If you are a 3D modeler or artist looking to showcase your work in Second Life, you may want to upload your OBJ files to the platform. Here's a step-by-step guide on how to do it. First, make sure your OBJ file is ready for upload. This means it should be in the correct scale and have its texture maps applied. Next, log in to Second Life and go to the Build menu. Select Upload and then Model. Choose your OBJ file from your computer and then wait for it to upload. Once it’s uploaded, you can adjust its positioning and size. Finally, make sure to set the correct permissions for your model so that others can interact with it. By following these steps, you can share your 3D creations with the Second Life community and bring your designs to life in the virtual world.
