The direct answer
What to do first
Choose Corona or V-Ray by the renderer already used by the project and by the materials, lights, and plugins your scene depends on. Both have broad 3ds Max workflows, but renderer-specific materials and maps still need a test; do not assume a scene transfers perfectly between them.
Begin with the existing scene
If the project already has a renderer, staying with it usually reduces material and lighting conversion work. Start by listing the scene's critical dependencies: materials, maps, lights, camera effects, proxies, and any plugins.
Then test one representative asset in the same renderer and version as the final scene. A still image from another renderer is a visual reference, not a compatibility test.
Corona: CPU-first interior workflow
Chaos documents Corona as CPU based and lists interior-friendly tools such as interactive rendering, LightMix, denoising, Corona materials and lights, and common 3ds Max maps. Choose it when the scene is already built around Corona materials and the team's 3ds Max workflow.
Chaos documents compatibility considerations for V-Ray assets inside Corona's supported-feature guidance. Treat that as a conversion clue, not a promise that a scene will look identical.
V-Ray: CPU and GPU paths to verify
Chaos documents V-Ray for 3ds Max as supporting many standard 3ds Max features and third-party plugins, while also listing features that are unsupported or only partially supported. V-Ray's documented product materials cover both CPU and GPU rendering paths, so verify the scene's required features against the exact V-Ray version and device setup.
Its materials documentation describes V-Ray-specific materials and textures inside the 3ds Max Material Editor. A standard geometry import may be straightforward while a renderer-specific material still needs conversion or replacement.
Choose the lowest-risk test path
Compare one asset under the intended renderer: import, relink textures, check roughness and normal response, place a camera, and make a small test render. Note what required manual work and how the result compares with the source preview.
Choose Corona when a CPU-first Corona scene and its material ecosystem are already established. Choose V-Ray when the team needs its CPU/GPU options or V-Ray material pipeline. In either case, test the actual scene because renderer conversion is a scene change, not a file-extension change.
| Question | Corona | V-Ray |
|---|---|---|
| Render path | CPU-based renderer documented for 3ds Max. | CPU and GPU paths documented for 3ds Max; verify feature coverage. |
| Material workflow | Corona materials, lights, and common 3ds Max maps. | V-Ray-specific materials and textures in the Material Editor. |
| Choose when | The existing scene and team already use Corona. | The team needs V-Ray's established material or CPU/GPU path. |
Keep this beside the project
A short checklist
- The project's renderer and version are known.
- Critical materials, maps, lights, and plugins are listed.
- One representative model was tested in the target renderer.
- Renderer-specific materials were inspected after import.
- Texture relinking and a small test render succeeded.
