That’s it for pixel art as textures for 3D models. It heavily depends on the number of colors used to create the pixel art image, this way, it’s up to the reader to test the 16 bit color formats.ĭon’t use the DXT1 or the DXT5 compressed formats: they will cause the pixels to get blended together. Pixel art images tend not to have a lot of different shades of the same color, meaning that, in some cases the RGB 16 bit or the RGBA 16 bit formats could be used, however, they might alter the color of the image. If that’s not your case, you must set it as RGBA 32 bit. In this case, it’s set to RGB 24 bit, because the transparency information at the Alpha channel was not needed (for this example). The latter (Texture Format) defines how the image gets decoded by the engine. Since the image file used in this tutorial is 64×64, we just select 64 from the drop down menu. The former refers to the maximum size an imported texture can have in Unity. The distortion will be even worse when the mip map is being used and angle between the camera and the 3D object is too steep.įinally, there is the Max Size and the Texture Format Settings. To exemplify, here’s an image that shows the difference between a properly scaled pixel art image and one that isn’t:īy enabling the mip map generation, the pixel art will look blurred when the 3D object is distant from the camera. So, by following those two simple rules, the reader can rest assured that the image will be rendered as intended. By doing this, we will be making sure that the Texture Importer in Unity doesn’t change the image’s pixel information in any way, since images which are not power of two are resized in the engine to meet this criteria. While at it, the pixel art image must be exported as a square with its sides having a size equal to any number that is a power of two. So, this post covers how the different Texture Importer settings affects the pixel art textures in 3D models and in the game’s graphical user interface (GUI).īefore importing the images into the aforementioned game engine, they have to be correctly prepared at an image editing software, like Photoshop or GIMP. This Unity post explains how to prepare images and set the Texture Importer settings to correctly render pixel art in Unit圓D.
