BlocksmithXR Builder

The future is 3D and our BlocksmithXR Builder is designed from the ground up to give users of all skill levels a means to start creating and sharing their own 3D content.

The Builder

The universal tool for 3D creation.

From the amateur to the professional, anyone can easily and rapidly create 3D art assets and develop virtual reality experiences.

User-friendly design helps you feel right at home

Works on Windows, Mac, and Chromebooks. Designed with a classic desktop UI paradigm, 3D content development is intuitive

Making stuff in VR is not hard

Effortlessly build scenes with simplified 3D positioning, scaling, and rotating with strong alignment features


A model of computer parts in the Builder

250 free models... and counting

The Blocksmith Marketplace holds over 250 free 3D models available for all users. Science, space, buildings, interior, decorations, nature, you name it

It doesn't matter if your model is from Unity or anywhere on the internet.

Build yourself or import .obj files from Unity, Sketchfab, Maya, Blender and many other 3D modelling software products. And from other online resources with 3D models. New: Native Google Poly Integration

It's like building with Legos

Featuring a constructive solid geometry based approach that level designers and modders have embraced for its simplicity and fast results

Animations and Interactions

Want a moving object? Turn on animations and move it around

Animations can be easily applied to any object. Any transformations like scale, rotation, and translation are recorded as the animation path. Make further refinements like loop/randomize and optional ease functions

Your players can do things in your creation

Add interactivity to any situation. Interactive objects can react to touch, sight, animations or player actions. And it is as easy as activating a checkbox

Spin the propeller, not the whole plane

Use nested animations on the sub-model level: animate one or multiple parts of an object independently of other parts


A volcano scene opened in the Builder

Can be viewed with and without headsets

Native Headset & Controller support for Google Cardboard, DayDream, HTC Vive, Samsung Gear VR, Microsoft HoloLens, Windows Desktop, Mac OSX and Web. Quality of experiences scales down for mobile and up for high end platforms. New: ARKit and ARCore support

Performance is critical for VR/AR. We'll tell you where you stand while you design.

Performance Meters look at your scene and use meshes, textures, lights and overall settings to determine how efficient your experience will perform on the various platforms

From desktop to mobile in seconds

Send to your favorite device directly from the Builder to easily test and rapidly develop experiences.

If you hit the limits with us, continue in Unity

Output as a Unity project for further development. Builder scenes convert to Unity scenes, meshes will be combined, texture atlases created, animations & events fully wired up with open source code
