Node Limitations

You can use all unreal nodes in the graph, just as when creating material keeping just a few limitations in mind.

• All the "vertex" data nodes like World Position, and World Normal. Red-colored nodes. They're probably not what you want when used in Material Mask Materials. They work but they have data from the post process material rendering plane and not "real" world position/normal. You must use World Position, World Normal etc from the Biomes category.

• TexCoord node is fine and so is using Texture Sample with default arguments but keep in mind that each Generation Component generates separately. UVs that you get during generation are UVs of the plane of that component.
