![]() Prefer Sharp Filteringīy default Redshift will attempt to bias texture filtering to produce the sharpest results. This produces much softer looking textures than regular bilinear filtering, but at the expense of slower rendering. Bicubic FilteringĮnables bicubic filtering on textures that are magnified. So, setting the ‘Filter Enable’ option to ‘None’ is recommended to remove any undesired artifacts due to filtering. When this is the case, filtering and MIP-mapping will result in ‘in-between’ values that might not make sense for the rotation texture to function properly. ![]() If correcting your texture in this kind of situation is not an option, then it is recommended you change the ‘Filter Enable’ property to ‘Magnification’, so you still get soft, filtered results when magnifying the texture, but no filtering and thus bleeding when ‘minifying’ the texture.īelow is an example of a poorly configured texture and a correctly configured texture:Īnother situation when you might need to disable filtering is when a texture contains non-color information, such as rotation, which could be used to drive the anisotropy rotation of reflection. When this is the case, filtering and MIP-mapping will result in undesirable color bleeding artifacts that can manifest as a halo around the cut-out texture. Sometimes a texture may require special filtering treatment, where the global texture sampling mode (found under the Optimization tab) might not be adequate.įor example, this can be the case when a texture has an alpha cut-out and the color part of the texture is not configured to take texture filtering into consideration. ![]() Magnification/Minification ( recommended default.Magnification ( no MIP-mapping, point-sampled for ‘minification’).None ( no MIP-mapping, point-sampled for ‘minification’ and ‘magnification’).Selects the filtering enable mode of the texture sampler
