| 1382 |  | Fixed bug that caused incorrect reporting of non-surface in set when | 
| 1383 |  | mixing meshes and instances.  (Thanks to Jack de Valpine for discovery.) |

| 1385 | < | Fixed innacuracy in calculation of diffuse transmission in the presence | 
| 1385 | > | Fixed inaccuracy in calculation of diffuse transmission in the presence | 
| 1386 |  | of pure specular (Fresnel reflection) using "trans" material.  Thanks | 
| 1387 |  | to Christoph Reinhart for pointing out the error. | 
| 1388 |  |  | 
| 1483 |  | could (and did) cause missing segments. | 
| 1484 |  |  | 
| 1485 |  | Added -z option to normtiff to output LZW-compressed files. | 
| 1486 | + |  | 
| 1487 | + | Last change to total causes it to produce results when it sees an empty | 
| 1488 | + | line on the input.  This was not intentional, but I decided I like this | 
| 1489 | + | behavior so I documented it rather than changing it. |

| 1491 | + | ===================== | 
| 1492 | + | Version 3.8 | 
| 1493 | + |  | 
| 1494 | + | Fixed Russian roulette ray termination, which was doing the opposite of | 
| 1495 | + | what it should have been doing, resulting in overestimated values below | 
| 1496 | + | minimum ray sampling weight (serious). | 
| 1497 | + |  | 
| 1498 | + | Changed mksource to use 98th percentile (rather than 99th) for threshold. | 
| 1499 | + |  | 
| 1500 | + | (Above changes included in 3.7.1 patch release.) | 
| 1501 | + |  | 
| 1502 | + | Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF | 
| 1503 | + | does not have STONITS set. | 
| 1504 | + |  | 
| 1505 | + | Fixed bug in ambient calculation that caused black values for multiple | 
| 1506 | + | bounces in some scenes.  Thanks to Mark Stock for creating and sharing | 
| 1507 | + | the sophisticated test scene that demonstrated this problem. | 
| 1508 | + |  | 
| 1509 | + | Fixed bug in antimatter using Russian Roulette sampling. | 
| 1510 | + |  | 
| 1511 | + | (Above changes included in 3.7.2 patch release 22 Aug 2005.) | 
| 1512 | + |  | 
| 1513 | + | Created fieldcomb script to combine alternate fields in a rendering | 
| 1514 | + | sequence.  (Development generously sponsored by Iebele Abel.) | 
| 1515 | + |  | 
| 1516 | + | Added missing preload of mesh objects for more efficient memory use | 
| 1517 | + | during parallel rendering -- this was a serious oversight. | 
| 1518 | + |  | 
| 1519 | + | Created ran2tiff program to automate exposure setting of animation | 
| 1520 | + | sequences using a moving histogram in combination with pcond, and | 
| 1521 | + | converting frames to TIFF. |
