I imported a VDB volume from Houdini into Blender 2.92 and it creates some weird shadows. How could I make it not cast any shadows? I went into Visibility > Ray Tracing but there's no Shadow tickbox.

  • $\begingroup$ Can you show me a picture of the correct version? The glitch could be a number of things in the current picture. $\endgroup$

  • $\begingroup$ The version without the glitch. More clearly, the version where the volume is hidden. Possibly also add circling on the problem version to show exactly where and what the problem is. $\endgroup$
