Function documentation

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasMetalnessTexture() const

Whether the material has a metalness texture.

Returns true if any of the MaterialAttribute::MetalnessTexture or MaterialAttribute::NoneRoughnessMetallicTexture attributes is present, false otherwise.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasRoughnessTexture() const

Whether the material has a roughness texture.

Returns true if any of the MaterialAttribute::RoughnessTexture or MaterialAttribute::NoneRoughnessMetallicTexture attributes is present, false otherwise.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasNoneRoughnessMetallicTexture() const

Whether the material has a combined roughness/metallic texture.

Returns true if either the MaterialAttribute::NoneRoughnessMetallicTexture attribute is present or both MaterialAttribute::RoughnessTexture and MaterialAttribute::MetalnessTexture are present, point to the same texture ID, MaterialAttribute::RoughnessTextureSwizzle is set to MaterialTextureSwizzle::G and MaterialAttribute::MetalnessTextureSwizzle is set to MaterialTextureSwizzle::B, and ddditionally MaterialAttribute::RoughnessTextureMatrix and MaterialAttribute::MetalnessTextureMatrix are both either not present or have the same value, MaterialAttribute::RoughnessTextureCoordinates and MaterialAttribute::MetalnessTextureCoordinates are both either not present or have the same value, and MaterialAttribute::RoughnessTextureLayer and MaterialAttribute::MetalnessTextureLayer are both either not present or have the same value; false otherwise.

In other words, if this function returns true, roughnessTexture(), roughnessTextureMatrix(), roughnessTextureCoordinates() and roughnessTextureLayer() return values common for both metalness and roughness texture, and the two are packed together with roughness occupying the G channel and metalness the B channel. This packing is common in glTF metallic/roughness materials, which in turn is compatible with how UE4 assets are usually packed. Original rationale for this can be seen here.

The red and alpha channels are ignored and can be repurposed for other maps such as occlusion or transmission. This check is a subset of hasOcclusionRoughnessMetallicTexture() — if that function returns true, this will return true as well.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasOcclusionRoughnessMetallicTexture() const

Whether the material has a combined occlusion/roughness/metallic texture.

Returns true if MaterialAttribute::OcclusionTexture, MaterialAttribute::RoughnessTexture and MaterialAttribute::MetalnessTexture are all present, point to the same texture ID, MaterialAttribute::OcclusionTextureSwizzle is set to MaterialTextureSwizzle::R (or omitted, in which case it's the default), MaterialAttribute::RoughnessTextureSwizzle is set to MaterialTextureSwizzle::G and MaterialAttribute::MetalnessTextureSwizzle is set to MaterialTextureSwizzle::B, and additionally MaterialAttribute::OcclusionTextureMatrix, MaterialAttribute::RoughnessTextureMatrix and MaterialAttribute::MetalnessTextureMatrix are all other not present or have the same value, MaterialAttribute::OcclusionTextureCoordinates, MaterialAttribute::RoughnessTextureCoordinates and MaterialAttribute::MetalnessTextureCoordinates are all either not present or have the same value, and MaterialAttribute::OcclusionTextureLayer, MaterialAttribute::RoughnessTextureLayer and MaterialAttribute::MetalnessTextureLayer are all either not present or have the same value; false otherwise.

In other words, if this function returns true, occlusionTexture(), occlusionTextureMatrix(), occlusionTextureCoordinates() and occlusionTextureLayer() return values common for occlusion, roughness and metalness textures, and the three are packed together with occlusion occupying the R channel, roughness the G channel and metalness the B channel. This packing is common in glTF metallic/roughness materials, which in turn is compatible with how UE4 assets are usually packed. Original rationale for this can be seen here, there's also a MSFT_packing_occlusionRoughnessMetallic glTF extension using this packing in a more explicit way.

The alpha channel is ignored and can be repurposed for other maps such as transmission. This check is a superset of hasNoneRoughnessMetallicTexture() — if this function returns true, that one will return true as well.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasRoughnessMetallicOcclusionTexture() const

Whether the material has a combined roughness/metallic/occlusion texture.

Returns true if MaterialAttribute::RoughnessTexture, MaterialAttribute::MetalnessTexture and MaterialAttribute::OcclusionTexture are all present, point to the same texture ID, MaterialAttribute::RoughnessTextureSwizzle is set to MaterialTextureSwizzle::R (or omitted, in which case it's the default), MaterialAttribute::MetalnessTextureSwizzle is set to MaterialTextureSwizzle::G and MaterialAttribute::OcclusionTextureSwizzle is set to MaterialTextureSwizzle::B, and additionally MaterialAttribute::RoughnessTextureMatrix, MaterialAttribute::MetalnessTextureMatrix and MaterialAttribute::OcclusionTextureMatrix are all other not present or have the same value, MaterialAttribute::RoughnessTextureCoordinates, MaterialAttribute::MetalnessTextureCoordinates and MaterialAttribute::OcclusionTextureCoordinates are all either not present or have the same value, and MaterialAttribute::RoughnessTextureLayer, MaterialAttribute::MetalnessTextureLayer and MaterialAttribute::OcclusionTextureLayer are all either not present or have the same value; false otherwise.

In other words, if this function returns true, roughnessTexture(), roughnessTextureMatrix(), roughnessTextureCoordinates() and roughnessTextureLayer() return values common for roughness, metalness and occlusion textures, and the three are packed together with roughness occupying the R channel, metalness the G channel and occlusion the B channel. This check is present in order to provide support for the MSFT_packing_occlusionRoughnessMetallic glTF extension.

The alpha channel is ignored and can be repurposed for other maps such as transmission.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasNormalRoughnessMetallicTexture() const

Whether the material has a combined normal/roughness/metallic texture.

Returns true if MaterialAttribute::NormalTexture, MaterialAttribute::RoughnessTexture and MaterialAttribute::MetalnessTexture are all present, point to the same texture ID, MaterialAttribute::NormalTextureSwizzle is set to MaterialTextureSwizzle::RG (with the third channel implicit), MaterialAttribute::RoughnessTextureSwizzle is set to MaterialTextureSwizzle::B and MaterialAttribute::MetalnessTextureSwizzle is set to MaterialTextureSwizzle::A, and additionally MaterialAttribute::NormalTextureMatrix, MaterialAttribute::RoughnessTextureMatrix and MaterialAttribute::MetalnessTextureMatrix are all other not present or have the same value, MaterialAttribute::NormalTextureCoordinates, MaterialAttribute::RoughnessTextureCoordinates and MaterialAttribute::MetalnessTextureCoordinates are all either not present or have the same value, and MaterialAttribute::NormalTextureLayer, MaterialAttribute::RoughnessTextureLayer and MaterialAttribute::MetalnessTextureLayer are all either not present or have the same value; false otherwise.

In other words, if this function returns true, normalTexture(), normalTextureMatrix(), normalTextureCoordinates() and normalTextureLayer() return values common for normal, roughness and metalness textures, and the three are packed together with normals occupying the RG channel, roughness the B channel and metalness the A channel. This check is present in order to provide support for the MSFT_packing_normalRoughnessMetallic glTF extension.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasCommonTextureCoordinates() const

In particular, returns true also if there's no extra texture coordinate set used at all. Use hasTextureCoordinates() to distinguish that case.

bool Magnum::Trade::PbrMetallicRoughnessMaterialData::hasTextureLayer() const

Whether the material uses array texture layers.

Returns true if any of the MaterialAttribute::BaseColorTextureLayer, MaterialAttribute::MetalnessTextureLayer, MaterialAttribute::RoughnessTextureLayer, MaterialAttribute::NormalTextureLayer, MaterialAttribute::OcclusionTextureLayer, MaterialAttribute::EmissiveTextureLayer or MaterialAttribute::TextureLayer attributes is present and has a non-zero value, false otherwise.
