The video provides a detailed guide on generating 3D meshes using the AI platform Trellis from Hugging Face, followed by instructions on importing and exporting the mesh in Blender, including texture management for use in Unity. It also suggests alternative resources for mesh generation, recommending users to explore 3D Arena for high-quality open-source models if Trellis becomes outdated.
The video provides a step-by-step guide on how to generate 3D meshes using AI tools, specifically focusing on a platform called Trellis from Hugging Face. The process begins with the user looking up Trellis and uploading an image to the platform. After generating the mesh, the user is instructed to extract the generated data (referred to as GB) and download it. This initial phase is straightforward and sets the foundation for further manipulation of the mesh in a 3D software environment.
Once the mesh is downloaded, the tutorial transitions to Blender, a popular 3D modeling software. The user is guided to delete any existing objects in the Blender scene and then drag and drop the downloaded GB file. The next step involves importing the mesh in the glTF format, which is compatible with Blender. After successfully importing the mesh, the user is instructed to export it as an FBX file, ensuring to apply transformations to maintain the correct scale and orientation of the model.
However, the video notes a limitation in the process: the exported FBX file does not include textures. To resolve this, the user is directed to switch to the image editor in Blender, where they can choose the embedded image associated with the mesh. The tutorial emphasizes the importance of saving this texture separately, as it will be needed for proper material assignment in game engines like Unity.
For users who plan to use the generated mesh in Unity, the video provides additional instructions on how to assign the saved texture. After importing the mesh into Unity, the user is advised to select the imported model and navigate to the materials section. Here, they can extract the materials and assign the previously saved texture, ensuring that the model appears correctly in the game engine.
Towards the end of the video, there is a suggestion to consider alternative resources for generating meshes. The presenter advises viewers to avoid using Trellis if it becomes outdated and instead recommends visiting 3D Arena. By filtering for open-source models and selecting a suitable option from the leaderboard, users can find high-quality models to use in their projects, ensuring they have access to the latest and most effective tools for mesh generation.
