Description

Raytraced reflections contain aliasing, but the reflections of the aliased reflection do not. In the provided image, you will see plane C shows the reflection of the grid material with aliasing artifacts(A) and plane B shows the reflection of C, which does not contain the aliasing artifacts

Steps to Reproduce
  1. Download and open the attached project
  2. Observe the reflection in the wall and floor planes with the assigned mirror material.

 

Result: The grid material reflected in the floor plane contains aliasing, while the reflection of the floor is properly reflected in the wall without aliasing.

 

Expected: No aliasing visible in the floor's reflection of the grid material
