Convert an AI generated image to 3D

Introduction

In this tutorial, we will explore the process of converting an AI-generated image into a 3D model. This method has gained popularity and generated interest on social media platforms. We will use Photoshop for the initial steps, but the techniques can be applied in other 3D software such as Blender or 3D Studio Max.

Step 1: Extracting the Depth Map

To begin, we need to extract a coarse depth map from the image. The depth map provides depth information for each pixel, which is essential for creating the 3D model. In Photoshop, you can use the "depth blur" option in the neural filters menu to generate a black and white depth map. Keep in mind that the accuracy of the depth map may vary, but it should be sufficient for our purposes. Save the depth map as a PNG file.

Step 2: Creating the 3D Model

Next, we will use 3D software such as 3D Studio Max to create the 3D model. Start by setting up reference planes based on the original AI-generated image. Create a sphere and modify its shape using a freeform deformer to resemble an egg shape. Adjust the UVs to avoid stretching and ensure a proper texture mapping. Add a symmetry modifier to replicate the model and check for any open edges that may need welding. Apply a subdivision modifier for smoothness and use the extracted depth map to displace the geometry. Fine-tune the displacement strength and add additional details using a higher-resolution height map. Once satisfied with the model, export it as an FBX file.

Step 3: Applying Materials and Lighting

Import the exported 3D model into a rendering software like Marmoset Toolbag. Set up a material for the model using the original AI-generated image as the albedo texture. Adjust the roughness and apply an occlusion map to darken recessed areas. Utilize subsurface scattering to enhance the organic look of the model. Implement proper lighting, considering the mood of the scene, and use depth of field to create focus and depth. Play around with different lighting setups until you achieve the desired result.

FAQ

Q: Can I use other 3D software instead of 3D Studio Max? A: Yes, you can use software like Blender or any 3D modeling software of your choice to create the 3D model.

Q: How accurate is the depth map obtained from the AI-generated image? A: The depth map is an approximation and may not be completely accurate. However, it should be sufficient for creating the 3D model.

Q: Can I add more details to the 3D model? A: Yes, you can further enhance the details of the 3D model by sculpting, painting, or using additional texture maps.

Q: What is subsurface scattering? A: Subsurface scattering is a technique used to simulate the behavior of light as it penetrates and scatters within translucent materials, providing a more realistic and organic appearance.

Q: Are there any specific considerations for lighting the scene? A: When lighting the scene, consider the desired mood and atmosphere, and experiment with different lighting setups to achieve the desired result.

Q: What file format should I use to export the 3D model? A: Export the 3D model as an FBX file, which is commonly supported by various 3D software and rendering engines.
