Discontinuation of 3D features in Photoshop Photoshop’s 3D features will be removed in future updates. Users working with 3D are encouraged to explore Adobe’s new Substance 3D collection, which represents the next generation of 3D tools from Adobe. Additional details on the discontinuation of Photoshop’s 3D features can be found here: Photoshop 3D | Common questions on discontinued 3D features. Managing layers and groups keeps your project organized. You can rename layers, color-code to easily locate similar layers, and delete and export layers as needed. Rename a layer or layer groupAs you add layers or layer groups to an image, it’s helpful to give them names that reflect their content. Descriptive names make layers easy to identify in the Layers panel.
Assign a color to a layer or groupColor coding layers and groups helps you locate related layers in the Layers panel. Simply right-click the layer or group and select a color. Rasterize layersYou cannot use the painting tools or filters on layers that contain vector data (such as type layers, shape layers, vector masks, or Smart Objects) and generated data (such as fill layers). However, you can rasterize these layers to convert their contents into a flat, raster image.
Delete a layer or groupDeleting layers you no longer need reduces the size of your image file. To quickly delete empty layers, choose File > Scripts > Delete All Empty Layers.
Export layersYou can export all layers or visible layers to separate files.
Merging layersWhen you have finalized the content of layers, you can merge them to reduce the size of your image files. When you merge layers, the data on the top layers replaces any data it overlaps on the lower layers. The intersection of all transparent areas in the merged layers remains transparent. You cannot use an adjustment or fill layer as the target layer for a merge. In addition to merging layers, you can stamp them. Stamping allows you to merge the contents of more than one layer into a target layer while leaving the other layers intact. When you save a merged document, you cannot revert back to the unmerged state; the layers are permanently merged. Merge two layers or groups
You can merge two adjacent layers or groups by selecting the top item and then choosing Layer > Merge Layers. You can merge linked layers by choosing Layer > Select Linked Layers, and then merging the selected layers. You can merge two 3D layers by choosing Layer > Merge Layers; they will share the same scene and the top layer will inherit the bottom layer 3D properties (the camera views must be the same for this to be enabled). Merge layers in a clipping mask
For more information on clipping masks, see Mask layers with clipping masks. Merge all visible layers and groups in an image
Stamp multiple layers or linked layersWhen you stamp multiple selected layers or linked layers, Photoshop creates a new layer containing the merged content.
To stamp all visible layers, do the following:
Flatten all layersFlattening reduces file size by merging all visible layers into the background and discarding hidden layers. Any transparent areas that remain are filled with white. When you save a flattened image, you cannot revert back to the unflattened state; the layers are permanently merged. Converting an image between some color modes flattens the file. Save a copy of your file with all layers intact if you want to edit the original image after the conversion.
How do I merge layers in Photoshop with another layer?If you hold Alt (Mac: Option) while selecting “Merge Visible” in the Layer menu (or in the Layers panel flyout menu), you will merge the visible layers onto a new layer; leaving the original layers intact. You could also press Ctrl Alt Shift E (Mac: Command Option Shift E) to get the same result.
Why can't I merge layers in Photoshop?You can merge any kind of layers, but you need to have a pixel-based layer underneath them in the Layers panel to use the merge commands, or else they're grayed out (just add a new Image layer if you need to). Photoshop then merges everything onto that pixel-based layer.
How do you group layers on a Mac?To make a group, select some layers and choose “Group”, or use: macOS: Command-G. Windows: Control + G.
