LuxCoreRender vs Terragen

LuxCoreRender has no write-up on Specifiction yet; its figures are above.

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.
