Nodes that are considered to be "Clump Fall Nodes" are everything that falls outside of the Falling Nodes, Attached Nodes, Liquid, and Unbreakable groups. Anything that doesn't belong to those groups, including nodes that are registered by other mods, will fall into this category.
This is far from my first ever program, but it is my first time writing anything in Lua. Wish me luck.
As for screenshots, what is shown here is essentially a "comic" consisting of 6 screenshots, detailing the process of the collapse of the roof of a cave, which was initially formed by a lot of explosions. Though the light is low, through sillhouettes formed by nodes in the bright fog, you can see somewhat of step-by-step process of how these stone blocks are falling, the first and last images especially being usable as before/after photos.
