Nodes

LoRA Nodes

RM Power LoRA Loader

A flexible node for loading multiple LoRAs with support for:

• Dynamic number of LoRA inputs (add as many as you need)
• Fixed or random strength per LoRA
• Style string import for automated LoRA loading

RM LoRA Collector

Combines multiple LoRA stacks into one. Accepts both LORA_STACK inputs and lora strings.

RM LoRA Apply

Applies all LoRAs from a collected stack to the model and CLIP.

Styles Nodes

RM Styles Full

Load prompts from a JSON styles file with multiple selection modes:

• Manual: Use specific prompt number
• Random: Random selection within range
• Increment: Auto-increment after each generation
• Decrement: Auto-decrement after each generation

Features an Edit Styles button that opens a modal editor for managing your styles.

RM Styles Full (Display)

Same as RM Styles Full but displays the current prompt on the node.

RM Styles Pipe / RM Styles Pipe Out

Pack and unpack style data for easier workflow connections.

Video Nodes

RM Video Combine

Combines images into video with:

• Multiple format support (H.264, H.265, VP9, GIF, WebP)
• Configurable output directory
• Metadata embedding
• Audio support
• Ping-pong looping

Utility Nodes

RM Image Fallback

Returns the first non-empty image from multiple inputs. Useful for conditional workflows.

RM Mask Gate

Validates masks and passes through only valid ones. Outputs None for invalid masks, preventing crashes in downstream nodes.

RM Mask Gate (Guide)

Same as Mask Gate but for guide inputs. Disables guides when masks are invalid.

RM Set Latent Noise Mask

Improved latent noise mask setter with proper error handling for edge cases.

RM Positive/Negative Text Embed

CLIP text encoding nodes that combine optional string inputs with text fields.

Styles JSON Format

The styles file (data/styles.json) uses this format:

{
  "styles": [
    {
      "number": 1,
      "name": "Style Name",
      "positive": "positive prompt text",
      "negative": "negative prompt text",
      "motion": "motion prompt for video",
      "imageLoras": [
        {"path": "lora_name.safetensors", "weight": 1.0}
      ],
      "motionLoras": [],
      "motionLorasHigh": [],
      "motionLorasLow": []
    }
  ]
}

Custom Video Formats

Add custom video formats by placing JSON files in the video_formats directory. Example format:

{
  "extension": "mp4",
  "main_pass": ["-c:v", "libx264", "-preset", "medium", "-crf", "19", "-pix_fmt", "yuv420p"],
  "audio_pass": ["-c:a", "aac", "-b:a", "192k"],
  "save_metadata": "True",
  "dim_alignment": 2
}
