Some new features in MODO 10 to help simplify the workflow with game engines. This feature looks very cool :
Streamlined export to games engines – Now you can transfer assets between MODO and Unity or Unreal Editor 4 with shading information intact, eliminating the need to recreate shading work in the games engine editor. What’s more, exporting to games engines is now single-step operation, thanks to a new preset mechanism with ready-made presets for Unreal and Unity, and the ability to create custom presets to target additional engines. In addition meshes are now automatically triangulated on FBX export—matching MODO’s internal triangulation for GL rendering and ensuring a visual match—and there’s now direct support for a range of common DDS image formats.
or this :
Real-time content creation workflows – MODO 10 offers workflows specifically targeted at artists creating content for real-time applications. The Games Tools layout is centered around the everyday tasks of vertex normal editing, texture baking and exporting to game engines, while still providing quick access to modeling tools. In addition, you can now navigate through your MODO scene as you would a video game level, with a new FPS (First Person Shooter) mode that uses the mouse to look around, and the keyboard to move—enabling you to evaluate your scene as a player would see it.
