The short version

  • Each has a real cost: O3DE minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2; Tilt Brush no longer actively developed by Google since January 2021; future updates and support are not guaranteed
  • They diverge on capability: O3DE covers 3D graphics rendering, Tilt Brush covers 3D painting.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

O3DE

  • Minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2
  • Raytracing features require Shader Model 6.3
  • Disk space required is 40 GB using the prebuilt installer and 100 GB or more when building from source
  • Building the engine from source needs 2 GB of RAM per build thread on top of normal system requirements
  • On Windows the editor requires Windows 10 version 20H2 or later plus Visual Studio 2019 16.11.x, 2022 17.3.x or 2026 18.0.x with the Game development with C++ workload
  • The only primary Linux distribution for the editor is Ubuntu 22.04 LTS, and Ubuntu on 64-bit ARMv8 is experimental
  • Linux builds need CMake 3.30.0 or later, which is newer than the 3.22 shipped by default with Ubuntu 22.04
  • Wayland support is experimental, requires building from source, and is limited to the Game Launcher with no editor support until O3DE moves to Qt6
  • Linux requires a long list of additional apt library packages to be installed before building

Tilt Brush

  • No longer actively developed by Google since January 2021; future updates and support are not guaranteed
  • Limited editing capabilities with no layers system and no 3D brushes for precise refinement
  • Not designed for professional branding or marketing work; better suited for creative expression than practical design
  • Tool limitations make it difficult to move, cut, or rearrange grouped elements after creation
  • VR hardware costs are high relative to software cost, and can cause motion sickness in some users

Source
Tilt Brush: Can I export my Tilt Brush creations?

Yes. Tilt Brush creations can be exported as room-scale VR pieces or animated GIFs to share with others. The app does not support direct export to 3D model formats like OBJ or FBX.

Source
Tilt Brush: Is Tilt Brush good for professional 3D design work?

Tilt Brush is primarily a creative expression and painting tool rather than a professional 3D design tool. It lacks features like layers, editable 3D brushes, and precise refinement controls needed for professional workflows. For professional VR sculpting, Adobe Medium or Quill are better choices.
