Materials

Materials are built with Cycles nodes.

Displacement

Locate the Armory Render Path - Renderer - Displacement property:

• Off - No displacement performed
• Vertex - Mesh vertices are displaced
• Tessellation - Mesh is first tessellated for more detail and then displaced

With Tessellation selected, the level of tessellation can be set using the Mesh and Shadow property.

Note: Vertices are displaced in normals direction. Use smooth shading (Space - Shade Smooth) for meshes with displacement to prevent gabs.

When using a height texture map, you can place an Armory PBR node and connect the height map to the Height socket. Make sure to also connect the Displacement sockects.

Blending

To enable additive blending for specific material, set Armory Render Path - Blending to On and check the Blending property in Material - Armory Props.

Material parameters

RGB, Value and Image Texture material nodes can be controlled at run-time using script or logic nodes. To expose material node, enable Parameter property in Node Editor - Properties - Armory Material Node.
