Are there no built in shaders that use a specular map?

Questions & Answers

Hi I just wanted to add a specular map to a material but none of the built-in shaders seem to have an option for this. Do I need to write my own shader for this? ... I just thought it would be common enough to be built-in.

Thanks

I believe gloss is stored in the base texture's alpha channel of a built-in specular shader.

I'm surprised by that. I'm quite sure there are specular built in shaders. Maybe you just missed the part that specular map has to be stored in alpha of main texture?
