The metallic map tells the renderer which parts of the model are metallic. In this example the bow and arrow and the rucksack straps.

ORM map

To save precious video memory, the occlusion, roughness and metallic maps are stored in the same texture. This is the ORM map:


The AdvancedMaterials\ColourmapNormalmapCubemap effect uses the metallic map to set the visibility of the cube map. This effect is automatically selected when your model features an ORM map.

When you choose MEDIA > CHANGE EFFECT... you can see how this effect uses its textures:
1st texture slot: colour map
2nd texture slot: normal map
3rd texture slot: cube map
4th texture slot: ORM map

All textures are automatically loaded from the 3D model, except the cube map:

Cube map

The BluffTitler installer comes with an example:

Here's more about cube maps:

Render 1

The 1st render does not use a cube map. This way nothing looks metallic.

Render 2

The 2nd render uses in its 3rd texture slot. But the FX IGNORE METALLIC MAP is set to 1. This ignores the metallic map so everything looks metallic.

I've cleared the normal map to make it super smooth.

Render 3

The 3rd render keeps the FX IGNORE METALLIC MAP prop to its default value of 0. This makes only the metallic parts look metallic. Clearly this looks best!

The FX REFLECTION FACTOR prop is set to 2 to boost the effect.

Other props

The FX NORMAL STRENGTH prop is set to 2 to boost the normal maps.
The SPECULARITY prop is set to 0.9 to add specular reflections.

Very COOL! Thank you Michiel!

Here's another demonstration of the power of metallic maps.

Thank you for the clarification.

Realize that the same can be achieved by splitting your model into its submodels: a separate layer for every submodel. This way you can set the FX REFLECTION FACTOR prop differently for every submodel. A metallic map automates this: it achieves the same with only a single layer!

Here's another spectacular example.

I've set the FX REFLECTION FACTOR in the 3rd render to 1.3. This way the metallic parts take over the mustard green a bit.
