Introduction

OmniStep is a Blender add-on that provides a scriptable first-person controller. It is an interactive animation and prototyping tool, offering a built-in game loop and optional scripting for more complex interactions.

Why this Exists

I always wanted to be able to walk and fly through my Blender scenes, experiencing them the same way I would be able to in a game engine. While Blender has its basic 'Walk Navigation' feature, it is far from what I had in mind - so I wrote OmniStep.

What It Can Do

OmniStep is a highly customizable and scriptable first-person controller comparable to AAA games in terms of movement mechanics, collision response, and input handling. With its ability to record movement and player actions, it can be used to create shots that would otherwise involve a lot of manual animation work. This includes walkthroughs and extremely smooth fly-throughs.

With its walk and fly modes, a smart collision system, spawn points, and scripting support, it simplifies level prototyping, making Blender an even more versatile tool for game development and provides artists with an intuitive new way to experience their works.

- Utilizes a BVH-tree, capable of handling millions of triangles
- Supports instanced collection and linked library collision
- Selective inclusion or exclusion of collections
- Partial dynamic collisions using the scripting module
- Prevents endless falling by reusing last ground contact
Recording

- Loop recording
- Buffered recording (recording without timeline playback)
Scripting
- Add new functionality through user-written scripts
- Exposed game loop method
- Automatically expose parameters in UI panels
- Access to player parameters and the collision system
Customizable Settings
- Input smoothing options
- Customizable keymaps and Gamepad mappings
- Gamepad support for Windows (XInput)
- Mouse settings including sensitivity and invert Y-axis
- Custom N-panel placement
- Framerate independence with support for 120+ Hz
- Choice of scale settings: metric, imperial, and free
Additional Features

Requirements

OmniStep supports all platforms and Blender versions from 3.6 up to the current 4.2.1 It has been tested on macOS and Windows.

Add-on Compliance
This add-on is fully self-contained, does not include any external libraries, does not directly interact with the file-system and operates entirely offline. It does not register with any application handlers and does not leave behind any residual data in the Blender scene, except for its settings configuration. The sidebar panel can be optionally nested under the 'Tool' tab to maintain a clean UI.
