Troubleshooting
If raytracing nodes are hatched out in red, it means that raytracing is disabled on the root.
 |
We do not recommend enabling antialiasing on the root node as it tends to make raytracing slower and use a lot more memory.
For more efficient antialiasing, enable Full-Screen Antialiasing on the RT Refinement node as well as using Temporal or FXAA antialias nodes.
