• [Hydra] Fixed bug that could cause a crash if the tangent attributes can't be computed due to the lack of normals or uvs
• [Hydra] Fixed bug that could cause that matting or visivility do not work with PointInstancer using instanceable primitives as prototypes
• [Hydra] Fixed bug that could cause viewport updating problems in the instances visibility or matte options
• [Hydra] Fixed bug that could cause problems while working with multiple UV maps
• [Hydra] Fixed bug in the Redshift and RenderVars LOPs single layer EXR files when there are no additional AOVs
