The 3D layer is added as a new 3D layer in the target document. It becomes the active layer in the Layers panel of
the target document.
4
In the Tools panel, select a 3D camera tool.
5
In the options bar, from the Position menu, select the layer name for the original 3D layer in the target file.
After you match the camera position of the two 3D layers, the two 3D objects appear together in the scene. Use the
3D object tools to reposition the objects before merging.
6
From the Layers panel options menu
, choose Merge Down.
The two 3D layers are combined into one 3D layer. The point of origin of each model is aligned.
Note: Depending on the size of each 3D model, one model may appear partially or completely embedded in the other
model after merging 3D layers.
After merging two 3D models, all meshes and materials from each 3D file are contained in the target file and appear
in the 3D panel. In the Meshes panel, you can select and reposition individual meshes using the 3D position tools in
the panel. See “
3D Mesh settings (Photoshop Extended)
To alternate between moving all models at once and moving individual models in the layer, switch between the 3D
position tools in the Tools panel and the tools in the Meshes panel.
Combine 3D and 2D layers (Photoshop Extended)
You can combine 3D layers with one or more 2D layers to create composite effects. For example, you can place a model
against a background image and change its position or viewing angle to match the background.
❖
Do one of the following:
•
With the 2D file open, choose 3D > New Layer from 3D File, and open a 3D file.
•
With both a 2D file and a 3D file open, drag either the 2D or 3D layer from one file into the open document
window of the other file. The layer you add moves to the top of the Layers panel.
When working in a file with combined 2D and 3D layers, you can temporarily hide the 2D layers while working
with the 3D layer. See “
Hide layers for better performance
Hide layers for better performance
In a multi-layer document with 2D layers above a 3D layers, you can temporarily move the 3D layer to the top of the
layer stack for faster screen rendering.
1
Choose 3D > Auto-Hide Layers For Performance.
2
Select a 3D Position or Camera tool.
When you hold down the mouse button with either tool, all 2D layers are temporarily hidden. When you release the
mouse, all 2D layers reappear. Moving any part of the 3D Axis also hides all 2D layers.
Create 3D animations (Photoshop Extended)
Using the Photoshop Animation timeline, you can create 3D animations that move a 3D model through space and
change the way it displays over time. You can animate any of the following properties of a 3D layer:
•
3D object or camera position. Use the 3D position or camera tools to move the model or 3D camera over time.
Photoshop can tween frames between position or camera movements to create smooth motion effects.
