UE4 includes a very rich material editor, fortunately it's very easy to use and we'll use it now to start making all the materials we're going to need.

For this tutorial I've chosen to use a concrete theme and for the ground, a mix between sand, grass and pavement.

Let's start with a very simple Chrome material.

  • Right click inside the Materials folder, we created this folder earlier in the tutorial but if you missed/skipped that, don't worry simply duplicate this file structure and continue.
  • Create a new Material, name the material M_Chrome, the M_ prefix denotes, in UE4speak, that this object is a material.

  • Double click to open the M_Chrome material to open it, right click in the Material Editor to add a Constant3Vector (Colour)
  • Set the colour to be white using the left side properties.

  • Add a Constant, value of 0 and connect it to the Roughness material pin.
  • Duplicate that constant (Ctrl-W), set it's value to 1 or .8 and connect the pin to the Metallic pin.

Material Instances

There are performance considerations for all elements of UE4 mapping, while the engine is very powerful a game with a rich enviroment and many player characters will require be required to draw things, calculate things and deal with network traffic on every tick of the engine and when we can reduce the load on what is required, the game will perform better.

Material Instances are more efficient method of creating materials (FIND REASONS)
