Description
Texture baking is the last step when preparing models for real-time applications. During decimation, the mesh has been reduced in size. Texture baking transfers features from the high resolution mesh to a texture. The texture is then applied to the low resolution mesh in order to bring back the lost details.
Baking requires a low poly mesh with UV coordinates. The coordinates can be generated using the UnwrapMeshTask.
This task utilizes the following tools:
Options
| Option | Type | Required | Default | Description |
|---|---|---|---|---|
| highPolyMeshFile | string | yes | High resolution mesh file name. | |
| highPolyDiffuseMapFile | string | no | Diffuse texture for high resolution mesh. | |
| lowPolyUnwrappedMeshFile | string | yes | Low resolution (decimated) mesh file name. | |
| mapBaseName | string | no | Base name for baked texture map files. | |
| mapSize | number | yes | 2048 | Baked map size in pixels. |
| maxRayDistance | number | no | 0.001 | Maximum search distance when projecting rays from the high poly to the low poly mesh. |
| bakeDiffuse | boolean | no | true | Bakes a diffuse map if true and highPolyDiffuseMapFile is not empty. |
| bakeOcclusion | boolean | no | true | Bakes an ambient occlusion map if true. |
| bakeNormals | boolean | no | true | Bakes a normal map if true. |
| bakeTest | boolean | no | false | Bakes a test map for checking the projection quality if true. |
| occlusionRays | number | no | 128 | Number of sample rays for ambient occlusion, between 1 and 512. |
| occlusionConeAngle | number | no | 165 | Maximum cone angle for ambient occlusion sample rays, between 1 and 165 |
| occlusionAttConstant | number | no | 1 | Ambient occlusion attenuation, constant factor. |
| occlusionAttLinear | number | no | 0 | Ambient occlusion attenuation, linear factor. |
| occlusionAttQuadratic | number | no | 0 | Ambient occlusion attenuation, quadratic factor. |
| tangentSpaceNormals | boolean | no | false | Bakes normals in tangent space if true. |
| timeout | number | no | 0 | Maximum task execution time in seconds (default: 0, uses timeout defined in tool setup). |
| tool | string | no | “XNormal” | Baking tool to use: “XNormal” or “RapidCompact” |
