Create a Voxel Mesh. Stand on it and do world:Raycast() to the ground in a script. Usually, when you try to reflect a raycast, you can just rotate the direction after hitting the entity and shoot another raycast. On voxelmeshes however, the next ray will always hit the VoxelMesh itself again.

After investigation, it appears that this is a technical limitation related to how we generate the collision data for voxel meshes. Because of this, any Raycast originating from the surface of the mesh will generate a hit on that surface.
The best I can offer is the following mitigation options:
Add the voxel mesh from your initial hit to your reflected raycast: GetWorld():Raycast(start, end, hitResult.entity, ...)
This is quite limiting, as it prevents hitting some other part of the same voxel mesh, but depending on what you’re looking for, it might be sufficient.
Offset the start of your reflected Raycast by a tiny amount using the normal from your initial hit: GetWorld():Raycast(start + 0.001 * hitResult:GetNormal(), end, ...)
This admitedly feels a bit hacky, but seems to work in all my test scenarios.
