ComfyUI Node
(Deno) LTX Tiled Spatial Upscaler
DENO Custom Nodes vunknown. The DENO info button checks Comfy Registry and marks this node when an update is available. Runs the LTX latent spatial upscaler on overlapping spatial tiles, then reconstructs one video latent with float32 blending. Use it before a large low-denoise second pass when tall LTX outputs start drifting in colour or conditioning.

Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| samples | LATENT | Video-only LTX latent to upscale. AV combined latents should be separated before this node. | |
| upscale_model | LATENT_UPSCALE_MODEL | LTX latent spatial upscaler model. | |
| vae | VAE | LTX VAE used for the latent channel statistics around the upscaler. | |
| horizontal_tiles | INT | 21–8 | Frame width split count. 2 means left and right tiles. |
| vertical_tiles | INT | 21–8 | Frame height split count. 3 means top, middle, and bottom tiles. |
| overlap | INT | 81–32 | Overlap in input latent tokens. Larger values blend more context but use more time. |
| blend_modeopt | COMBO | hann | Overlap weighting curve. Hann is the recommended starting point. |
| aggressive_memory_cleanupopt | BOOLEAN | true | Run extra cleanup between tiles. This can be much slower, but may help fragmented VRAM or OOM cases. |
| debugopt | BOOLEAN | false | Print tile plan and shape diagnostics to the ComfyUI console. |
