The goal of this pack is to keep genuinely useful glue nodes in one place without pulling in a large third-party custom-node bundle just to get one tiny piece of functionality.

Included

`Text Split (Delimiter)`

Splits an input string using a delimiter and returns:

part_1 through part_20
remainder
count

Behavior:

output_count controls how many leading parts are emitted before overflow is collected into remainder
strip_parts trims whitespace around each part
skip_empty removes empty parts after splitting
delimiter supports common escape strings such as \n, \r\n, \r, and \t

This node intentionally uses a fixed socket layout instead of dynamic outputs so saved workflows stay predictable and easy to debug.

`Lazy Index Switch`

Selects one of input_0 through input_19 using a zero-based index value.

Behavior:

accepts any ComfyUI type on its input sockets
evaluates only the selected input branch
pairs with combo-style nodes that expose an INDEX output
reports a clear validation error if the selected input is not connected

`Enviral Image Resize Kit`

Resizes an image with a small set of explicit workflow-friendly modes:

pass-through: keeps the input image resolution and ignores width/height
explicit resize: stretches the image to the requested width and height
inside fit: preserves the full image, pads to the requested aspect ratio, then outputs the requested width and height
outside fit: fills the requested aspect ratio and center-crops overflow

The mode input is a dropdown, but it also accepts linked strings such as resize, pad, crop, and pass-through. This makes it pair cleanly with combo nodes that output strings. Optional masks are transformed with the same geometry and the node returns image, width, height, and mask.

`Enviral Color Match V2`

Transfers color from a reference image batch to a target image batch.

Inputs:

image_target: image batch to recolor
image_ref: image batch to sample color from
method: mkl, hm, reinhard, mvgd, hm-mvgd-hm, hm-mkl-hm, or reinhard_lab_gpu
strength: blend/extrapolation amount, where 0 is unchanged and 1 is the matched result
multithread: enables threaded CPU processing for multi-image batches

The CPU methods use color-matcher. The reinhard_lab_gpu method uses ComfyUI's Kornia dependency for Lab-space matching.

`Model Patch Torch Settings`

Patches a MODEL with ComfyUI model callbacks for PyTorch backend settings.

Inputs:

model: model to clone and patch
enable_fp16_accumulation: toggles torch.backends.cuda.matmul.allow_fp16_accumulation while the model runs

When enabled, the patched model turns full FP16 accumulation on before model execution and turns it back off during cleanup. When disabled, it forces the setting off before model execution.

`LM Studio Unified (URL + API Key)`

Sends text, an image, or both to an LM Studio OpenAI-compatible chat endpoint.

Inputs:

base_url: accepts http://127.0.0.1:1234/v1, https://lmstudio.example.com, or a full /v1/chat/completions URL
api_key: optional bearer token for LM Studio API-token auth
api_key_env_var: optional environment variable fallback when api_key is blank, defaulting to LMSTUDIO_API_KEY. On Windows, this checks the current process first, then the User and Machine environment variable registry values.
model, prompt, system_prompt, seed, max_tokens, temperature, and timeout_seconds
optional image input for vision-capable models. If the input is an IMAGE batch, each frame is sent as a separate image_url content part, capped by max_images

For a secured Cloudflare route, use a public base_url such as:

https://lmstudio.enviral-design.com

The node will call:

https://lmstudio.enviral-design.com/v1/chat/completions
