- Opacity - to control the overall opacity of the object
- Back culling - to hide back facing polygons from the camera
- Hidden from... - which can hide the object itself from the camera, and/or its influence in the scenes GI and lighting
- Boolean - lets you designate the object as a "cutting object" to hide parts of other objects. Similar to Z-clip camera planes but independent of the camera. Exclusive More information in the Render booleans page.
- Blockable emitters - lets you specify an emitter that will only affect this object and nothing else in the scene. More information in the Blockable emitters page.
Opacity
This object parameter lets you control the objects overall opacity, with a 0-100% range. It can be very useful for illustrative renders - for example to show individual gears inside a watch, while still showing a hint of the cover. If you are using a plugin, this value can also be animated to create interesting reveal animations.

Z-clip Planes define near and far distance boundaries outside of which the objects will not be considered by the render calculations. Please see the Z-clip planes page for more details.
Boolean
This object property lets you specify an objects bounding box/bounding sphere, or plane as a cutting object in your scene. Any objects inside the cutting objects bounding box/sphere, or behind the specified plane will be rendered as if it was hidden from the camera, just as with the Z-clip feature of the cameras. The two big advantages compared to z-clip of course is that you can freely move the camera without affecting what gets clipped, and also that you can create different sizes and shapes to act as clipping shapes.
Bounding box
This option takes the bounding box size of the object and uses it as the cutting shape.
Bounding sphere
This option takes the bounding sphere size of the object and uses it as the cutting shape.
Planes
This option is easiest to use if the geometry is already a plane. It will make everything in the negative direction of the chosen local axis (XY, YZ, ZX), hidden to the camera. You can rotate the object to decide which way the negative axis is pointing.
