📝 Walkthrough

Walkthrough

comfy_api_nodes/nodes_wan.py is updated to support HappyHorse 1.1 model versions across all three node variants. The define_schema() method in each node (HappyHorseTextToVideoApi, HappyHorseImageToVideoApi, HappyHorseReferenceVideoApi) now exposes happyhorse-1.1-t2v, happyhorse-1.1-i2v, and happyhorse-1.1-r2v options respectively, with updated ratio and template sizing. Each node's price_badge expression is changed to select different per-resolution PPS rate tables depending on whether the chosen model string contains "1.1". Two new image validation helpers (validate_image_aspect_ratio, validate_image_dimensions) are imported and applied in execute() for the I2V and R2V nodes, enforcing minimum dimensions and aspect-ratio constraints on input images. The empty-media error message in HappyHorseReferenceVideoApi is also updated.
