Mesh to Unity Terrain

[umbral wind]

Well... It seems to me that sampling it with raycasts is a good option

I have a data class holding the cells of the map though, including each cell's height

[sudden gyro]

Yeah why not - sounds kind of straightforward

[umbral wind]

sounds "easier" to generate the heightmap from that

[sudden gyro]

...compared to other options like rendering the height with an orthographic camera and custom shader

[umbral wind]

... map "altitude" ... 
        public long width;
        public long height;
        public Cell[] cells;
        public string version;

        public struct Cell {
            public Vector4 Heights;
            public byte type;
        }

[sudden gyro]

Oh wait you have cell data of the source map?

[umbral wind]

yes

[sudden gyro]

If it is any similiar to unity (grid based heights) you could try directly converting that first

Look at TerrainData.SetAlphamaps docs etc

[umbral wind]

I can show how it looks, 1sec.. let me boot unity

when we generate the meshes, unity complains about the verts amount so we had to split the ground into several pieces

project is open source though, if you'd like to take a look https://github.com/guilhermelhr/unityro and we load the ground at https://github.com/guilhermelhr/unityro/blob/develop/UnityClient/Assets/UnityRO.io/Loaders/GroundLoader.cs

[sudden gyro]

looks like you'll be able to convert it to unity terrain, at least geometry-wise

I guess iterate over cells

[umbral wind]

yea, gotta figure how to deal with the textures tho

[sudden gyro]

how is it stored?

[umbral wind]

atlas

[sudden gyro]

I mean how does it know where is grass, where is dirt etc

or is it just a pre-painted texture?

[umbral wind]

pre painted

[sudden gyro]

okay so its a sort of a tilemap

don't know the best way to transfer that to unity terrain, since it uses splatmaps to blend between textures

[umbral wind]

thank you for enlightening me

looks like this is going to the bottom of the backlog 😂

[sudden gyro]

these meshes look good though, what was the problem with mesh-generated terrain?

[umbral wind]

none, just wanted to see if it was feasible enough to give it a try and see if I could get some performance out of it
