Texture with optional normal and specular maps for use in 2D rendering. [CanvasTexture] is an alternative to [ImageTexture] for 2D rendering. It allows using normal maps and specular maps in any node that inherits from [CanvasItem]. [CanvasTexture] also allows overriding the texture's filter and repeat mode independently of the node's properties (or the project settings). [b]Note:[/b] [CanvasTexture] cannot be used in 3D. It will not display correctly when applied to any [VisualInstance3D], such as [Sprite3D] or [Decal]. For physically-based materials in 3D, use [BaseMaterial3D] instead. $DOCS_URL/tutorials/2d/2d_lights_and_shadows.html The diffuse (color) texture to use. This is the main texture you want to set in most cases. The normal map texture to use. Only has a visible effect if [Light2D]s are affecting this [CanvasTexture]. [b]Note:[/b] Godot expects the normal map to use X+, Y+, and Z+ coordinates. See [url=http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Common_Swizzle_Coordinates]this page[/url] for a comparison of normal map coordinates expected by popular engines. The multiplier for specular reflection colors. The [Light2D]'s color is also taken into account when determining the reflection color. Only has a visible effect if [Light2D]s are affecting this [CanvasTexture]. The specular exponent for [Light2D] specular reflections. Higher values result in a more glossy/"wet" look, with reflections becoming more localized and less visible overall. The default value of [code]1.0[/code] disables specular reflections entirely. Only has a visible effect if [Light2D]s are affecting this [CanvasTexture]. The specular map to use for [Light2D] specular reflections. This should be a grayscale or colored texture, with brighter areas resulting in a higher [member specular_shininess] value. Using a colored [member specular_texture] allows controlling specular shininess on a per-channel basis. Only has a visible effect if [Light2D]s are affecting this [CanvasTexture]. The texture filtering mode to use when drawing this [CanvasTexture]. The texture repeat mode to use when drawing this [CanvasTexture].
