Armory3D vs CopperCube

Armory3D is a free, open-source 3D game engine that works as a Blender add-on and external SDK. It targets games for Windows, Linux, macOS, iOS, Android and the web, with visual scripting and Haxe available for game logic. Its scriptable renderer supports deferred and forward paths, and developers can create custom render paths. The engine includes a UI library and editor, physics based on Bullet for rigid and soft body simulation, and an option to use Oimo. Navigation meshes support real-time pathing for objects marked as actors. Effects and animation include emitter and hair particles with GPU instancing, GPU skinning, bones, keyframes, shape keys and tilesheets. Listed lighting features include voxel-based ambient occlusion, lightmapping, area lights, reflection probes and IES textures. The setup guide asks users to install Blender 4.5.x LTS and says Blender 3.3 LTS and earlier are unsupported. The repository identifies the license as zlib/libpng and permits commercial use subject to its stated restrictions. The privacy policy says Armory software does not collect, market or sell user data.

CopperCube is a 3D authoring tool for making games and apps, including projects created without programming. Its maker cites first-person shooters, adventures, walkthroughs, simulators, and e-learning apps as possible uses. A click-based event and action system supports no-code interactions, while JavaScript can be used for scripting across publishing targets. Visual tools include terrain editing, real-time shadows, static lighting, moving vegetation, water rendering, particle effects, and a built-in lightmapper. CopperCube imports 3D formats including FBX, 3DS, OBJ, and X. Projects can be published as Windows apps, WebGL websites, macOS apps, and Android apps, although Android publishing is marked deprecated. The current editor is Windows-only starting with version 6.4; a macOS editor download is available for version 6.3. The free edition permits unlimited scenes and apps without royalties or a revenue limit. Professional costs €37, paid once, and Studio costs €126, paid once. The maker says projects made with any edition can be published and sold without royalties.
