Version 1.1 Released!

Introduction

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

Ease of Use

It works out of the box without requiring complex setups for collision geometry. Just set your view and press 'Start OmniStep' to be dropped directly into your scene, ready to explore. Enter a camera view, enable animation recording, and you're all set to film your first walkthrough!

No scripting knowledge is necessary - OmniStep works as is, though scripting is a powerful option for those looking to extend its capabilities.

What It Can Do

OmniStep is a highly customizable, scriptable first-person controller with movement mechanics, collision response, and input handling on par with AAA games. It allows you to record movements and actions, creating walkthroughs and fly-throughs that would otherwise require a lot of manual animation work.

With walk and fly modes, a smart collision system, spawn points, and scripting support, OmniStep streamlines scene exploration, animation prototyping, and level design. It expands Blender’s versatility for both game development and animation, offering artists a new way to experience and interact with their creations.

Requirements

OmniStep supports all platforms and Blender versions from 3.6 up to the current 4.2.2 It has been tested on macOS, Linux and Windows.

Limitations

The collision system is tailored for static geometry and uses an underlying BVH-tree (Bounding Volume Hierarchy) for better performance in heavy scenes. This allows OmniStep to handle collisions with millions of triangles in real-time, but it comes with a trade-off: it does not support animated geometry by default. Animated objects can be excluded to avoid 'ghost' collisions.
Using the scripting module, dynamic collisions can be enabled on dedicated object.

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.
