How to Fix Figma Weave Ignoring Custom Variables

When using Figma Weave to generate layouts, UI code, or design systems, the model relies on your file's underlying variables to generate accurate, tokenized structures. If Figma Weave suddenly begins ignoring your custom variables—reverting to hardcoded hex values, raw CSS, or generic fallback styles—the issue is typically caused by model context window saturation, token schema mismatches, or unsynced file libraries.

This guide explains how to troubleshoot and resolve issues where Figma Weave fails to recognize and apply your custom variables.

1. Verify Variable Publishing and Library Sync Figma Weave runs its generation processes in the cloud, utilizing the cached state of your design library. If you have created or edited custom variables locally but have not published them, the Weave model will fall back to default values or generate hallucinated styles.

1. Open your Figma library file where the custom variables are defined.
2. Click the Publish button (the book icon in the upper-right toolbar) to open the Library modal.
3. Verify if there are any outstanding variable changes that need to be published.
4. Click Publish changes.
5. Go back to the working file where you are executing Figma Weave. Look for the update notification in the bottom right corner and click Update to pull the latest variables into the working file's active memory.

2. Check for Token Naming Conflicts and Schema Errors Figma Weave uses semantic analysis to map generated UI components to your design tokens. If your custom variables use non-standard naming conventions, duplicate names across different modes, or invalid structures, the model's parser may ignore them.

1. Open your Local Variables panel.
2. Ensure your naming architecture follows a strict semantic hierarchy (e.g., color/brand/primary instead of color-primary-new-final).
3. Check for naming collisions across different groups or collections. If you have button-padding as both a float variable and a string variable, Weave may reject the variable token completely.
4. Ensure that the values assigned to your variables match their declared types. For example, a color variable must contain a valid hex, RGB, or HSL value, and a number variable must contain a valid integer or float without trailing text units (like px or em).

3. Clear Local Figma Cache and Force Synced State Sometimes, the local Figma client experiences a state mismatch, causing Weave to send outdated or incomplete file schemas to the generation engine. Clearing your local cache forces Figma to rebuild the component and variable map.

On Desktop (macOS): 1. Close Figma completely. 2. Open **Terminal** and run the following command: `rm -rf ~/Library/Application\ Support/Figma` 3. Relaunch Figma, open your file, and run Weave again.

On Desktop (Windows): 1. Close Figma completely. 2. Open the **Run** dialog (`Windows Key + R`), type `%APPDATA%\Figma`, and press Enter. 3. Delete all folders and files inside this directory. 4. Relaunch Figma and verify if Weave reads the custom variables.

4. Reduce Context Window Saturation If your file is exceptionally complex—containing hundreds of layers, complex nested components, and multiple variable collections—the Weave engine can exceed its context token limit. When this happens, the model prioritizes structural layout generation and drops complex variable mappings to stay within performance limits.

1. Copy the specific components or layers you want to work on into a clean, blank Figma file.
2. Link your published library containing the custom variables to this new file.
3. Run Figma Weave within this isolated environment.
4. Once the model successfully generates the output using your custom variables, copy the results back into your main production file.

5. Explicitly Instruct Weave in Your Prompt If Weave continues to generate hardcoded values, you may need to explicitly guide the underlying model to prioritize your active variable library over its default generation patterns.

1. Open the Weave prompt input window. 2. Prepend your prompt with a direct instruction pointing to your variables. For example: "Using only the active 'Brand Variables' collection in this file, generate a primary card component. Do not use hardcoded hex values or raw CSS sizing; map all colors and spacing to our local variable tokens." 3. Avoid using ambiguous language like "use my styles." Use specific terms like "local variables" or "published design tokens."

When to Escalate If Figma Weave consistently ignores your variables even in a clean, isolated file with simple, published tokens, there may be an active bug in the model's parsing engine or a service disruption on Figma's servers. Check the Figma Status page to see if there are active incidents affecting AI features or design systems. If all services are operational, file a bug report directly through Figma Support with a link to a test file demonstrating the broken variable mapping.
