Portal Frame is a block that makes up the roots and outside trunk of the Portal Tree. On most of the tree, it appears with just the bark texture, but surrounding each portal it creates a frame design made up of many different textures. It is purely decorative.
- Beta 2.0.0: Now generates on all outside parts of the portal tree, taking on a plain bark texture on most parts of the trunk, replacing Portal Tree Bark.
- Beta 1.0.0: Introduced.
