VTK PBR Mapping Test Failing #186
Description
The VTK test TestAnariPBRMapping is not rendering the correct image when using the VisRTX back-end.
There are four texture maps being used (vtk_Anisotropy.png, vtk_Base_Color.png, vtk_Material.png, vtk_Normal.png). When the vtk_Material.png texture is used the rendering is the worst. This texture contains values for occlusion, roughness, and metallic and are extracted into individual samplers. Setting the metallic parameter directly as a Float32 produces better results.
Expected Result
VisRTX back-end using all of the VTK PBR textures
VisRTX back-end without extracting the metallic texture and using 0.5 as the metallic value. All of the other textures are used.
