2 Feature Workflow

State the goal of the workflow here. What will be covered in the workflow | What does it test | How will it look in the end (You can post a screenshot of a completed workflow here as a guide)

2.1 Preparation & Prefabs

List any necessary steps that must be done beforehand.

Include any prefabs that can be used to make putting together the workflow easier.

2.2 Workflow Steps

Create a step-by-step guide for the workflow. The steps themselves should be simple, and the workflow should be comprehensive.

Physical Sky

• Create a new level
• Select the Shaderball entity
• Set the material component to "basic_m10_r-2" 
• Add three new entities to the level, add a mesh asset to each (such as: "lucy_high.fbx", "bunny.fbx", and "suzanne.fbx")
• Add a different material to each, try to vary the reflective and roughness of the materials 
• Place one object close to the shadershphere and on the same plane (about 1.5-2.5 meters), one at medium (about 3-4 meters), one further away (about 8-9 meters)
• Delete the Global Sky element
• Add a new entity to the level, give it a Physical Sky component
• Level should look similar to this:

• Change the Sky Intensity slider and observe change in level

Sky Intensity 0.65

 Sky Intensity 4.5

• Change Sky back to Intensity to 4.0
• Change the Sun Intensity slider and observe change in level

Sun Intensity 3.5

Sun Intensity -4

• Change Sun Intensity back to 8
• Adjust Turbidity value from 1-10, observe color change in sky
• Set Turbidity back to 1
• Adjust Sun Radius Factor from 0.1 - 2.0, observe change in sun
• Change Sun Radius Factor back to 1.0
• Enable Fog
• Change Fog color, increase top height, and bottom height
  Example of fog:

Steps to create a modular Physical Sky. (Had help from Jonny after asking why no light cam from the Physical Sky)

• Create Entity

• Zero out transforms

• Add Physical Sky Component

• Add Deferred Fog Component

• Add PostFX Layer

• Add the Sun under this Entity (Make the new Physical Sky Entity the parent)

• Zero out the Sun Transforms

Now you will have a modular Physical Sky, see image:

Placing multiple Diffuse GI Probes and Reflection Probes in a level 

• Create a new level
• Select the Shaderball entity
• Set the material component to "basic_m10_r-2"
• Copy 
• Add six or more new entities to the level, add a mesh asset to each (such as: "lucy_high.fbx", "bunny.fbx", and "suzanne.fbx")
• Add a different material to each, try to vary the reflective and roughness of the materials
• Move each around the origin on the XY plane, for 1-10 meters 

Deferred Fog

• Create a new level
• Select the Shaderball entity
• Set the material component to "basic_m10_r-2"
• Add three to six new entities to the level, add a mesh asset to each (such as: "lucy_high.fbx", "bunny.fbx", and "suzanne.fbx")
• Add a different material to each, try to vary the reflective and roughness of the materials
• Move each around the origin on the XY plane, for 1-10 meters 
• Add a new Entity to the level named "Fog"
• Add a "Deferred Fog" component to the entity and the required PostFX Layer
• Change the Fog color, and adjust the Fog Start Distance to around 5 and Fog End Distance to around 15
  Example:

• Turn on "Enable Fog Layer" and "Enable Turbulence Layer"
• Change noise texture
•  Adjust each of the noise settings, observe the result

Example:

• Adjust the "Octave Blend Factor" observe the result

Example:

Multi-Layer Materials

In Blender, Maya or Max add Multi UVs Maps (Sets) to your mesh object.

Export an .FBX

In o3de:

Drag the FBX into the scene.

Under the Entity, Add the Material Component.

Launch the o3de material O3DE Material Editor

Under File > New

Select the Standard MultilayerPBR Material.

After playing around with this Material Type, I think it has opportunities to be more intuitive, also has some broken areas I will report as bugs.

Decals

• Use AutomatedTesting as the active project.
• Launch Editor, create a new level
• Add an entity, and assign a mesh component to it
• Assign the cone.fbx to the mesh component, and give it a non-reflective material
• Create two more entities, and add decal components to each
• Assign the first decal to the material "airship_symbol_decal"
• Assign the first decal to the material "airship_nose_number_decal"
• Move the first decal near the cone, and rotate until it project on the cone

Example:

• Adjust Attenuation Angle observe change in icon (should become more opaque at lower values)
• Adjust Opacity observe change in icon (should become more opaque/transparent up to the limit of Attenuation Angle)
• Move the other decal so it projects on the cone, on top of the first decal
• Set both decal's Attenuation Angle to 0.0
• Adjust the Sort key of each decal, confirm that the decal with the lower key is obscured by the decal with the higher key

Example:
