Bake Groups #

Bake Groups are special folders with slots for high and low poly meshes and can be used to isolate different elements of your model to prevent errors at intersection points. You can use as many or as few groups as you like.

High #

The High bake group is used for high-poly mesh or meshes from which the data will be baked. Its preview is off by default. To view the high-poly model, click the eye icon next to the High bake group in your Scene hierarchy, or press the Preview or Hide High-poly button on the Bake Project Settings.

Low #

The Low bake group is used for low-poly mesh or meshes on which the data will be baked.

Setting	Description
Exclude When Ignoring Groups	Exclude this mesh from the Ignore Groups option for passes such as AO, Thickness, and Lighting.

Preview

Setting	Description
Auto-Bake	Selects a method by which maps are automatically re-baked while offset or skew parameters are edited. “Quick” mode will attempt to re-bake only small subsets of the mesh that have changed and use slightly lower quality for speed. Quick mode is not able to preview AO or Material bake outputs.
Show Offset	Displays the cage mesh offset in the viewport.
Offset Alpha	Set the visibility of the offset cage that the baker uses.
Show Skew	Display the cage mesh skew directions in the viewport.

Cage

Setting	Description
Minimum Offset	This specifies the minimum distance the cage will trace from the low-poly mesh. This value corresponds to black in the offset map.
Maximum Offset	This specifies the maximum distance the cage will trace from the low-poly mesh. This value corresponds to white in the offset map.
Max Ray Distance	This value limits the length of rays traced inward from the cage surface. This is useful for limiting bake intersections to distances beyond a specified threshold. A value of zero indicates no limit.
Paint Offset	Opens a painting tool to edit the offset map for the low-poly cage. This map adjusts the cage offset, allowing for a better fit around the high-poly model. You can also select this tool from the toolbar.
Estimate Offset	Overwrites the current cage offset map with a best-guess height estimate.
Paint Skew	Opens a painting tool to edit the skew map for the low-poly cage. A skew map adjusts the directions along which baking rays are traced. This map blends between vertex normal and face normal directions, granting some ability to correct skewed artifacts in the bake result. You can also select this tool from the toolbar.
Use Custom Cage	Use a custom cage when baking. You may want to do this for better fine-grain control over the location of cage points.
