[TextureArray]s store an array of [Image]s 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.
|
|
[TextureArray]s 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:
|
|
[codeblock]
|
|
shader_type canvas_item;
|
|
|
|
uniform sampler2DArray tex;
|
|
uniform int index;
|
|
|
|
void fragment() {
|
|
COLOR = texture(tex, vec3(UV.x, UV.y, float(index)));
|
|
}
|
|
[/codeblock]
|
|
Set the integer uniform "index" to show a particular part of the texture as defined by the Horizontal and Vertical Slices in the importer.
