| allowsAlphaSplit | Allow Alpha splitting on the imported texture when needed (for example ETC1 compression for textures with transparency). |
| cubemapConvolution | Convolution mode. |
| cubemapConvolutionExponent | Defines how fast Phong exponent wears off in mip maps. Higher value will apply less blur to high resolution mip maps. |
| cubemapConvolutionSteps | Defines how many different Phong exponents to store in mip maps. Higher value will give better transition between glossy and rough reflections, but will need higher texture resolution. |
| rgbm | RGBM encoding mode for HDR textures in TextureImporter. |
| spriteAlignment | Edge-relative alignment of the sprite graphic. |
| spriteBorder | Border sizes of the generated sprites. |
| spriteExtrude | The number of blank pixels to leave between the edge of the graphic and the mesh. |
| spriteMode | Sprite texture import mode. |
| spritePivot | Pivot point of the Sprite relative to its graphic's rectangle. |
| spritePixelsPerUnit | The number of pixels in the sprite that correspond to one unit in world space. |
| spriteTessellationDetail | The tessellation detail to be used for generating the mesh for the associated sprite if the SpriteMode is set to Single. For Multiple sprites, use the SpriteEditor to specify the value per sprite.
Valid values are in the range [0-1], with higher values generating a tighter mesh. A default of -1 will allow Unity to determine the value automatically. |
