Mesh map settings

Setting

Function

Output size

Define the X and Y resolution of generated mesh maps. Click the lock to allow for non-square resolutions.

Dilation width

Adjust how far the baked information extends beyond the boundaries of UV islands.

Apply diffusion

Enable this box to apply diffusion to the edges of generated information.

Setting

Function

Use Low poly mesh as high poly mesh

Enable this setting to bake maps based on your project mesh.

High definition meshes

Add high poly meshes to your project to make from a high poly mesh onto the low poly mesh in your project. Multiple meshes can be imported.

Cage

Determine how the baking cage is generated.

• Distance based: Inflate the vertices away from the mesh a uniform distance across the model to create a cage.
• Automatic (experimental): Painter will analyse your mesh and generate a cage automatically, trying to keep the cage close to the surface without creating intersections for best results.
• Custom file: Import a file that you have created to use as the cage. Note that imported files must have the same number of vertices as the base mesh to work correctly.

Ignore backface

Toggle whether back-faces are ignored while baking. This can help reduce artifacts, but can also cause errors in certain edge-cases.

Match

Change how the Baker determines whether to include objects while baking:

• Always: Include all high poly meshes that are hit within the cage while baking.
• By mesh name: For each cage, only bake meshes with the corresponding mesh suffix.

Low poly mesh suffix

When using Match By mesh name, use this suffix to define low poly meshes.

High poly mesh suffix

When using Match By mesh name, use this suffix to define high poly meshes and match them with the corresponding low poly mesh.

Antialiasing

Adjust the amount of antialiasing in the generated maps.

Setting

Function

Color source

Change how the baked colors of the ID map are determined:

• Vertex Color
• Material Color
• File ID
• Mesh ID/Polygroup

Color Generator

When using File ID or Mesh ID/Polygroup as the color source, determine how colors are generated:

• Random
• Hue shift
• Grayscale

Setting

Function

Secondary rays

Change the number of secondary rays. More rays can yield better results at the cost of increased processing time.

Min Occluder distance

Adjust the minimum distance for rays to travel to hit high poly geometry and impact the resulting AO map.

Max occluder distance

Rays that extend further than this distance without hitting the high poly mesh are considered to not be occluded and will not affect the AO map.

Relative to bounding box

When this box is checked, other settings that refer to distance are based on the bounding box of the project mesh. So a distance of 1 is equal to the size of the bounding box.

Spread angle

Adjust the angular range of generated rays. A higher spread angle allows a surface to be occluded more easily by geometry that is not positioned perpendicularly away from the surface.

Distribution

Select how rays are distributed.

Ignore backface

Change whether backfaces are considered to occlude objects.

Self occlusion

Select which meshes should affect ambient occlusion for the current mesh.

Attenuation

Change how occlusion is attenuated by occluder distance.

Ground plane

Enable this to create a ground plane that acts as an occluder.

Ground plane offset

Change the position of the ground plane.

Setting

Function

Method

Choose how to generate the curvature map.

Secondary rays

Adjust how many secondary rays are used to generate the curvature map. More secondary rays can produce better results at the cost of increased processing time.

Sampling radius

Adjust how far the baker searches to calculate the curvature of the current point.

Relative to Bounding box

When this is checked, all distances are based on the size of the mesh bounding box.

Self intersection

Choose which objects will be considered when determining curvature.

Auto tonemapping (per UV tile)

Leave this checked to automatically adjust the tonemap curvature maps on a per UV tile basis.

Tonemapping Min

If auto tonemapping is disabled, adjust the minimum value for tonemapping.

Tonemapping Max

If auto tonemapping is disabled, adjust the maximum value for tonemapping.

Setting

Function

Mode

Select whether to generate an all axis position map, or only calculate position for a selected axis.

Axis

If Single Axis mode is selected, use this setting to choose which axis to calculate.

Normalization type

Change how position values are normalized, either with a Bounding Box, Bounding sphere, or disable normalization.

Normalization scale

Change what is considered the maximum bounds of the position space.

Setting

Function

Secondary rays

Change the number of secondary rays. More rays can yield better results at the cost of increased processing time.

Min Occluder distance

Adjust the minimum distance for rays to travel to hit high poly geometry and impact the resulting thickness map.

Max Occluder distance

Rays that extend further than this distance without hitting the high poly mesh are considered to not be occluded and will not affect the thickness map.

Relative to bounding box

When this box is checked, other settings that refer to distance are based on the bounding box of the project mesh. So a distance of 1 is equal to the size of the bounding box.

Spread angle

Adjust the angular range of generated rays. A higher spread angle allows a surface to be occluded more easily by geometry that is not positioned perpendicularly away from the surface.

Distribution

Select how rays are distributed.

Self occlusion

Select which meshes should affect thickness for the current mesh.

Normalization

Change how thickness values are normalized.

Setting

Function

Normalization

Change how height values are normalized.

Scaling divisor

If Normalization is set to Manual, use this slider to adjust the scaling divisor and adjust height map normalization.

Setting

Function

Secondary rays

Change the number of secondary rays. More rays can yield better results at the cost of increased processing time.

Min Occluder distance

Adjust the minimum distance for rays to travel to hit high poly geometry and impact the resulting bent normals map.

Max Occluder distance

Rays that extend further than this distance without hitting the high poly mesh are considered to not be occluded and will not affect the bent normals map.

Relative to bounding box

Whenn this box is checked, other settings that refer to distance are based on the bounding box of the project mesh. So a distance of 1 is equal to the size of the bounding box.

Spread angle

Adjust the angular range of generated rays. A higher spread angle allows a surface to be occluded more easily by geometry that is not positioned perpendicularly away from the surface.

Distribution

Select how rays are distributed.

Ignore backface

Choose whether to treat backfaces as occluders.

Self occlusion

Select which meshes should impact bent normals for the current mesh.
