terrain types, by using combinations of sin and cosine nodes I have managed to do 8, now 9 thanks to makign use of normals similiar to how your terrain engine has green and brown tiles. So if there is a slope it does this rocky texture.
As you can see from when I hooked up vertex color to diffuse this is what the terrain actually looks like just to further verify I am not lying or have cheated this process in any way shape or form:
Here is how I linked up the nodes in the shader graph mode:
I have found a way to change vertex colors within your terrain editor albeit crudely from code directly in the "_generate_mesh_at" function in terrain.gd using the lines of code:
var meshData = MeshDataTool.new()
var vertexindex = meshData.get_vertex_count()
var vertexcolor = Color(0.0, 0.0, 1.0)
for i in range(0,vertexindex):
This sets the terrain to Blue ( like you didn't know that already! )
I've tried to rewrite the entire data structure from 2D arrays to 3D arrays.
Your previous structure had grid[x][y] which would return a vector3 if I'm not mistaken. I'm trying to rewrite it so that it can store grid[x][y][z] where z has 5 var's [x][y] is the vector3, 1 2 3 4 are going to be red green blue and alpha floats.
Anyway I've spent a long time trying to rewrite the code adding lots of 's trying to trace the code back and I'm now really stuck and lost. I would really appreciate your help
Here's one of the error messages:
I have some code pastes of the work in progress I have done

Please obi wan kenobi you are my only hope
Greetings. I wanted to ask if Git master is compatible with the upcoming Godot 4.0. If not is there a deadline as to when a working version will exist? I'm very eager to switch go the new Godot once it's out but unsure if this plugin will stop working and put the project I'm using it for on hold in terms of upgrading. Thank you.
The plugin does not work with Godot 4.0 yet, because that version of Godot is not ready for production. I will start working on that when it reaches beta stage, most likely.
