ZBrush is a powerful software for 3D sculpting and modeling, and it allows users to import OBJ files with textures to add more depth and realism to their projects. Here's a step-by-step guide on how to load OBJ with textures in ZBrush:

1. Prepare your OBJ file and its associated textures. Make sure the textures are in the correct file format (e.g., JPG, PNG) and are properly named to match the corresponding materials in the OBJ file.

2. Open ZBrush and go to the Tool palette. Click on the Import button to bring up the import options.

3. In the import options window, select your OBJ file and make sure to check the 'Enable Colorize' option. This will allow ZBrush to import the textures along with the OBJ file.

4. Once the OBJ file is imported, you can now see the textures applied to the model in the viewport. You can further modify the textures and materials using the various painting and sculpting tools available in ZBrush.

5. If you want to export the textured OBJ file from ZBrush, you can do so by going to the Tool palette again and clicking on the Export button. Make sure to select the appropriate export options and file format to preserve the textures.

By following these steps, you can easily load OBJ files with textures in ZBrush and take your 3D sculpting projects to the next level. Experiment with different textures and materials to create stunning visual effects and bring your creations to life.
