- Mention the Use Nearest Mipmap Filter project setting. - Fix nearest mipmap claiming to always use bilinear filtering (it uses trilinear filtering by default, like linear mipmap).

<constant name="TYPE_DATA" value="0" enum="TextureType">
|
|
No hints are added to the uniform declaration.

<constant name="TYPE_COLOR" value="1" enum="TextureType">
|

Adds [code]source_color[/code] as hint to the uniform declaration for proper sRGB to linear conversion.
|
|
</constant>
|
|
<constant name="TYPE_NORMAL_MAP" value="2" enum="TextureType">
|
|
Adds [code]hint_normal[/code] as hint to the uniform declaration, which internally converts the texture for proper usage as normal map.
|
|
</constant>
|
|
<constant name="TYPE_ANISOTROPY" value="3" enum="TextureType">
|
|
Adds [code]hint_anisotropy[/code] as hint to the uniform declaration to use for a flowmap.

<constant name="TYPE_MAX" value="4" enum="TextureType">

Represents the size of the [enum TextureType] enum.

Defaults to fully opaque white color.

Defaults to fully opaque black color.

<constant name="FILTER_DEFAULT" value="0" enum="TextureFilter">
|
|
Sample the texture using the filter determined by the node this shader is attached to.
|
|
</constant>
|
|
<constant name="FILTER_NEAREST" value="1" enum="TextureFilter">
|
|
The texture filter reads from the nearest pixel only. This makes the texture look pixelated from up close, and grainy from a distance (due to mipmaps not being sampled).
|
|
</constant>
|
|
<constant name="FILTER_LINEAR" value="2" enum="TextureFilter">
|
|
The texture filter blends between the nearest 4 pixels. This makes the texture look smooth from up close, and grainy from a distance (due to mipmaps not being sampled).
|
|
</constant>
|
|
<constant name="FILTER_NEAREST_MIPMAP" value="3" enum="TextureFilter">
|
|
The texture filter reads from the nearest pixel and blends between the nearest 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is [code]true[/code]). This makes the texture look pixelated from up close, and smooth from a distance.
|
|
Use this for non-pixel art textures that may be viewed at a low scale (e.g. due to [Camera2D] zoom or sprite scaling), as mipmaps are important to smooth out pixels that are smaller than on-screen pixels.
|
|
</constant>
|
|
<constant name="FILTER_LINEAR_MIPMAP" value="4" enum="TextureFilter">
|
|
The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is [code]true[/code]). This makes the texture look smooth from up close, and smooth from a distance.

|
|
</constant>
|
|
<constant name="FILTER_NEAREST_MIPMAP_ANISOTROPIC" value="5" enum="TextureFilter">
|
|
The texture filter reads from the nearest pixel and blends between 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is [code]true[/code]) based on the angle between the surface and the camera view. This makes the texture look pixelated from up close, and smooth from a distance. Anisotropic filtering improves texture quality on surfaces that are almost in line with the camera, but is slightly slower. The anisotropic filtering level can be changed by adjusting [member ProjectSettings.rendering/textures/default_filters/anisotropic_filtering_level].
|
|
[b]Note:[/b] This texture filter is rarely useful in 2D projects. [constant FILTER_NEAREST_MIPMAP] is usually more appropriate in this case.

</constant>

<constant name="FILTER_LINEAR_MIPMAP_ANISOTROPIC" value="6" enum="TextureFilter">
|

The texture filter blends between the nearest 4 pixels and blends between 2 mipmaps (or uses the nearest mipmap if [member ProjectSettings.rendering/textures/default_filters/use_nearest_mipmap_filter] is [code]true[/code]) based on the angle between the surface and the camera view.
