Hi ive been working on a Voxel terrian generator for some time now and its nearing the end of it all, bit ive come across something weird and not entirely sure how to fix it as you can see by the image below am getting seams between each voxel, each voxel is 1x1x1 and placed right next to each other, I know it has something to do with my Atlas am using and ive played with it for hours but to no result, so am here to ask for help…
– Current Results
–My Atlas Function
public Texture2D CreateAtlas()
{
string[] _Images = System.IO.Directory.GetFiles("Textures/");
//Debug.Log("Loaded " + (_Images.Length - 1) + " Textures");
int pixelwidth = 128;
int pixelheight = 128;
int AtlasWidth = Mathf.CeilToInt((Mathf.Sqrt(_Images.Length) + 2) * pixelwidth);
int AtlasHeight = Mathf.CeilToInt((Mathf.Sqrt(_Images.Length) + 2) * pixelheight);
//Debug.Log(AtlasWidth + "," + AtlasHeight);
Texture2D Atlas = new Texture2D(AtlasWidth, AtlasHeight);
int count = 0;
for (int x = 0; x < AtlasWidth / pixelwidth; x++)
{
for (int y = 0; y < AtlasHeight / pixelheight; y++)
{
if (count >= _Images.Length - 1)
{
goto end;
}
Texture2D temp = new Texture2D(0, 0);
temp.LoadImage(System.IO.File.ReadAllBytes(_Images[count]));
Atlas.SetPixels(x * pixelwidth, y * pixelheight, pixelwidth, pixelheight, temp.GetPixels());
float startx = x * pixelwidth;
float starty = y * pixelheight;
float perpixelratiox = 1 / (float)Atlas.width;
float perpixelratioy = 1 / (float)Atlas.height;
startx *= perpixelratiox;
starty *= perpixelratioy;
float endx = startx + (perpixelratiox * pixelwidth);
float endy = starty + (perpixelratioy * pixelheight);
UVMap.AddNewMap(_Images[count], new Vector2[]
{
new Vector2(startx,starty),
new Vector2(startx,endy),
new Vector2(endx,starty),
new Vector2(endx,endy)
});
count++;
}
}
end:;
Texture2D SavedAtlas = new Texture2D(0, 0);
SavedAtlas.LoadImage(Atlas.EncodeToPNG());
SavedAtlas.wrapMode = TextureWrapMode.Clamp;
SavedAtlas.filterMode = FilterMode.Point;
return SavedAtlas;
}

–and the atlas it create
And yes i know its minecraft, but its all the textures i had on hand XD
Ive tried turning off AA, changed anisotropic Textures all the stuff its said on Google… am just completly outta ideas now…
