View Full Version : Help with Maya using Spec and Reflection Maps

Hi,

I'm coming from a LightWave background where in the layered surface editor there is an option for specularity and reflection. I usually paint greyscale maps for these attributes and map them to the reflection and specularity channels in LightWave.

In Maya, I'm having trouble understanding how to use image maps for these attributes. I'm using a blinn shader and there is specular color, specular rolloff, ecentricity, reflectivity and reflective color. I've read up on these attributes and I'm not sure where to add my maps.

Where does a specular map get added when using a blinn shader? I heard specular rolloff and I've also read specular color. Which is it? From my understanding specular color is just for tinting the specular reflection. I would think reflectivity is the attribute that gets mapped with my reflection map, but I've read the reflection color controls what is reflected and reflectivity controls the intensity.

Can someone please explain how this works?

Thanks,

Wes

The equivalent of a spec map in LW is the specular rolloff in Maya. If you want to use a reflection map, map the reflectivity attribute.
