<h1>Workflow nodes<a class="headerlink" href="#workflow-nodes" title="Permalink to this headline">ΒΆ</a></h1>
<p>The workflow nodes can be used to organize the generation of complex materials, based
on simple homogeneous materials and maps that describe the overall geometry of the
whole material.</p>
<p>The <strong>CreateMap</strong> node is used to create a map that holds the height, orientation and
offset of the material.</p>
<img alt="_images/workflow_map.png" class="align-center" src="_images/workflow_map.png" />
<p>The <strong>MixMaps</strong> node can be used to combine maps (based on their
height information) that will be applied to the same material.</p>
<img alt="_images/workflow_mixed_maps.png" class="align-center" src="_images/workflow_mixed_maps.png" />
<p>Base (flat) materials consist of albedo, ORM (ambient occlusion, roughness, metallic),
emission and normal channels. A few example materials are provided in the
<strong>Workflow/Materials</strong> section of the library.</p>
<img alt="_images/workflow_base_material.png" class="align-center" src="_images/workflow_base_material.png" />
<p>Maps are then applied to base materials using the <strong>ApplyMap</strong> node to generate
new (reoriented and offset) materials (with albedo, ORM, emission and normal) associated
to height information.</p>
<img alt="_images/workflow_applied_map.png" class="align-center" src="_images/workflow_applied_map.png" />
<p>Different materials with height information can then be mixed based on their height
using the <strong>Mix</strong> node to generate more complex materials.</p>
<img alt="_images/workflow_mix.png" class="align-center" src="_images/workflow_mix.png" />
<p>The result can then be fed into the <strong>Material</strong> node using the <strong>Output</strong> node, that
generates the overall normal and ambient occlusion maps using the height map.</p>
