Modelling – Operation Flashpoint Category

Introduction

Operation Flashpoint has a wide range of vehicles and other models available in game, however many fans wanted to expand the OFP experience with different aspects of war and other fun modifications. Bohemia Interactive responded and have created their own modelling tools called Oxygen Light (or O² for short), and a model previewer called Oxygen Viewer often refered to as Buldozer.

If you are looking to learn modelling in OFP then you can view some tutorial's and example models on the Breathe page.

Basic information

Model detail in Operation Flashpoint has practically no limits, but for the sake of making your fps counter display at least two digits, staying under 5000 polygons is advisable.

No model in OFP can have more then 32767 faces or 32767 vertices. Vertices somewhat correspond to O2 points, but there are usually more vertices than points due to different UV mapping or normals.

Flashpoint uses a "LOD" (Level of Detail) system. This comes down to units at larger range having less detailed models. The LODs have to be created manually. Lods are also used for other purposes, such as identifying solid mass, walkable areas, hitzones, shadow, and more.

Flashpoint uses textures that are *^² , such as 32, 64, 128... up to 4096. Commonly, 512 and 1024 textures are used. An addonmaker should attempt to use as few textures as possible.

Note: a texture of 512X1024 has a texture ratio of 2 ( 2X512=1024). If the texture ratio gets above 8, chances are that Operation Flashpoint will have troubles dealing with this texture. This is still under investigation after Dedicated servers crashed after using an addon wich contained such a texture.
