VRay and Renderzone in V-Ray | form•Z Posted October 9, 2018 The texture map controls (placement, scale etc) are formZ parameters so they are used by both RenderZone and V-Ray for formZ (and shaded work/full of course). Renderzone inherits the the basic material parameters (diffuse color, diffuse texture map, bump map etc) from V-Ray materials. Materials that use these parameters (Generic, Car Paint etc) will appear very similar in Renderzone. If your V-Ray material uses a VRMAT material or other non image based parameters (reflectance, refraction etc), then RenderZone will show a approximation of the material. This works both ways so if you have RenderZone materials, V-Ray will inherit the basic material parameters (diffuse color, diffuse texture map, bump map etc) from RenderZone. Keep in mind that there are many other factors that affect the rendering including lighting, environment, global settings etc that its not realistic to expect the engines to give the same results.
