Hero Image Transfer allows you to modify existing images using a text prompt as a control. This is useful for exploring possible variations of an scene, assert or character, or rendering low-fidelity color-blocked images into stylized and shaded ones.
Your Alpaca plugin may look a bit different than in the video as we are constantly improving it.
Transfer is controlled by two inputs:
  • a reference image
  • a text prompt.
The base reference image will specify the general form and the underlying color palette, though depending on the Transfer Strength parameter, Alpaca will be more or less liberal in altering the form. The text prompt can be used to alter the art style, silhouette, and shading/lighting of the reference image. Typically, Transfer stays close to the original color palette. You can find some example reference images and prompts like the ones used in this example below.
Prompt
treasure chest, cyberpunk, sci-fi, futuristic, technology, post-apocalyptic, masterpiece, best quality, epic, cinematic lighting

​
Reference Image

You can also guide Imagine by leveraging existing images as a template, also known as a “reference” image. We currently support 4 types of references:
  • Pose: Extracts the specific pose of a character from the reference image to generate new images of characters in identical poses.
  • Depth: Preserves the spatial arrangement or ‘composition’ of the reference image in the newly generated images.
  • Hard Edges: Matches the sharp boundaries, lines or ‘edges’ found in the reference image in the generated images.
  • Soft Edges: Similar to Hard Edges but with a bit more freedom allowed.
Check our guide Using References to Guide Composition to learn how to use references with Alpaca.

Parameters

​
Prompt

The Prompt box, located in the main section of the Alpaca panel, takes in a text prompt describing the subject matter, style, composition, and characteristics of your desired image. You can also describe what you do not want to see in the output by clickling on Exclude. You can learn more about writing prompts by checking our our Prompt Guide.

​
Images

Allows you to specify how many images you want Alpaca to generate from 1 to 5. The higher the number of images, the more credits the generation will cost, and the slowest it will be.

​
Seed

The seed acts as a unique identifier, guiding the creation process of each generation. If you retain the same seed with identical settings, the output will always be the same. Retain the seed, while changing other parameters (e.g. altering the prompt) and you’ll derive a distinct yet related creation. For an element of unpredictability, set the seed to 0 and Alpaca will choose a random seed for each image, creating more variations

​
Steps

Higher number of steps will lead to better quality, but also cost more credits and make the generation slower.

​
Prompt Strength

The Prompt Strength slider controls the influence of the prompt — higher values of this parameter force the model to be more attentive to the prompt. We can consider this to be a “rigid” vs “relaxed” interpretation of the prompt. 7 is a good balance.

​
Transfer Strength

The Transfer Strength slider is found in the Advanced settings tab. It controls the degree to which changes are made to the input image. A low Transfer Strength will keep the output close to the original input image, while a high value will add more shading, lighting, detail, and compositional variation to the output.
