Editing images with Seedream 5.0 Layers

Seedream 5.0 Layers is a third-party image generation model from Bytedance, available on Runway. It splits a single image into separate, editable layers with state-of-the-art separation — for example, you can take a product photo and isolate the subject, background, and other elements into individual layers you can toggle, reposition, or transform independently.

This article covers how to access Seedream 5.0 Layers in Tool mode, prompt best practices, using the Runway layer editor, and more.

Step 1 – Selecting Seedream 5.0 Layers

Seedream 5.0 Layers is available in Tool mode. To access it:

  1. From the left navigation bar, click Tool.
  2. Select the Image tab at the top of the generation panel.
  3. Click the model dropdown at the bottom of the panel and search Seedream 5.0 Layers.

 

Step 2 – Writing the prompt (optional)

Upload the image you want to split into layers. Once uploaded, you can generate right away without a prompt, or add one for more control.

The model automatically identifies and separates the contents of an image into distinct transparent layers, so prompts are optional. Add one when you need finer control over how layers are split, or when you're isolating smaller elements within the image.

When you do add a prompt, describe the specific elements you want separated so the model knows what to isolate onto its own layer.


 

Step 3 – Editing or downloading layers

Once the generation processes, the layer editor will appear in your session:

The editor lets you to make adjustments to each layer without leaving Runway. If you'd rather work in external editing software, see the Export layers dropdown in the Downloading Edits or Exporting Layers section.

Only the separation process (clicking Generate) uses credits, so you can download your edits as many times as you like at no extra cost.

 

Layer management

Select a layer

Click an element directly in the image editor, or choose it from the layer list on the right side of the screen.

Hide a layer

Click the eye icon next to a layer to hide it from view.

Reorder a layer

Use the up and down arrows to move a layer forward or backward in the stack. Layers at the top of the list sit in front of everything below them.

 

Editing layers

Move a layer

Select the layer, then click and drag it anywhere in the editor.

Resize a layer

Select the layer, then click and drag one of its resize handles to scale it up or down.

Downloading edits or exporting layers

If you'd rather continue editing in photo editing software, bulk download the layers from your Recents folder instead:

  1. Click Recents in the left-hand navigation bar
  2. Click the first asset in the group
  3. Hold SHIFT and click the last asset to select everything in between
  4. Click Actions, then click Download.
