Since has been a long standing bug since far shadow cascades were introduced in the main UE4 branch and I haven’t gotten a response since I first mentioned it months ago, I figure it may help to actually show what the problem is. is a bug -only- present in the VXGI build, the main branch doesn’t seem to have problem:

Text version:
If you have more than 4 shadow cascades of any type, the ones closest to the camera stop rendering.
4 standard cascades = normal
4 standard + 2 far = the two closest to the camera vanish
4 standard + 1 far = the one closest to the camera vanishes
3 standard + 1 far = normal
4 standard + 4 far = no normal shadow cascades render
4 standard + distance field shadows = the cascade closest to the camera vanishes
3 standard + 1 far + distance field shadows = the cascade closest to the camera vanishes
2 standard + 1 far + distance field shadows = normal
