Detailed Description

template<typename Renderer, typename ShaderGen>
class TextureBaker< Renderer, ShaderGen >

A helper class for baking procedural material content to textures.

TODO: Add support for graphs containing geometric nodes such as position and normal.

Member Function Documentation

bakeAllMaterials()

void bakeAllMaterials	(	DocumentPtr	doc,
		const FileSearchPath &	searchPath,
		const FilePath &	outputFileName
	)

Bake materials in the given document and write them to disk.

If multiple documents are written, then the given output filename will be used as a template.

setColorSpace()

void setColorSpace ( const string &  colorSpace )

inline

Set the color space in which color textures are encoded.

By default, this color space is srgb_texture, and color inputs are automatically transformed to this space by the baker. If another color space is set, then the input graph is responsible for transforming colors to this space.

setHashImageNames()

void setHashImageNames ( bool  enable )

inline

Set whether to create a short name for baked images by hashing the baked image filenames This is useful for file systems which may have a maximum limit on filename size.

By default names are not hashed.

setOutputImagePath()

void setOutputImagePath ( const FilePath &  outputImagePath )

inline

Set the output location for baked texture images.

Defaults to the root folder of the destination material.

writeDocumentPerMaterial()

void writeDocumentPerMaterial ( bool  value )

inline

Set whether to write a separate document per material when calling bakeAllMaterials.

By default separate documents are written.
