KeyShot vs Terragen

KeyShot Studio is 3D visualization software for product design and CAD data. It renders with real-time ray tracing on CPU, GPU, or both, and includes drag-and-drop materials, a procedural material graph, and an HDRI editor for lighting. Local AI tools provide Restyle, Background, Imagine, Transform, and Replace modes. KeyShot supports native import of 34 3D file formats and LiveLinking plugins, including options for Autodesk 3ds Max, Blender, Cinema 4D, and Autodesk Fusion. Its listed outputs and capabilities include image rendering, a product configurator, an interactive 3D viewer, and augmented reality. Plans are listed for individual designers, freelancers, studios, and larger teams, but several plan prices are not shown. KeyShot Professional is $108.25 a year, billed at $108.25 per user per month annually ($1,299.00 per year); KeyShot Business is $133.25 a year, billed at $133.25 per user per month annually ($1,599.00 per year). A 14-day trial is available, but there is no free plan. Linux support is for Network Rendering only. KeyShot Connect lists access controls, single sign-on, guest access, and an audit log; it is in Early Access with a select group of teams.

Terragen builds, renders, and animates natural environments for landscape visualization, visual effects, and artistic work. It creates procedural and heightfield terrain, can use real-world terrain data, and adds details such as cliffs and overhangs. Its spherical planetary atmosphere model includes volumetric clouds and fog, multiple scattering, and global illumination. The hybrid renderer combines micropolygon rendering and ray tracing, with support for anti-aliasing, motion blur, depth of field, and render elements. Nearly every project parameter can be animated, and image sequences can be rendered through the interface or command line. Terragen imports 3D objects and camera data, exports terrain as heightfields or geometry in formats including TER, EXR, LWO, OBJ, and FBX, and handles camera data in FBX, Nuke CHAN, and Maya MOV formats. It can also generate HDR environments for lighting in other renderers. Windows and macOS are supported, with Linux render-node support. The free edition is for non-commercial use or 30 days of commercial evaluation, with still renders limited to 1280 × 900. Professional subscriptions start at $10 a month.
