This page provides information on the Bake tab of the V-Ray BakerTool.
Parameters
Baking Mode – Specifies the baking mode.
Maps Baking – V-Ray creates texture maps based on an object's appearance in the rendered scene. The textures are then "baked" into the object.
Projection Baking – V-Ray does not bake to the specified object itself, but traces an offset ray from the object down the normal and shades whatever surface is hit underneath it.
UV attribute – Specifies the name of the uv attribute on the baked geometry. The attribute name should be the same across all objects for the baking process to work as expected.
Auto Range – Evaluates the Min/Max range of the UV attribute and populate the UV Min and UV Max parameters below. When baking multiple objects, the evaluated range is based on the Min/Max range for the entire set of objects.
UV Min/UV Max – Specifies the UV domain to bake when Auto Range is disabled.
UDIM – When enabled, bakes the textures in UDIMs.
UDIM from Selected Objects – When enabled and multiple objects are selected, bakes the objects in the same UDIMs.
Dilation (Edge Padding) – Specifies the number of pixels to expand around geometry.
Projection Settings
The following options are available only when Baking Mode is set to Projection Baking.
Mode – Specifies the direction of the traced ray.
Outside – The ray is traced along the normal vector.
Inside – The ray is traced in the opposite direction of the normal vector.
Outside first, then Inside – The ray is first traced along the normal vector. If no intersection occurs, then a second ray is traced in the opposite direction of the normal vector.
Inside first, then Outside – Same as Outside first, then Inside but in reversed order.
Closest – Two rays are traced in both directions and the intersection that occurs closest to the surface is chosen.
Normals – Specifies which normals to use when shooting rays.
Geometry – Uses normals of the geometry.
Smooth – Uses normals generated by V-Ray.
Max Depth – Specifies the maximum depth for the traced rays, in scene units.
Cage Offset – Offsets the ray's initial location. Used when the baked low poly object and the high res geometry overlap perfectly, causing an inability to intersect the rays with the low poly geometry.
Guides – When enabled, allows you to control the Show Cage and Visualize Depth parameters.
Show Cage – Generates a wireframe preview of the baked low poly geometry based on the Cage Offset parameter.
Visualize Depth – Generates a clipping plane which can be useful when debugging projection artifacts.
Clip Settings
Axis – Specifies the clipping plane axis.
Clipper Position – Specifies an offset for the clipping plane along the specified Axis parameter.
Invert – When enabled, flips the clipping plane's orientation.
