Houdini 17.0 Nodes VOP nodes

Import Attribute VOP node

Imports attribute data from the OP connected to the given input.

This operator imports attribute data from the OP connected to the given input. It returns 1 if successful and 0 if unsuccessful. Possible reasons for failure are:

Specifying the point number is optional.

When using Import Attributes inside POPs, care is required. If one reads from an attribute that is being written to, undefined results can occur. In this case, one should turn on Cache Incoming Geometry at the POP level.

Examples

The following examples include this node.

grass

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.

PopFlow Example for Particle Fluid Solver dynamics node

This example demonstrates how to integrate a POP network with a particle fluid simulation, granting one the Total Artistic Control of POPs with the fluid dynamics of the particle fluid simulator.

BreakWire Example for Wire Solver dynamics node

This example demonstrates how to break wire constraints on a per point basis. The wire solver is set up to constrain certain points if it finds an attribute named 'pintoanimation'.

repeatsmooth

This example uses the foreach sop to apply the same SOP repeatedly to the geometry, accumulating the effect of each pass.

PaintPoints Example for Paint geometry node

This example demonstrates how to paint scattered points onto the surface of your geometry with a set number of points per area.

AlphaOmega Example for Points from Volume geometry node

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.

GroupPainted Example for Add Point to Group VOP node

This example demonstrates how to take a painted attribute and build a point group from that attribute using the Add Point to Group VOP and the Create Point Group VOP.
