Unity extract asset to picture5/29/2024 ![]() Extracting Assets from Pictures with Unity ![]() In the world of game development, creating detailed and realistic assets can be a time-consuming task. However, with the advancement of technology and software, extracting assets from pictures has become more accessible than ever. In this article, we'll explore how to extract assets from pictures using Unity. One common approach is to wash out the contrast of the picture and make everything look like it's covered in white powder. This method can result in a decent approximation, but some software will do basic attempts at removing lighting from the object. However, there are several caveats to this process. A more advanced technique is photogrammetry, which captures the lighting on the object. With photogrammetry, you can take a mobile phone and walk around an object taking a few hundred photos. Software can then turn these photos into a textured 3D model for you. Tools like Photogrammetry automate many of the steps involved in extracting assets from pictures. This has greatly simplified the process, making it easier to create detailed and realistic assets for your game or project. In the early days of normal maps, people wrote tools to extract normals from photos. While these tools weren't particularly accurate, they did provide a mildly plausible result. However, this method didn't fully address the problem of lighting in the photos. ![]() Normal maps are not just surface colors of an object - they also include lighting information. Photo textures all have lighting in them, which can make extracting assets from pictures a challenging task. In conclusion, extracting assets from pictures with Unity is a powerful tool that has greatly simplified the process of creating detailed and realistic assets for your game or project. With photogrammetry and other advanced software tools available, you can create accurate 3D models from just a few hundred photos.
