I am talking about using a texture atlas to PACK the terrain layer textures into a texture atlas and maintain each texture’s rectangle (0 to 1) in the atlas so i can pack all the terrain layer textures (up to 12) into one single texture and NOT have to main a separate texture slot properties on the material for each supported texture: material.terrainTexture1īut instead do something like: material.terrainTextureAtlasĪnd then using the maintained rects as shader vec4 for each:

Wow bro … Now thats some shader code (I dont understand it all :))īut hey man, i think we might be talking about Texture Atlas usage for two very different things. Texture2DLODExt not blur any part and if we calculate the distance and set to LOD parameter That work fine but the new problem happen in far place Then the sides image content be effect the main atlas part in blur ed imageĪnd solution : ' i need test it after this week ' You probably want to enable at least trilinear filtering for your textures, or maybe anisotropic filtering.The main problem is happen when “texture2D” blur your texture in far places I wrote an article that goes into the visual differences between bilinear, trilinear, and anisotropic filtering just what bilinear filtering looks like. On PC you can slide that Aniso Level all the way to 16 on every texture in the game and you'd be hard pressed to notice a difference on even the slowest integrated GPUs. On mobile anisotropic filtering can be quite expensive, potentially dropping your frame rate in half or worse at the higher values, and still being a potentially large hit at lower values if those textures cover a large part of the screen. This will force any texture not set to Filter Mode > Point and using an Aniso Level of 1 to 9 effectively use an Aniso Level of 9. Or you can go to your project's Quality settings and change Anisotropic Textures to Forced On. You can manually override textures to use Trilinear, or you can set the Aniso Level to something other than 0 or 1. You probably want to enable at least trilinear filtering for your textures, or maybe anisotropic filtering.īy default all textures are set to use Filter Mode > Bilinear.

That's just what bilinear filtering looks like.
