Radiant Canvas

Bring your own adapters

Use custom LoRAs in a Mac image generator

Radiant Canvas PRO can use up to ten custom LoRA or LoKr adapters in one generation. Presets are kept separate for each model family so they are easier to manage.

Keep styles ready to reuse

Add compatible adapters, adjust their strength, and save the combination as a preset. The next time you want the same setup, load the preset instead of adding every LoRA again.

Separate model families

A LoRA must match the model family it was made for. Radiant Canvas separates presets by family, which helps prevent an adapter from being applied to the wrong model.

Adapters stay private

Imported LoRA and LoKr files, their settings, and their presets remain on the Mac. They are not uploaded to Radiant Bear Games or a cloud generation service.

A LoRA is an extra file that changes how a compatible image model responds. It may add a visual style, a type of character, a product shape, or another learned subject. The file does not replace the main model. It works alongside it and usually has a strength setting that controls how much influence it has.

Compatibility matters. A LoRA made for one model family may not work with another, even if both can create similar images. Read the notes that came with the file and keep track of its expected trigger words. If a result looks broken or ignores the prompt, first check that the adapter belongs to the selected model family.

Begin with one adapter at a moderate strength. Add more only after you understand what the first one changes. Several strong adapters can compete with each other and make the result harder to control. A saved preset is useful once you find a combination that you expect to use again.
