Mapping Template

Mapping Template adds mappable parameters, with the same map button as the shipped nodes, to an HDA you build. Experimental, hidden from the Tab menu.

Mapping Template adds mappable parameters to a Houdini Digital Asset you build, so they get the same map button as the parameters on a Grow and can be driven by maps. Effector Template does the same for an effector stack.

Make Your Own Tools says how to place it.

Using it

Put it inside your HDA. Target HDA is .. by default, the HDA it sits in.

Add a row under Mappable Parameters for each parameter. Name is the parameter's name (its label is made from it), Value its default, and Folder the folder it goes in on the target; a folder that doesn't exist is created. Rows with Enable off are skipped.

Promote to Target asks for a shape and saves the HDA:

Create Parms adds each parameter as a value with its map button, and links the template's rows to them.
Create Multiparm adds each as a list the artist can add entries to.
Create Multiparm (Named) does the same, with a Name field on each entry.

Promoting again replaces parameters of the same name.

New Maps Read From sets whether a map made from these parameters starts reading Self or Parent. Decorations use Parent, the tree where the part sits.

The Template folder holds the VEX header and footer the template generates code from.

Status

Mapping Template is experimental, and hidden from the Tab menu in 0.7.3.

Map Random

Map Random gives each element its own stable random value between Min and Max, shaped by a ramp. Experimental.

Noise Effector

Noise Effector is a direction that changes smoothly through space, for irregularity without per-point jitter. Experimental.
