What does baking an object do?
Render baking creates 2D bitmap images of a mesh object’s rendered surface. These images can be re-mapped onto the object using the object’s UV coordinates. Use Full Render or Textures to create an image texture; baked procedural textures can be used as a starting point for further texture painting.
What is a bake file?
Baking is the process of saving information from a 3D mesh, to a texture file (bitmap). Most of the time, this process involves two meshes, a high poly mesh and a low poly mesh: A high poly mesh has many polygons (often millions) which means it can display high-resolution 3D detail.
What is the purpose of baking in Blender?
Baking, in general, is the act of pre-computing something in order to speed up some other process later down the line. Rendering from scratch takes a lot of time depending on the options you choose. Therefore, Blender allows you to “bake” some parts of the render ahead of time, for select objects.
How can normals be baked in different spaces?
Normals can be baked in different spaces: For materials, the same spaces can be chosen in the image texture options next to the existing Normal Map setting. For correct results, the setting here should match the setting used for baking. Normals in object coordinates, independent of object transformation, but dependent on deformation.
How is baking done in the render settings?
Cycles uses the render settings (samples, bounces, …) for baking. This way the quality of the baked textures should match the result you get from the rendered scene. Perform the baking operation. Bake directly from multires object. Type of pass to bake.
What does baking mean in a physics simulation?
Baking Physics Simulations¶. Baking refers to the act of storing or caching the results of a calculation. The result of a simulation is automatically cached to memory when the animation is played, so that the next time it runs, it can be replayed more quickly by reading the results from the memory.
What do you need to know about baking textures?
Baking textures like base color or normal maps for export to game engines. Baking ambient occlusion or procedural textures, as a base for texture painting or further edits. Creating light maps to provide global illumination or speed up rendering in games.
