Triplanar Projection Material Creator enables you to easily create custom triplanar projection materials from any PBR texture set.

It comes with a variety of premade materials that are perfect for quick prototyping in Unreal Engine.

What is triplanar projection/mapping: 

Instead of utilizing the UVs of an object to apply the textures, with triplanar projection, the texture gets projected from the world space X, Y & Z axes onto the object. This allows you to materialize any object, without the need for a UV layout.

Features:

•  create your own Triplanar Projection Materials from any PBR texture set

•  52 premade Materials, including bricks, stone walls, rock, metal, concrete, wood, tiles & wallpapers
