This operator negates the incoming integer, float, vector or vector4 value.
It represents a simpler version of the Multiply Constant operator because it does not perform a multiplication by -1.
The following examples include this node.
This example demonstrates how a mixture of fluid colours can have their colour changed by a collision with a static object.
This example demonstrates how to diffuse the density of a smoke simulation using the Gas Diffuse DOP.
This example simulates grass being pushed down by an RBD object. Fur Objects are used to represent the blades of grass and Wire Objects are used to simulate the motion. When a single Fur Object is used to represent the grass, neighbouring blades of grass will have similar motion. Additional objects with different stiffness values can be used to make the motion less uniform. When "Complex Mode" is enabled, two objects are used to represent the grass. The stiffness of each set of curves can be controlled by adjusting the "Angular Spring Constant" and "Linear Spring Constant" parameters on the corresponding Wire Objects.
This example shows how to setup the Bake Volume SOP to compute the lightfield created by the shadowing of a fog volume. It then exports the fields properly to be rendered in Mantra by a constant volume shader.
This example demonstrates how the Fur SOP and Mantra Fur Procedural can be applied to an animated skin geometry. CVEX shaders are used to apply a custom look to the hairs based upon attributes assigned to the geometry.
This example illustrates how custom shaders can be used to define the appearance of fur generated by the Fur SOP.
This example demonstrates how to use a Points From Volume SOP to create a target goal for a flip simulation and make it fill a given piece of geometry.
