Games include models of people, monsters, cars and so forth. These models are almost universally created using a third party tool. Models normally consist of a polygon mesh that specifies the structure of the model, textures which are layered over the polygon mesh and animations. Animations specify standard motions that the object can perform, such as laughing, waving, running and so forth.
In theory, it is possible to specify models and their animations directly in Ogre, but this would be so time-consuming that people use third party modeling tools instead.
Modeling tools use proprietary formats for the models they generate. However, many tools provide a plug-in capability, allowing them to be extended to provide output in the format that Ogre expects.
- 3ds Max: Windows only; commercial. Among survey respondents, 3ds Max was the unanimous choice of commercial tool for object modeling with Ogre.
- AC3D: Windows, Mac, Linux. Commercial but cheap at $59.95. Good for static mesh modelling, doesn’t support animation.
- Blender: Windows, Mac, *nix; free under GPL. Blender is an open source modeling tool, with many advanced features and a very active and dedicated community. The GUI needs getting used to, but lends itself to a very efficient work style once learned. The Blender Tools page describes the many tools available for incorporating blender into your Ogre content creation process.
- Maya: ‘Windows, Mac, *nix; commercial.’’
- MilkShape: Windows only; commercial but very cheap. MilkShape is quite straight-forward to use, and supports polygon modeling, texturing and skeletal animation. At time of writing, MilkShape is offered under a $25 shareware license.

Worlds normally consist of exterior terrain populated with entities (trees, houses, monsters, etc.), water, sky and light sources. Very broadly speaking, there are two problems in creating worlds: creating the terrain, and populating the terrain with all those other things (entities, water, sky, light sources.) World design tools help to solve these problems. Some tools deal exclusively with terrain generation, while others help with laying out the scene.
- Terragen: Windows, Mac; Free for non-commercial use until v1.0 released. Permits development of gorgeous terrains. Terrains can be read in using the Terrain Scene Manager.
- Leveller: Windows; Commercial. Heightfield modeler with a simple interface and a number of useful plug-ins. At time of writing, $99 for a license. Free demo available.

- Terrain Generator: Windows, Freeware. Terrain Generator is an intuitive and flexible terrain generator, which allows users a 3D control over the map (as opposed to a painting style 2D editor). While capable of exporting heightmaps, it is unclear as to whether the textures can be exported alongside the heightmap. However, it can export to a number of other formats including .vmf, .map, .rmf, .t3d, .obj and some others, so exporting textures may be possible by means of exporting through a different program.

- TerraNoise Windows, Free Procedual fractal generation based on libnoise.

Using exporters available for the following programs allows for export to a scene format known as DotScene. This can be efficiently optimized using the DotSceneOctree scene manager, and lends itself well to large outdoor areas.
- 3ds Max: Windows only; commercial. Among survey respondents, 3ds Max was the unanimous choice of commercial tool for object modeling with Ogre. The Yake Octopus exporter allows for easy DotScene export.
- Tools: Blender: Windows, Mac, *nix; free under GPL. Blender is an open source modeling tool, with many advanced features and a very active and dedicated community.

- Glue Editor - Real-time scene editor with a simple user interface designed specifically for Ogre projects
The term level is normally used to describe the interiors of building, dungeons or industrial complexes in which many games take place. Levels are different from exteriors in that they typically consist of regular geometry (hallways, staircases, etc.) rather than terrain. Level design tools typically allow the definition of the level’s geometry as well as the placement of entities (furniture, monsters, etc.) and light sources.
While levels can be displayed in any scene manager, Ogre provides the BSP scene manager which employs BSP culling and collision management to render levels efficiently. This scene manager is no longer subject to legal restrictions since the release of GTKRadiant and q3map2 under the GNU GPL by id Software. BSP levels are generated from Quake .map files, created via a map editor.
- 3ds Max: Windows only; commercial. For those who can afford it, 3ds Max can be used to edit levels. The Octopus plugin can be used to make 3ds Max more Ogre-friendly. Exported levels are rendered at runtime with the DotScene scene manager.
- Blender: Windows, Mac, *nix; free under GPL. Blender is a free modeling tool, with many advanced features and a very active and dedicated community. The GUI need getting used to, but lends itself to a very efficient work style once learned. A scene exporter is available as addon project.
- GtkRadiant: Windows, Linux, MacOS X; free under the GNU GPL. The level data can be created with this editor and must be compiled with a BSP compiler (such as q3map2) to be used by the BSP scene manager. The q3map2 BSP compiler does support lightmaps generation.
- Maya: Windows, Mac, *nix; commercial. For those who can afford it, Maya can be used to edit levels. The LFA Scene Manager MEL scripts can be used to make Maya more Ogre-friendly. Exported levels are rendered at runtime with the DotScene scene manager.
- Quake Army Knife (QuArK): Windows; GPL License. QuArK is another Quake 3-format level editor. Levels are generated in .map format, which must be compiled to BSP for use in the BSP scene manager.
- Worldcraft/Hammer: Windows; Only to develop new levels for Half-Life and other compatible Valve products. Hammer (called WorldCraft prior to 3.0) was developed as a modding tool for the Quake and Half-Life games. Licensing of Hammer prevents its general use, though I believe the restrictions on earlier versions were weaker (unable to find references at the moment, though I believe WorldCraft was purchased by Valve and renamed to Hammer). WorldCraft generates MAP models which must be compiled to BSP form for use in the BSP scene manager.
- DeleD is a 3D modeler leaned toward interior level creation. It has a free Lite version and a low cost Pro version. Easy to get the hang of and has a free Ogre exporter plugin that works well.

- Giles: Freeware Gile[s] is a Global Illumination Editor. It allows you to create a radiosity lightmap for a scene. A lightmap is another texture layer, that adds light and/or shadow to the underlying texture. The radiosity lighting technique is far superior compared to any real-time technique. A Gile[s] plugin that allows exporting Ogre meshes and materials (contributed by Walaber) is available as source in the ogreaddons and as a binary distribution on his homepage.
