Does specular(roughness) work on ES2 with static/baked lighting ?

I tried and it doesn’t seem to work. Diffuse/normal maps work with baked lighting on ES2, but no specular highlights show (material has roughness map and it shows in the Editor/PIE with SM5 preview).

Is it even supported? A bug maybe?

Thanks

[MENTION=11153]Chris Babcock[/MENTION] I wonder if it doesn’t work with ES2 at all or if I need HDR on to get roughness to work …

I figured what the issue was - I forced fully rough and non-metallic in my project settings. So changing and tweaking materials didn’t have any effect.
