Checkpoint Loader v1 (Pipe)

This is the pipe loader to actually reach for from this pack's lineup: Checkpoint Loader v1 (Pipe) loads a checkpoint, applies the CLIP options you set, and hands you the whole thing as one pipe wire. The "v1" is a bit of a misnomer - it's the current, non-deprecated basic pipe loader, sitting alongside the trimmed Small variant and the fancier v2/v3 versions.

How it works

Standard ComfyUI loading (load_checkpoint_guess_config), then the RvTools packing step: model, clip, vae, latent (empty), width (8), height (8), batch_size (1), model_name and vae_name go into the pipe list. The CLIP handling is where it beats the Small loaders: Baked_Clip (default on) decides whether to use the checkpoint's own CLIP at all, and Use_Clip_Layer (default on) plus stop_at_clip_layer (default -2) control how deep into the CLIP stack you go. If Baked_Clip is off, the clip slot in the pipe comes out None - useful when you intend to load a CLIP separately.

The inputs that matter

• ckpt_name - the checkpoint file.
• vae_name - Baked VAE (default) or a separate VAE file.
• Baked_Clip - on: use the checkpoint's CLIP; off: pipe carries no clip (you add one later).
• Use_Clip_Layer + stop_at_clip_layer - SDXL-style CLIP truncation. -2 (the default) is the widely-used "one layer before the end" setting.

Output pipe feeds any RvTools pipe consumer - Pipe Switch, Pipe In Context, sampler-settings nodes.

Where it fits

The pipe it produces is the same 9-slot bundle the whole pack is built around, so this is the natural "start of graph" node for a workflow that then routes the pipe through switches or context nodes. If you want the same load but with resolution/batch baked in, that's v2 (Pipe); if you're loading split-model Flux/SD3 checkpoints, that's v3 (Pipe). This one is the plain, dependable middle.

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/r-vage/ComfyUI-RvTools_v2

Restart ComfyUI or use ComfyUI Manager (search "ComfyUI-RvTools_v2"). No model downloads - supply your own checkpoint.

Gotchas

The baked-in placeholder width/height of 8 in the pipe means you set real dimensions downstream (empty latent, or a resolution settings node) - don't be surprised when a metadata recorder reads 8x8. And the standing pack notes: the pack is unmaintained and deprecated in favor of ComfyUI_Eclipse; old v1-repo workflows reference node names that can no longer be installed. This particular node isn't itself deprecated, so it's one of the safer picks in the family.
