| # MAGICK Transparency — raw WSG samples |
|
|
| Raw (pre-VAE) samples for the WSM v1 transparency-estimation pilot |
| (`magick_transparency_v1`): predict a foreground **alpha / transparency** layer from an RGB |
| image. The matching FLUX.2 latents live in the companion latent repo |
| `World-Snapshot/WSM_v1_Latent_PT_WSG_v1.8_for_Flux2` |
| (`custom_pilots/magick_transparency_v1/cache_named/`). |
|
|
| ## Source |
|
|
| Built from the **MAGICK** RGBA asset set (transparent foreground objects). Each foreground is |
| composited over random backgrounds so the model must recover the soft alpha of the object from a |
| realistic RGB image. |
|
|
| ## How each sample is produced |
|
|
| Each self-describing named-key `.npz` holds two modalities (`uint8`, `H×W×3`; the trainer maps |
| pixels with `x/127.5 − 1`): |
|
|
| | key | meaning | |
| |---|---| |
| | `0-2` | **RGB** — the foreground composited over a random background. | |
| | `LayerDiffuse_Transparency` | **target** — the RGB-replicated soft alpha / transparency of the foreground (1-channel alpha stored replicated to 3 channels). | |
|
|
| This is an estimation task: RGB → transparency. No caption, no reference image. |
|
|
| ## Layout |
|
|
| ```text |
| wsg_named/ the named-key .npz samples (0-2 + LayerDiffuse_Transparency) |
| ``` |
|
|
| `split_manifest.jsonl` records the deterministic train/val/test assignment used by WSM v1 training |
| (see `split_summary.json`); the split is per-sample (npz path), reproducing the trainer's hash split |
| at `val_split_ratio=0.05`. |
|
|
| ## Packaging |
|
|
| Streamed as multi-part `MAGICK_Transparency_partNNN.tar.zst` (each < 15 GB) with |
| `..._parts_manifest.jsonl` (path → part index) and `..._parts_summary.json`. |
|
|
| ### Extract |
|
|
| ```bash |
| mkdir -p data/custom_pilots/magick_transparency_v1 |
| for f in MAGICK_Transparency_part*.tar.zst; do |
| tar -xf "$f" -C data/custom_pilots/magick_transparency_v1/ |
| done |
| # -> data/custom_pilots/magick_transparency_v1/wsg_named/ |
