Velox can work with custom post types when two conditions are met.

Thumbnail support

The custom post type must support WordPress post thumbnails/Featured Images. If WordPress does not expose a Featured Image for the content type, Velox has no native image source to resolve.

Elementor rendering

The relevant content or template must be rendered through Elementor in a supported context.

Theme-owned output

If a theme renders a CPT header or title bar completely outside Elementor, Velox does not take over that theme-controlled area.
