In a scene with a procedural skybox and no sun, a handful of bright areas on a lightmap static sphere. The sphere uses a Standard shader with 0.95 Smoothness, black Albedo, and white Specular. The unexpected hot spots occur whether or not a reflection probe is used. These highlights do not appear if the sphere is set to lightmap dynamic and the scene is rebaked.

Notes:
- Directional Specular mode will be “deprecated“ in 5.5.0f1 and will be removed entirely in 5.6. Currently, no fixes are planned for this feature.
