Because all of the Infinite Builders were built using the nodes that come shipped with Blender, they should work in any version of Blender that has these nodes, though I would always recommend anything above 2.8 to be certain as this is the version they were built on. All of the Infinite Builders are fairly GPU intensive, on an RTX 2060 with dedicated 8gb ram it's very smooth in the viewport, but on a mac with an ATI HD5770, the updates are somewhat slower, though still workable.

It was built on an i7 8th Gen 8750H, an NVIDIA RTX 2060 with 16Gb ram.

You'll receive individual manuals for The Infinite Metal and Brick Wall Builders and the tutorials are available as links on each page. The manuals are in the downloads section.
