| To figure out if a level has fog or not, you will have to look at any [[super_mario_64:fast3d_display_list_commands#b7f3d_setgeometrymode|0xB7 (F3D_SETGEOMETRYMODE)]] commands that you see before a 0xFC command occurs. If the parameters contain a 0x10000 flag, then fog will be enabled in the level. | To figure out if a level has fog or not, you will have to look at any [[super_mario_64:fast3d_display_list_commands#b7f3d_setgeometrymode|0xB7 (F3D_SETGEOMETRYMODE)]] commands that you see before a 0xFC command occurs.

| + | ==== Issue with Fog and Billboarded Objects ==== | ||
| + | |||
| + | Levels imported in SM64 Editor using fog with transparent textures, have an issue where sprite-based objects like coins, chuckyas, and goombas would be covered with the fog color. This is an example on a "SM64: Ztar Attack" affected level: | ||
| + | |||
| + | {{:super_mario_64:ztarattackfogissue.png?nolink&400|}} | ||
| + | |||
| + | This problem came from a typo in the display list that SM64 Editor creates when importing the level. This happens on levels with fog that has alpha textures. Levels with fog without alpha textures aren't affected. | ||
| + | |||
| + | The typo is near the end of a display list where it is disabling fog. \\ | ||
| + | The SETOTHERMODE_L command was set to ''B9 00 03 1D <color #ed1c24>C8 11</color> 30 78'' instead of ''B9 00 03 1D <color #ed1c24>00 44</color> 30 78''. | ||
| + | |||
| + | **How to fix it?** | ||
| + | 1.) Find all occurrences of: | ||
| + | BA 00 14 02 00 00 00 00 | ||
| + | B9 00 03 1D C8 11 30 78 | ||
| + | B6 00 00 00 00 01 00 00 | ||
| + | | ||
| + | 2.) Replace occurrence with: | ||
| + | BA 00 14 02 00 00 00 00 | ||
| + | B9 00 03 1D 00 44 30 78 | ||
