📝 Walkthrough

Walkthrough

comfy_api_nodes/nodes_wan.py adds two image-validation utilities to its import list and extends three Wan video-generation nodes with HappyHorse 1.1 model variants. HappyHorseTextToVideoApi, HappyHorseImageToVideoApi, and HappyHorseReferenceVideoApi each gain a new happyhorse-1.1-* model branch in define_schema, with the Reference node also receiving expanded ratio choices and an autogrow input. The price_badge calculation in all three nodes is updated to apply a different per-resolution PPS table when the selected model contains "1.1". In the execute methods of the Image-to-Video and Reference Video nodes, input images are now validated for minimum dimensions and allowable aspect ratio before any upload or media construction occurs. The error message for missing reference images is also updated.
