The AO and cavity content was moved to two separate textures and hooked up in the appropriate slot in the shader. Then drag Opacity onto the A channel and choose Gray Channel from the drop-down. 1 Answer Sorted by: 2 For Specular based shader system you need: specular texture (effects the reflection color) glossiness texture (effects the reflection sharpness) In Cycles is used roughness, which is inverse of glossiness In Blender Internal it is called hardness For Metalness based shader system you need: Converting to the specular workflow from the metalness workflow is easy as well.

If your base content was not calibrated, you will see much bigger differences in the conversion. The reason for this is that metals conduct electricity, which means that most photons (which are electromagnetic waves) reflect off the surface, and any photons that pass through the surface are absorbed rather than diffused, so metals typically do not have a diffuse component. At this point, for this project, you can jump right to 4. It should be empty. adjust the input levels towards the middle. For many online applications, it is simply overkill. Thus, figuring out exactly what type of material youre representing is very important when it comes to finding the right reflectance value.
