Describe the bug
When fastnoise3d is changed from opensimplex2 to cellular, no terrain is generated

To Reproduce
Steps to reproduce the behavior:

1. Create VoxelLodTerrain
2. Set generator as VoxelGeneratorGraph
3. Add the fastnoise3d node
4. Link it with x, y, z
5. Regenerate terrain
6. Now select the fastnoise3d in the voxel graph and change the noise from opensimplex2 to cellular
7. Regenerate
8. See error

Expected behavior
Cellular terrain to generate as seen when using cellular generator
