and for the the wall texture he used a fresnal for the reflectivity glossiness. In this tutorial of chaosgroup Material part 2 he used the reflectivity map and set it as a texbitmap in both highlight glossines ans reflection glossiness. The specularity map is used to reflect the light form bright object "lightsource" and sun and let only some part of the material " or object that we have affected it " reflect them because of the iregularity of the surface like in concret. The best way to create this kind of rendering quality is playing around the setting of both Highlight Glossiness and Reflection So the highlight is not as sharp if compare to reflection from smoother surfaces. Uneven surfaces create many reflecting angles for light to bounce around. Objects like matte finish metal, wood and some plastic materials do not reflect the lightsource clearly due to its uneven surfaces. You don't always get clear reflection from reflective material. Very reflective, filer color may be an effective way to change the object’s appearance.
Will change based on the strength of the reflections themselves.
On each of the renderings below the color of the reflections change. You can see that by changing the filter color The filter color is used to apply color to reflections. I don't think that the reflection filter is used for the specularity this is what it's said about it in Vray for sketchup " manual " Ĭan we get this result with Vray for sketchup ? I had worked for hours to get the aspect that i've seen in the demo in this site : but still don't get it.
