TextureArray

Inherits: TextureLayered < Resource < Reference < Object

Array of textures stored in a single primitive.

Description

TextureArrays store an array of Images in a single Texture primitive. Each layer of the texture array has its own mipmap chain. This makes it is a good alternative to texture atlases.

TextureArrays must be displayed using shaders. After importing your file as a TextureArray and setting the appropriate Horizontal and Vertical Slices, display it by setting it as a uniform to a shader, for example:

shader_type canvas_item;

uniform sampler2DArray tex;
uniform int index;

void fragment() {
    COLOR = texture(tex, vec3(UV.x, UV.y, float(index)));
}

Set the integer uniform "index" to show a particular part of the texture as defined by the Horizontal and Vertical Slices in the importer.
