Threshold at which the alpha scissor will discard values.
Threshold at which the alpha scissor will discard values. Higher values will result in more pixels being discarded. If the material becomes too opaque at a distance, try increasing [member alpha_scissor_threshold]. If the material disappears at a distance, try decreasing [member alpha_scissor_threshold].

<member name="anisotropy" type="float" setter="set_anisotropy" getter="get_anisotropy" default="0.0">
The strength of the anisotropy effect. This is multiplied by [member anisotropy_flowmap]'s alpha channel if a texture is defined there and the texture contains an alpha channel.
