a bit tarnished but it has enough variation to give us something nice to play with. of course you need to keep in mind what the object is made of and how that affects light reflection. You can also do a few other things with a spec map, such as add color, add areas of stains, or smears etc. while using the diffuse as a base is a good start that only get’s you partially there. Years ago I was taught that you simply copied the objects diffuse texture, added brightness or contrast in some areas and then called it good. Hit up Google for more a more detailed in-depth definition if you so desire. An orange with it’s rough undulating surface will have a more “scattered” specular highlights(s) vs. the nature of object’s surface as well as a few other things will affect how clearly you can see that source being reflected. What is specularity? The short dirty answer is, specularity is the reflection of an object’s light source or sources on its surface. Programs used: Photoshop, 3Ds Max (optional),UDK (optional) This tutorial will cover creating and applying a convincing specular map. Now that I’ve buffed up my skill set and re-educated myself in a lot of things, I thought it’s a great time to share some of what i’ve learned during my toiling. I’ve wanted to do this for a long time but had not had the chance.
