Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| model_path | STRING | spacepxl/Wan2.1-VAE-upscale2x | HuggingFace model ID or local path. |
| subfolderopt | STRING | diffusers/Wan2.1_VAE_upscale2x_imageonly_real_v1 | Subfolder containing config.json + weights. Blank if model_path is already the dir. |
| dtypeopt | COMBO | bfloat16 | 3 options: bfloat16, float16, float32 |
| vae_tile_blendopt | COMBO | cosine | Tile-seam blending when tiling is active. cosine = C1-smooth (no grid lines). |
| downsample_to_1xopt | BOOLEAN | false | Decode at 2x (this VAE's native output) then Lanczos-downsample back to the generation's native 1x size, instead of returning the full 2x image. Trades the literal resolution gain for this decoder's sharper/GAN-trained detail at your original output size - a supersampling-style quality pass, not an upscale. Applies to the FINAL decode only (upscale_vae_mode='final_decode'/'both' on Ultra, or the standalone Upscale Decode node) - never to inter-stage upscaling, which exists specifically to gain resolution between stages. |
| blur_sigmaopt | FLOAT | 0.00–5 | Gaussian blur sigma applied at 2x, BEFORE the Lanczos downsample (standard supersampling order: blur to anti-alias, then resize). 0 = off - Lanczos' own resampling filter already does reasonable anti-aliasing on its own, so this is an extra taste knob, not a required step. Only used when downsample_to_1x is on. |
