1. Add an Action node and edit the node settings

Start in Batch.
1. Drag an Action node to the Batch schematic.
2. Click the NodeSetup tab to the left of the interface to modify some of the Action settings.
Under the Rendering options, keep Z-Buffer ON.
Enable Shading.
Under the Miscellaneous options, change Auto Image to Auto Image OFF.
Turn AutoKey OFF to prevent animating values over time.

2. Load and connect the background

1. Swipe left to access the Batch Node Bin.
2. Drag the Library node to the Batch schematic to access the Library.
3. In the Library, select the clip “Phonograph_BG”.
4. Press Load.
5. Connect the image to the Action background tab.
6. Select the layer in the Action Media menu and click on Add Input.
7. Switch to Result view; press F4.

3. Import a FBX file in Action

We will import and modify a 3D model that was exported as a Film Box file from 3ds Max.
Note: First download and copy the FBX file to the system; don’t forget to upzip it as well.

1. Press ALT 2 to work with 2 view ports.
Set Action schematic on the left, press ~, and Result on the right, press F4.
2. Double-Click the Import node in the Action tool bin.
3. Choose FBX Click in the file type list.
4. Browse for the file “Comp2_Phonograph_FBX”.
5. Select the file and press Load.

4. Reposition the 3D models

The 3D elements are grouped under a main axis; each component of the phonograph is separated. The handle is animated. There are also three light objects that we will edit later. You can reorganize the nodes in the schematic and put the lights aside if you want.

1. In the Action schematic, double-click the top axis, “Phonograph_Group2”.
2. Position the objects to your liking or enter the following axis values:
Position X 160
Position Y -210
Position Z -500
Rotation X -80°
Rotation Y 0
Rotation Z 230
Prop Scale 500%

5. Change the textures of the wood box

We will change the texture of some of the 3D objects, adding the media directly inside the Action Layers.
1. Select in the Media tab and choose the options From Lib and Add Media.
2. Press Add Media.
3. In the Library, select the clip “Texture_dust_cc”.
4. Press Load.
Note: Since Auto Image is OFF in SetupNode, no image is added to the scene by default.
5. Select the geometry node “wood_box1” in the schematic.
6. Select the media layer that contains the texture.
7. Double-click the Texture icon in the Action image bin to add it to the scene.
8. Select the Geom node of the wood box.
9. In the Geometry tab, select Imported.
10.Deactivate the Use setting under Submaterials.
11.Double-click the texture object to look at the options.
12.Change the texture type to Wrap (UVs from geometry) and select Repeat (Smooth).
13.Also connect the Geom “base_Gold1” to the texture branch.
Now the two elements use the same texture.
14.Select the Geom node of “base_Gold1”.
15.Deactivate the Use setting under Submaterials.

6. Change the texture of the phonograph

1. Select in the Media tab and click Add Media.
2. In the Library, select the clip “Texture_reflect1”.
3. Press Load.
4. Select the geometry node “phonograph1” in the schematic.
5. Select media layer 2 that contains the texture.
6. Double-click the Texture icon in the Action image bin to add it to the scene.
7. Select the texture object in the schematic.
8. Keep the texture type to Reflection and select Mirror (Smooth).
9. Select the Geom node of the phonograph.
10.Deactivate the Use setting under Submaterials.
11.Connect the Geom “turnTable1” to the texture branch.
12.Select the Geom node of “turnTable1”.
13.Deactivate the Use setting under Submaterials.

7. Modify the lighting

There are imported lights in this scene but we need to adjust them to our current scene.

1. Select the Light “Omni02” in the Action schematic.
2. Under the Light Object tab, change the Intensity value to 60%.
3. Click in the light Colour pot and select a pale tone on the background.
This way the light shader will be of similar colors than the background.
4. Select the Light “Omni03” in the Action schematic.
5. Change the Intensity value to 80%.

8. Add a projector to the scene

We will use a projector to add a shimmering patina to the phonograph.

1. Select in the Media tab and click Add Media.
2. In the Library, select the clip “Texture_projector”.
3. Press Load.
4. Double-click the Projector icon in the Action image bin to add it to the scene.
5. Double-click the Projector in the schematic to access its menu.
6. Change the Projector mode to Spot Blend.
7. Reposition the Projector in the scene to your liking or enter the following projector values:
Position X 400
Position Y -230
Position Z 1000

9. Add a extended bicubic surface and exclude the projector to it

We will add a shadow to the phonograph and we need to prevent the projector to affect it.

1. Select layer in the Action Media menu and click on Add Media.
2. Swipe left to access the Batch nodes.
3. In the Library, hold CTRL and select the clips “Phonograph_shadow_fill” and “Phonograph_shadow_matte”.
4. Press Load.
5. Double-click the Extended Bicubic in the image tool bin.
6. We need to unlight the projector from the shadow image:
Change the Move operator to Lighting in the list, or press L.
7. Hold ALT for the exclude mode, and pull a link between the projector and the image branch.

10.Adjust the shadow surface

1. Double-click the ExtBicubic surface.
2. Position the shadow to your liking or enter these Axis values:
Centre X 70
Centre Y -300
Position X 100
Position y -250
Position XZ -600
Rotation X -80
Rotation Z -110
Prop Scale 80%
3. Set the Surface transparency to 50%.
4. Select the Vertices tab and press Subdivide.
5. Blur the image:
Go in the Media tab, and choose the layer with the shadow image.
6. Apply a Xblur of 80, and a YBlur of 60.
7. Adjust the surface points if needed:
8. Look at the Top and the Side views if you want, press SHIFT 4 and SHIFT 3.
