Bake Texture

Basic Tag Options Details

Bake Texture

This function lets you render the following to one or more separate image files for selected objects (they must subsequently be applied manually):

If you want to avoid having to subsequently assign the bitmap to a material, then an object, use the Bake Object function. This will, though, greatly limit the control you have opposed to using the manual method.

Note that the Sculpting feature has its own Bake function in Cinema 4D, which is optimized for use with the Sculpting.

Why bake textures?

Let’s assume you want to render an animation, and a complex shader or area shadow has to be rendered for each image. You can, for example, save a lot of render time by baking the shader and projecting it onto the object as a normal image file.

You can even render lighting, bump, Ambient Occlusion, etc. onto the texture, which lets you avoid having to light these objects, depending on your scene (in this case, add an Luminance material channel to your texture).

The integrated optimized mapping makes sure the UV coordinates are placed in such a manner as to not overlap.

How to Bake

Textures are now baked including all Texture tags. Now you simply select the object itself, not the Texture tag to be baked. If the object contains several materials, i.e., Texture tags, they will be baked, taking hierarchy and alpha channels into consideration – exactly as the object would normally be rendered.

Proceed as follows when you want to bake an object’s texture

  1. Select the object in the Object Manager. The object must have a Texture tag.

  2. From the Object Manager, select Objects / Bake Texture. The active object will be assigned a Bake Texture tag.

  3. Change the settings in the newly created tag, as needed.

  4. Nothing will be baked until the Bake button in the Options tab is pressed. The render process will be shown in the preview window in the same tab.

The Bake Texture tag will remain and be saved with the scene so you can keep a good overview of your previous work. An object can have numerous Bake Texture tags!

In addition, several textures can be baked simultaneously – simply select the desired Bake Texture tags and click on Bake.

In rare cases, flawed texture baking can result from inaccuracies in calculation. If this happens, white pixels can be seen, placed randomly on your image file.

Solution: Set the image file or shader’s Blur Offset somewhat higher than 0%.

Make sure the polygon Normals are oriented equally to the outside (i.e. on the side on which the texture is projected) since only these positive polygon sides will be baked.

One more tip:
Make sure the object has a UVW tag. If it does not, one can be created using the Create UVW tag command.
