Overview


The Reflection Filter Render Element stores reflection information calculated from the materials' reflection values in the scene. Surfaces with no reflection values set in its material(s) will contain no information in the render pass and will therefore render as black.

While the VRayRawReflection Render Element gives the full reflection of objects reflecting in the scene, VRayReflectionFilter shows how much of that reflection should come through in the composite. In other words, the filter defines the strength of the reflection, while the raw image defines what is being reflected in the image. When these two elements are multiplied, the true level of reflection is given and produce VRayReflection. Using these component parts of the reflection, you can better fine tune the reflection in your final composite.

The Reflection Filter element is a sub-component in the main Beauty Pass.
