So you've created an awesome OBJ model in Blender, but now it's time to add some texture to bring it to life. Here's a simple guide on how to texture an OBJ in Blender.

Step 1: Import your OBJ model into Blender and make sure it's properly positioned and scaled in the scene.

Step 2: Open the 'Shading' workspace in Blender, which will allow you to work with materials and textures.

Step 3: Select the object you want to texture in the 3D view, then go to the 'Materials' tab in the Properties panel.

Step 4: Click on the 'New' button to create a new material for your object. You can then adjust the base color and other material properties to your liking.

Step 5: Now it's time to add the texture. In the 'Shading' workspace, click on the 'Texture' tab, then click on the 'New' button to create a new texture.

Step 6: Choose the type of texture you want to add, such as 'Image Texture' for a specific image or 'Noise Texture' for procedural textures.

Step 7: Once you've added the texture, connect it to the 'Base Color' input of your object's material. You can also add other texture maps, such as roughness or normal maps, to further enhance the realism of your model.

Step 8: Finally, make sure to UV unwrap your model if you're using image textures, so that the textures can be properly applied to the geometry.

That's it! You've successfully textured your OBJ model in Blender. Feel free to experiment with different textures and material properties to achieve the look you want for your 3D model.
