At last, something exciting! This is a tool that admittedly, might not have a huge amount of use, but does have some fun features to play with. I’ve developed a set of nodes for generating, filling, lighting and rendering voxel grids in Nuke. You may also notice a new link above to a documentation page for the new nodes, as it includes quite a lot and could be confusing to use without a bit of an explanation.
The tool is available for download here on nukepedia.
