Guide to sequenced textures in LEGO Rock Raiders

Sequenced textures are frequently used in LEGO Rock Raiders for steam effects

This modding guide for the 1999 video game LEGO Rock Raiders details how to add sequenced textures to models in the game.

What are sequenced textures?

In the Windows version of LEGO Rock Raiders, sequenced textures are textures that are animated in-game using a series of bitmap files. Sequenced textures can be used in any object that uses LightWave Scene files for animations: all entries in the MiniFigure, Building, Vehicle, and Creature/RockMonster types, but not in the Upgrade types or WorldTextures. Certain MiscObjects entries support animations, such as Barriers and Sonic Blasters, while others do not, such as Energy Crystals and Ore. In the original game they are mostly used only for particle effects, such as steam and dust.

Using LightWave 3D 5

This section of the guide details how to create a sequenced texture using LightWave 3D 5. Version 5 was first released in 1995 and was updated to version 5.5 in 1997 and version 5.6 in 1998; one or both of the latter two versions are likely the ones used in the development of LEGO Rock Raiders. For this guide LightWave 3D 5.6 is being used; this version will still run on Windows 10, but users may find its interface difficult compared to later versions. The LightWave file formats changed starting in version 6; these later versions can still save LightWave 5 objects and 5.6 scenes, and can view sequenced textures, but will not properly save sequenced textures in the version 5 LWO format (at least through LW9). To get around this, either save your model without sequenced textures and then load it into LightWave 5, or follow the hex editing section below.
