and used to accelerate rendering. |

| 677 |
+ |
You cannot run more than one |
| 678 |
+ |
.I rad |
| 679 |
+ |
process at a time on the same input file, |
| 680 |
+ |
as the second process will attempt to recover the output files |
| 681 |
+ |
of the first process, damaging the results. |
| 682 |
+ |
The exceptions to this are running interactively via the |
| 683 |
+ |
.I \-o |
| 684 |
+ |
option, or rendering different views using the |
| 685 |
+ |
.I \-v |
| 686 |
+ |
option. |

|
Incremental building of octrees is not supported as it would add |
| 689 |
|
considerable complexity to |
| 690 |
|
.I rad. |
| 721 |
|
The use of upper and lower case naming for the standard views may be |
| 722 |
|
problematic on systems that don't distinguish case in filenames. |
