Sub-Structure - The surface of a pure, elastic body model has a high degree of freedom, which causes the object to easily distort.If you are coming to LightWave from Maya, the function that is most similar from that application is “Damping.” A value of 1.0 gives the medium a character close to that of molasses. To simulate behavior within a normal atmosphere at sea level, a value of. A negative number amplifies a collision of the cloth object. This allows the simulation of a wide range of gaseous or even liquid media as the environment for the physical simulation. The default setting is 1.0 raising this number increases the resistance and lowering to a number between 1.0 and 0.0 decreases the resistance. For example, this affects how quickly a cloth object moves through the virtual air in the scene by determining how “thick” the virtual air is. Resistance controls the amount of resistance of the environmental medium in which the simulation is taking place. Resistance - This parameter is not a characteristic of the object itself, even though it can be set per object.Left = lower viscosity, Right = higher viscosity The cloth with the higher Viscosity value tends to keep its shape more. Here, a ball is moving up, pushing the piece of a cloth. The pieces of cloth below are the same except for the Viscosity parameter. If an object bounces, a higher Viscosity value will have less bounce motion because the Viscosity absorbs the bouncing force. An object with higher Viscosity value tends to keep its shape more. Viscosity - controls the level of impact that a collision will have on the shape of an object.Setting the coefficient to an extremely large value creates stiff motions. Reducing the Spring coefficient creates soft motions, while raising Spring produces motions with a stronger repelling force. Spring - controls the springiness or stiffness of the material.The dress on the right hangs down more due to its weight and also will not flap as much. You can simulate the motions of a heavy material by increasing the Weight value, and you can simulate the motions of a light material by decreasing Weight. Weight - defines the weight of the material. ![]() “Fix” applied to polygons indicated inside orange outlines – these stay in place, while gravity affects the rest of thecloth object. In the image below, the ends of the cloth have been Fixed so that they stay in place while the rest of the geometry is pulled down by gravity.
