Specular & alpha mapping

Questions & Answers
1

Hello,

I was wondering how to have a alpha map and specular map in unity3d. So far I know is that whenever I need to use a specular mapping I place it into the alpha of my texture but what if I need to use a specular and alpha? Can they be placed together or can I use my normal map aswell?

Thanks in advance.

Use the transparent bumped specular shader:

Allows for specularity, bumpmaps, and alpha.
