Here is the caller graph for this function:

void Shader::ShaderVisitor::setAllowedToModifyStateSets

(

bool

allowed

)

Set if we are allowed to modify StateSets encountered in the graph (default true).

If set to false, then instead of modifying, the StateSet will be cloned and this new StateSet will be assigned to the node.

This option is useful when the ShaderVisitor is run on a "live" subgraph that may have already been submitted for rendering.

void Shader::ShaderVisitor::setAutoUseNormalMaps

(

bool

use

)

Automatically use normal maps if a file with suitable name exists (see normal map pattern).

void Shader::ShaderVisitor::setAutoUseSpecularMaps

(

bool

use

)

void Shader::ShaderVisitor::setClampLighting

(

bool

clamp

)

Set whether lighting is clamped for visual compatibility with the fixed function pipeline.

void Shader::ShaderVisitor::setForcePerPixelLighting

(

bool

force

)

By default, only bump mapped objects use per-pixel lighting. Setting force = true will cause all shaders to use per-pixel lighting, regardless of having a bump map.

void Shader::ShaderVisitor::setForceShaders

(

bool

force

)

By default, only bump mapped objects will have a shader added to them. Setting force = true will cause all objects to render using shaders, regardless of having a bump map.
