Glitchy lighting for volumetric clouds I'm new to Blender and followed a tutorial I found online https://www.youtube.com/watch?v=lPAYX8z9i8M&amp;t=495s to create a procedural cloud.

I got a single cloud right, however, when I scaled it up things started becoming glitchy.



Anyone have any ideas how to fix it?
Use a point light instead of a sun lamp. Sun lamps create shadows in one direction regardless of their placement, whereas a point light (or a spot or area light) emits only from a specific coordinate in the 3D environment.
