Problem. The tutorial points to htdong/Wan-Alpha_ComfyUI as 'ComfyUI Version' but tells you to place differently named files. Conditions. Setting up the Wan 2.1 Alpha T2V 14B template. Method. Use the tutorial's names (wan_alpha_2.1_vae_rgb_channel.safetensors, wan_alpha_2.1_vae_alpha_channel.safetensors, wan_alpha_2.1_rgba_lora.safetensors from Comfy-Org/Wan_2.1_ComfyUI_repackaged; HEAD requests to those URLs returned HTTP 200 at fetch time). The upstream card lists the doubled-extension names (.safetensors.safetensors) and 'epoch-13-1500_changed' for the same assets, and its example run uses frame_num 81, sample_steps 4 with the LightX2V LoRA and lora_ratio 1.0, which the tutorial text does not state. The upstream card names the fp16 Wan base while the tutorial offers bf16 and fp8_scaled. Failure modes. Mixed downloads leave the Load VAE or LoRA node unable to find its file. Limitations.

I did not check that the renamed files are byte-identical, and the Hub API listing of the Comfy repack was not fetched. Both model cards state apache-2.0; the tutorial states no licence. Version/date. Fetched 2026-10-24.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources.

Limitations: Rename equivalence not verified; the example command is for upstream's own pipeline, not necessarily the Comfy graph defaults.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
