The method to use for updating to a new skin. Use the Update From SOP button below to initiate the update.

The UV Attribute to use when Method is set to Transfer By UV.

Update to a new skin geometry, using the options set above. This let’s you pick a SOP to use as the new geometry.

The bounding box controls let you specify a bounding box for the referenced geometry. Only when this bounding box is "on screen" will mantra load the referenced geometry. You can set Bounding box to No bounding box required, in which case mantra will always load the references geometry regardless. You can also specify the bounding box by referencing the SOP’s bounding box in the SOP Bounds parameter.

The geometry whose bounding box you want to reference.

The minimum bounding box dimensions, when setting explicit bounds.

The maximum bounding box dimensions, when setting explicit bounds.

Allows you to adjust the bounds of the bounding box to compensate for any fur that may have been moved outside of the original bounds by a shader.

The categories defining the set membership of this object.

Space-separated list of objects to appear in reflections on this object. You can use wildcards (for example, prop_*) and bundle references to specify objects.

You can also use the link editor pane to edit the relationships between objects using a graphical interface.

Objects that will be refracted on this object.

Space-separated list of names of lights that illuminate this object. You can use wildcards (for example, key_*) and bundle references to specify objects.

You can also use the link editor pane to edit the relationships between lights and objects using a graphical interface.

Render the object as a cut-out matte.

Shade every sample rather than shading micropolygon vertices. This setting enables the raytrace rendering engine on a per-object basis.

If enabled, this object’s rendered motion blur will be based upon the vector attribute named v in the geometry. The units of the attribute are in (1 unit/sec).

Velocity motion blur should be used if it contains changing point counts since it cannot be rendered correctly with deformation motion blur. For example, a particle system with changing particle counts should use this option.

You can use Velocity blur on these types of objects as long as they have valid v attributes. Particles automatically have the v attribute so if you are rendering particles, simply enable this parameter.

Shading Quality is used by micropolygon rendering to control the shading resolution. A value of 1 means that approximately 1 micropolygon will be used per pixel. A higher value will generate smaller micropolygons meaning more shading and sampling will occur, but the quality will be higher.

Ray Shading Quality is used by raytracing when rendering. When raytracing subdivision surfaces or patch surfaces (eg. NURBS), geometry dicing will occur similar to micropolygon rendering. This value functions similar to Shading Quality for these primitives when raytracing.

Geometry Filter Width sets a minimum rendering width in raster space for curves. Any curve segment smaller than this value at the projected point will instead have its opacity scaled down as a ratio of the minimum width and the actual width. This helps rendering very thin curves without having to adversely increase the pixel samples to compensate.

This property controls the tessellation levels for nearly flat primitives. By increasing the value, more primitives will be considered flat and will be sub-divided less.

This property will cause this object to generate all the micro-polygons before the render begins. Ray tracing can be significantly faster at the cost of potentially huge memory requirements.

When rendering a curve, turns the curve into a surface and dices the surface, running the surface shader on multiple points across the surface. This may be useful when the curves become curved surfaces, but is less efficient. The default is to simply run the shader on the points of the curve and duplicate those shaded points across the created surface.

If enabled, geometry that are facing away from the camera are not rendered.

If enabled, polygon geometry rendered from this object will be rendered as a subdivision surface.

By default, points within particle system primitives are rendered as sphere primitives. If a point is not part of a particle system primitive, then it is not rendered. If this parameter is enabled, then all points (regardless if they are part of a particle system) from this object’s geometry will be rendered as point (circle) primitives facing the camera plane.

Coving is the process of filling cracks in diced geometry at render time, where different levels of dicing side-by-side create gaps at T-junctions.

The default setting, Coving for displacement/sub-d, only does coving for surfaces with a displacement shader and subdivision surfaces, where the displacement of points can potentially create large cracks. This is sufficient for more rendering, however you may want to use Coving for all primitives if you are using a very low shading rate or see cracks in the alpha of the rendered image.

Do not use Disable coving. It has no performance benefit, and may actually harm performance since Houdini has to render any geometry visible through the crack.

This setting only applies to micropolygon rendering.

If enabled, smooth normals will we computed at render time if the normal (N) vector attribute does not exist.
