TILTPIXEL partner and artist Ramy Hanna explores the creation of realistic 3D rugs in his latest V-Ray for 3ds Max tutorial. Ramy, a frequent presenter at conferences, reminds artists that “textures can be approached multiple ways.” However, some methods provide better results than others, producing visually accurate textures while offering creative control and fast results. Here, Ramy dissects the options and weighs in on his methods of choice.
Per area is the default setting. This setting simply means that for every square inch in the scene there are X number of strands. Switching to Per face tells V-Ray to place X number of strands within each face. I have found this method to be more consistent for giving me the results that I desire. However, keep in mind that small faces will have the same number of strands as large faces, so it really comes down to the effect you are trying to achieve.
Without Distance Tex
With Distance Tex
In this map, you can specify which objects in the scene will control the density of the fur. Here, I applied the base of the lamp and the legs of the coffee table. Where these objects exist in the scene, the Density map will generate zero strands of fur. The distance parameter in this map allows you to control how far from these objects the fur will begin to generate.
This map not only applies to fur, but any other texture where you want objects in the scene to control how maps are changed. Very powerful indeed!
These are simply a few examples of the ways in which fur can be adjusted and controlled. Once you begin playing with the settings, you will have a better understanding of how to control the look you are trying to achieve…and the possibilities are endless.
