What's the difference between render engines (V-Ray, Corona, D5, Lumion, Enscape)?

A render engine is the software that turns a 3D model into an image. They differ mainly in one trade-off: speed or realism. V-Ray, Corona and Cycles calculate light very precisely and produce the most realistic images, but take longer. Lumion, Enscape and D5 show results in real time, which is faster but less exact.

The main engines

Engine	Type	Strength	Often used with
V-Ray	Path tracing	Top realism, huge control	3ds Max, SketchUp, Rhino, Revit
Corona	Path tracing	Realistic, simpler to set up	3ds Max, Cinema 4D
Cycles	Path tracing	Realistic, free	Blender
D5 Render	Real-time ray tracing	Fast, good interiors	SketchUp, Revit, Rhino
Enscape	Real-time	Live view while designing	SketchUp, Revit, Rhino, ArchiCAD
Lumion	Real-time	Fast scenes, landscapes, animations	Most modelling tools

Path tracing: realism first

These engines trace how light bounces many times around a room. Soft shadows, light through curtains, reflections on stone: all of it comes out naturally. The cost is time, from minutes to hours per image, and more skill to set up. They suit final images for clients, brochures and portfolios.

Real-time: speed first

These engines work like video games: the image updates instantly as you move. They suit design reviews, quick variations, walkthroughs and videos. D5 has narrowed the gap with ray tracing, but in close comparison path-traced images still win on fine detail.

Does the engine matter to a client?

Less than the person using it. A skilled artist with any good engine beats a beginner with the "best" one. What matters is accurate modelling, good materials, natural light and well-chosen camera angles.

What we use

We render with V-Ray and Cycles when realism matters most, and Lumion for fast views. We pick the engine for the project, not the other way round.
