When using Live-Link connection, Chaos Vantage can produce different camera exposures than V-Ray VFB in 3ds Max. Here are some examples of what can cause these discrepancies:
- 3ds Max Exposure control added in Environment and Effects window
Currently, Vantage doesn’t support the native 3ds Max exposure settings.
- GI bounces
By default, Vantage has a limit of 2 GI bounces calculated for the scene. For interior rendering, where the scene lighting depends mostly on the GI conditions, this value can be increased to 4, in order to match the lighting result from the VFB.
- Clamp secondary rays
When the default Clamp secondary rays option is enabled, bright secondary (GI/reflection/refraction) rays are suppressed, which usually leads to excessive noise (fireflies). However, when set to low values (less than 200) the scene can turn out to be darker than the actual intended result.
- Color corrections applied in the V-Ray Frame buffer
Added effects or color corrections in the VFB panel can result in a difference between the final image appearance of the Vantage preview and the VFB.
