Creating a Velvet/Suede finish with Vray or Mental Ray
by Jamie Cardoso
The following tutorial works for both V-Ray and mental ray.
One of the most distinctive characteristics of the velvet/suede finish is its soft textured effect with two contrasts that transcend across the entire surface. This effect is more noticeable on the edges/rim of the surface.
To emulate this material, simply do the following:
1- Go into your existing “Diffuse” map toggle first.
Or
2- In the “Diffuse map” parameters, click on its “Bitmap” toggle to access the “Falloff” procedural map from the “Material/Map Browser” dialog. Double click to select it.
3-The “Replace Map” dialog should be prompted. Choose to “Keep old map as sub-map” and “OK” to close the dialog. The “Falloff parameters” should be loaded.
4- With the “Falloff parameters” loaded, one can clearly see its exquisite effects from the material slot thumbnail. The next phase is to create two variations of the same material in order to emulate the previously described “finish”. The “Color Correction” procedural map is one of many tools that can help achieve that:
In the “Front: Side” group, click on the “Front” toggle to access its “Bitmap” parameters; followed by clicking on its “Bitmap” toggle to choose the “Color Correction” map from the “Material/Map Browser” dialog. Also, choose to “Keep old map as sub-map” option when the “Replace Map” dialog is prompted.
