What is texture baking?

Texture baking involves transferring information from a 3D model onto a texture map. Typically, this occurs between two versions of the model, such as a high-poly and low-poly version.

This process is crucial for real-time applications as it reduces computational demand, optimizing performance. On this page, we'll provide essential insights into baking along with valuable tips and tricks to simplify the process for you.

Texture Baking


When is baking necessary?

  • Texture baking from high-poly to low-poly: To transfer the material information from a high-poly model to a low-poly version of it. 
  • Normal baking: To retain mesh details in the normal texture map. It is commonly used when baking from high-poly to low-poly to prevent detail loss. 
  • Ambient Occlusion baking: To enhance the depth of a model by saving shadow information into an Ambient Occlusion map. 
  • Texture baking for two versions of a model with different UVs: To preserve the material information between two versions of a model with different UV layouts

In the following, you can see an interactive example of texture baking on a 3D model. The model on the left has been remeshed, new UVs have been created and textures have been baked:


What are baking artifacts?

If you are baking textures, you probably heard of the term “artifacts”. Here you have an explanation of this and other important terms for baking:

  • Baking Artifacts: Visual imperfections or errors that may occur during the texture baking process, such as seams, stretching, or aliasing. 
  • UV Layout: The arrangement of UV coordinates on a 2D plane representing the texture space of a 3D model. 
  • Normal Map: A texture map that encodes surface normals to simulate high-resolution surface details on low-poly models. 
  • Ambient Occlusion Map: A texture map that represents the occlusion of ambient light, enhancing the depth and realism of 3D models.

Common challenges in manual baking

UV Unwrapping Properly unwrapping UVs to ensure consistent texture mapping across both models 
Normal Map Generation Generating accurate normal maps that capture surface details while avoiding distortions and smoothing errors. 
Texture stretching Minimizing texture stretching and distortion caused by differences in UV mapping between the original and new UV layouts. 
Texture padding Adding sufficient padding between UV islands to prevent texture bleeding and artifacts caused by mipmapping and texture filtering during rendering, while not wasting UV space. 
Material Consistency Ensuring consistency in material properties and texture application between the models for seamless rendering results. 
Optimization for Real-Time Optimizing the model for real-time rendering, balancing texture resolution and performance while maintaining visual quality. 
Artifact Removal Identifying and correcting baking artifacts such as aliasing, smoothing errors, and texture stretching to achieve clean and accurate texture maps.
