Due to the fibers, which diffuse light, nearly all of the fabrics look somewhat lighter at an acute angle. An example is shown in Fig. 9: The Color channel shows either noise or bitmap texture almost all of the samples in Screen Above mode have Fresnel – depending on the view angle relative to the normal surface – overlaying the color. Using just a few surface parameter channels, you can generate completely different materials in terms of their visual perception. Various noises, weathering and gradients create streaks and dirt on the surface. As opposed to bitmap textures, they never repeat, which is very critical for large surfaces, especially in the event of exterior rendering (please, note the grey stucco in the top-left picture of Fig.1 and the brickwork in the bottom).

I would like to note that CineRender in Archicad is mostly focused on procedural shaders they can often be used for more quickly and attractively rendering bricks, parquet, tiles and stucco. Most situations require standard surfaces additional surfaces can be retrieved from the library folder. Let’s proceed with the surface parameter settings.
