Chaos Arena vs SMODE

Chaos Arena is a Windows solution for real-time ray tracing and in-camera visual effects on virtual production stages. It moves 3D content to LED walls without preprocessing and supports carrying assets from pre-production through post-production. Arena renders global illumination, reflections, refractions, and shadows with real-time path tracing, plus single-pass rendering. Artists can adjust lights, exposure, assets, and materials during production through its interface and Material Editor. Assets from Maya, Houdini, 3ds Max, and Blender can be used. Camera tracking protocols include FreeD, Vicon, stYpe, OptiTrack, and EZtrack, with tracking data saveable as Alembic. Stage features include distributed rendering, dual-GPU rendering, and Genlock through NVIDIA Quadro Sync. Arena supports ACEScg, HDR, OpenColorIO, USD, MaterialX, real-time depth of field, lens encoders, regional decal color correction, and ray-traced Gaussian Splats. Chaos says one GPU can render a quarter of a trillion polygons at 60 fps. The product is described as out of beta and production-ready. Pricing is available by contacting Chaos for a quote or demo.

SMODE is a Windows platform for real-time visual compositing and media serving at shows and installations. It combines 2D and 3D compositing with video mapping, stage simulation, animation, and video export. Smode Live adds playback and editing tools for live operation, with support for DMX, Art-Net, sACN, LTC/MTC inputs, and people tracking systems. It can capture or output video through Deltacast and Blackmagic cards. The Community edition lists ISF and ShaderToy shaders, Substance, Python scripting, MIDI, OSC, NDI, and Spout integrations; camera tracking, LED-stage and greenscreen workflows, and live compositing are also supported. The free Community license is non-commercial and includes Full HD input, output, content, and export without watermarks. Smode Compose FHD costs €300 a year, excluding VAT, and includes commercial use and 4K video export. The FAQ specifies Microsoft 64-bit operating systems, at least Windows 10 version 18h3, and says licensing is not designed for virtual machines.
