https://iconicwp.com/products/woocommerce-product-configurator/

With WooCommerce Product Configurator you can create image “layers” using transparent PNGs for each attribute of a variable product. This means instead of a single image for each final variation, you can create far less “layered” images, and have them configure themselves visually on the frontend as the customer selects their product options.

Changelog

[new] Compatibility with the single product block.

[new] Added several developer filters to support offloading generated images to a CDN.

[new] Added new logic and the `iconic_pc_disallowed_params` developer filter to strip unwanted parameters causing generated thumbnail images to break.

[update] Refactored caching implementation and introduced automatic cleanup of cached image files when the transients expire.

[update] Slight refactor to front-end javascript to improve compatibility with plugins that hide the variations table and provide their own variations UI e.g Extra Product Options & Add-Ons.

[update] Telemetry now shares a dependency injection container with other Iconic products for performance.
