A scale on the color. If the intensity is 0, the light disabled. The light will only be sent to the renderer if the object is included in the "Force Lights" parameter of the output driver.
Turning this toggle off is equivalent to setting the light intensity to 0.
Enable Light In Viewport
Turning this off removes the light from consideration in the viewport. This is useful for lights which only make sense at render time.
Whether or not this object is displayed in the viewport and rendered. Turn on the checkbox to have Houdini use this parameter, then set the value to 0 to hide the object in the viewport and not render it, or 1 to show and render the object. If the checkbox is off, Houdini ignores the value.
Viewport Selecting Enabled
Object is capable of being picked in the viewport.
Script to run when the object is picked in the viewport. See select scripts .
Cache Object Transform
Caches object transforms once Houdini calculates them. This is especially useful for objects whose world space position is expensive to calculate (such as Sticky objects), and objects at the end of long parenting chains (such as Bones). This option is turned on by default for Sticky and Bone objects.
See the OBJ Caching section of the Houdini Preferences window for how to control the size of the object transform cache.
The following examples include this node.
The Box SOP is used for more than just creating boxes. It can also envelop existing geometry for specific purposes.
The Box SOP can either create a simple six-sided polygon box, calculate the bounding box size for geometry, or be used in conjunction with the Lattice SOP.
There are two objects within the box.hip file that are examples of this:
The animated_bounding_box object shows how you can envelope an object and surround it with a simple box, even if it is animated. This can be useful when displaying complicated geometry, in which case you would put the display flag on the box object and the render flag on the complicated geometry.
This is an example, a Lattice SOP used in conjunction with the Box SOP. The Box SOP is used to envelope some geometry, in this case a sphere. Divisions is checked to create the proper geometry by referencing the number of divisions in the Lattice SOP.
The top points of the box are grouped by a Group SOP. The Spring SOP uses these points as the Fixed Points from which to create the deformation.
Using the Box SOP in this way allows you to change the incoming geometry (the basic_sphere in this case) and have the box and lattice automatically re-size for you.
This example demonstrates how to have multiple shading layers with different uv sets using the Layer SOP and the VEX Layered Surface SHOP.
This example shows the ability of the Particle SOP to define a default Size for any given birthed particle.
A simple Grid can be used to create a dynamic solution of particles streaming off as if blown by the wind. As these particles leave the grid, their size slowly diminishes, as the particle continues to die.
