Can LOD (Level of Detail) systems cause issues with grass error registration? If so, how can they be avoided?

Yes, LOD systems can introduce errors. Switching between different LOD levels can cause grass blades to abruptly change position or orientation, creating noticeable pops or discontinuities. To avoid this: 1) Use smooth transitions between LOD levels (e.g., alpha blending). 2) Ensure consistent pivot points across LOD levels. 3) Consider pre-baking the grass motion into the LOD meshes or textures to avoid recalculation during LOD transitions. 4) Use consistent registration techniques for all LOD levels.
