Is it likely that there will be a gloss map added to the standard material? We're prototyping a move from Unity5 Standard pbr shader (Specular workflow) to BJS and in Unity we put the "glossiness" map in the Specular texture's alpha channel. This glossiness controls the specular power per pixel but also is used as a mip bias when sampling the reflection texture (giving a lovely blurred reflection look). It'd be great to see these features in BJS! While on the topic of reflections... if I load a cube map for the sky reflections, presumably I can go through all StandardMaterial in the scene and set it as the reflectionTexture? Does BJS have a concept of Reflection Probes? That's another feature in Unity that would be nice in BJS!
