When using the ray tracing primary rays debug mode, there is a lighting artifact based on camera height.
I was wondering if anyone knows what causes this? I am using a modified engine using only ray tracing, and I am trying to resolve this lighting problem. It doesn’t occur when the full pipeline is applied, only when primary rays is used - it could possibly be something in the material applied to the terrain.
To recreate, simply load in any terrain from cesium in a blank level
and select view mode → ray tracing debug → ray tracing primary rays.
Then, move around the scene, and you should encounter the following:
As you can see, as the camera lowers the lighting artifact appears, and it follows the camera when you move left and right.
