Hi all, This bug that Matt squashed should fix some problems with the volume rendering for non-Enzo codes such as FLASH, Orion, and Castro. It had to do with the AMR kd-tree build process and grid id offsets. Anyways, if you had been having trouble with volume rendering, you may have better luck now. Good catch Matt!
