DLN RTX Tile Refiner
Splits an image into a grid of smaller tiles, applies KSampler with a lower denoise to each, and merges them back. Best for upscaling or adding high-res details.

| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | — | |
| model | MODEL | — | |
| positive | CONDITIONING | — | |
| negative | CONDITIONING | — | |
| vae | VAE | — | |
| seed | INT | 00–18446744073709550000 | — |
| steps | INT | 201–10000 | — |
| cfg | FLOAT | 8.00–100 | — |
| sampler_name | COMBO | 44 options: euler, euler_cfg_pp, euler_ancestral, euler_ancestral_cfg_pp, heun, heunpp2, +38 | |
| scheduler | COMBO | 9 options: simple, sgm_uniform, karras, exponential, ddim_uniform, beta, +3 | |
| denoise | FLOAT | 0.250–1 | — |
| grid_divisions | COMBO | 5 options: 2x2, 4x4, 8x8, 16x16, 32x32 | |
| overlap | INT | 320–512 | Overlap between tiles in pixels to prevent visible seams. A smart minimum is enforced automatically. |
| mode | COMBO | Refiner (Same Size) | Refiner keeps the original resolution but adds details. Upscale increases the final image resolution based on the RTX factor. |
| rtx_upscale_factor | FLOAT | 1.001–4 | Upscale factor using Nvidia RTX before refining. 1.0 disables it (requires nvvfx). |
| rtx_quality | COMBO | HIGH | 4 options: LOW, MEDIUM, HIGH, ULTRA |
| blend_mode | COMBO | Smoothstep | Blending algorithm for tile transitions. Smoothstep and Gaussian are much smoother than Linear. |
| sharpening | FLOAT | 0.000–1 | Unsharp mask strength applied to the final result. 0=disabled. 0.3-0.5 recommended for crisp details. |
| color_match_strength | FLOAT | 0.000–1 | Match refined tile colors to the original to prevent color drift between tiles. 0.7-0.9 recommended. |
| detail_inject | FLOAT | 0.000–0.5 | Inject noise into the latent before sampling to encourage micro-detail generation without increasing denoise. 0.05-0.15 recommended. |
| context_padding | INT | 00–128 | Extra pixels extracted around each tile for KSampler context. Discarded after processing. 32-64 recommended for better tile coherence. |
| maskopt | MASK | Optional mask to only refine specific areas. Tiles not covered by the mask will be skipped. |
