◆ saveTextures()

virtual void Ogre::HlmsDatablock::saveTextures ( const String folderPath,
set< String >::type &  savedTextures,
bool  saveOitd,
bool  saveOriginal,
HlmsTextureExportListener listener 
)
virtualinherited
Remarks
It's possible to set both saveOitd & saveOriginal to true, but will likely double storage requirements (2x as many textures). Setting both to true is useful for troubleshooting obscure Ogre bugs.
Parameters
folderPathFolder where to dump the textures.
savedTextures[in/out] Set of texture names. Textures whose name is already in the set won't be saved again. Textures that were saved will be inserted into the set.
saveOitdWhen true, we will download the texture from GPU and save it in OITD format. OITD is faster to load as it's stored in Ogre's native format it understands, but it cannot be opened by traditional image editors; also OITD is not backwards compatible with older versions of Ogre.
saveOriginalWhen true, we will attempt to read the raw filestream of the original texture and save it (i.e. copy the original png/dds/etc file).

Reimplemented in Ogre::OGRE_HLMS_TEXTURE_BASE_CLASS.

◆ setAlphaTest()

virtual void Ogre::HlmsDatablock::setAlphaTest ( CompareFunction  compareFunction,
bool  shadowCasterOnly = false,
bool  useAlphaFromTextures = true 
)
virtualinherited

Sets the alpha test to the given compare function.

CMPF_ALWAYS_PASS means disabled.

See also
mAlphaTestThreshold. Calling this function triggers a HlmsDatablock::flushRenderables
Remarks
It is to the derived implementation to actually implement the alpha test.
Parameters
compareFunctionCompare function to use. Default is CMPF_ALWAYS_PASS, which means disabled. Note: CMPF_ALWAYS_FAIL is not supported. Set a negative threshold to workaround this issue.
shadowCasterOnlyWhen true, only the caster should use alpha testing. Useful if you want alpha blending (i.e. transparency) while rendering normally, but want semi-transparent shadows.
useAlphaFromTexturesWhether you want the diffuse texture's alpha to influence the alpha test Most likely you want this to be true, unless you're customizing the shader and have special use for alpha testing

◆ setAlphaTestThreshold()

virtual void Ogre::HlmsDatablock::setAlphaTestThreshold ( float  threshold)
virtualinherited

Alpha test's threshold.

See also
setAlphaTest
Parameters
thresholdValue typically in the range [0; 1)

◆ setBlendblock() [1/2]

void Ogre::HlmsDatablock::setBlendblock ( const HlmsBlendblock blendblock,
bool  casterBlock = false 
)
inherited

Sets a new blendblock that matches the same parameter as the input.

Decreases the reference count of the previous mBlendblock. Runs an O(N) search to get the right block. Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
blendblock@See HlmsManager::getBlendblock
casterBlockTrue to directly set the blendblock to be used during the shadow mapping's caster pass. Note that when false, it will reset the caster block to the same as the regular one.

◆ setBlendblock() [2/2]

void Ogre::HlmsDatablock::setBlendblock ( const HlmsBlendblock blendblock,
bool  casterBlock = false 
)
inherited

Sets the blendblock from the given pointer that was already retrieved from the HlmsManager.

Unlike the other overload, this operation is O(1). Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
blendblockA valid block. The reference count is increased inside this function.
casterBlockTrue to directly set the blendblock to be used during the shadow mapping's caster pass. Note that when false, it will reset the caster block to the same as the regular one.

◆ setMacroblock() [1/2]

void Ogre::HlmsDatablock::setMacroblock ( const HlmsMacroblock macroblock,
bool  casterBlock = false 
)
inherited

Sets a new macroblock that matches the same parameter as the input.

Decreases the reference count of the previously set one. Runs an O(N) search to get the right block. Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
macroblock@See HlmsManager::getMacroblock
casterBlockTrue to directly set the macroblock to be used during the shadow mapping's caster pass. Note that when false, it will automatically reset the caster's block according to HlmsManager::setShadowMappingUseBackFaces setting.

◆ setMacroblock() [2/2]

void Ogre::HlmsDatablock::setMacroblock ( const HlmsMacroblock macroblock,
bool  casterBlock = false 
)
inherited

Sets the macroblock from the given pointer that was already retrieved from the HlmsManager.

Unlike the other overload, this operation is O(1). Calling this function triggers a HlmsDatablock::flushRenderables

Parameters
macroblockA valid block. The reference count is increased inside this function.
casterBlockTrue to directly set the macroblock to be used during the shadow mapping's caster pass. Note that when false, it will automatically reset the caster's block according to HlmsManager::setShadowMappingUseBackFaces setting.
