Some of the more complicated components of RockPlot3D displays (isosurfaces, grid surfaces, etc.) have lots of options for adjusting colors, filtering data, and more. These are discussed earlier in this section.
Some components of the displays are quite simple – they contain only a general transparency setting.
Any time that you see the Group symbol 
in the RockPlot3D data listing, you know that there are one or more data items contained within it. You can expand the group to see the individual data items, and you can adjust them individually as discussed in this section of the documentation.
You can also adjust the transparency of the entire group by following these steps.
- Right-click on the name of the group to be modified (in the data pane of RockPlot3D), and choose Options. You can also double-click on the group to access the settings.
- Type in or use the up- or down-arrow button to set the percent opacity for all of the items contained in the group. At a setting of 100, everything will be 100% opaque. At a setting of 50, everything will be 50% opaque.
- Click the Apply button at any time to view the effect of your transparency changes on the items in the group. You may need to drag the Options window out of the way to view the display. You do not need to close the Transparency Options window to apply and see the changes.
! Using the Apply button tells the program to invoke the changes you have made. You cannot discard changes once they have been applied.
- You can repeat this process for additional groups or individual items, without even closing the current Transparency Options window. Just double-click on another item and its Options window will be docked with the others.
The setting you establish for the group will override any transparency setting already established for individual item(s) in the group.
If you now change the transparency setting for any individual item in the group, the change will affect that data item only, not the entire group.
There are many types of data items that can be displayed in RockPlot3D that contain a single, simple setting: transparency adjustment. This would include floating bitmaps 
, draped bitmaps 
, storage tanks 
, polylines 
, down to the triangles 
that comprise oriented objects and stratigraphic thickness diagrams.
- Right-click on the name of the item to be modified (in the data pane of RockPlot3D), and choose Options. You can also double-click on the item to access the settings.
- Type in or use the up- or down-arrow button to set the percent opacity for the item. At a setting of 100, it will be 100% opaque. At a setting of 50, it will be 50% opaque.
- Click the Apply button at any time to view the effect of your transparency changes on the item. You may need to drag the Options window out of the way to view the display. You do not need to close the Transparency Options window to apply and see the changes.
! Using the Apply button tells the program to invoke the changes you have made. You cannot discard changes once they have been applied.
- You can repeat this process for additional items, without even closing the current Transparency Options window. Just double-click on another item and its Options window will be docked with the others.
