Understanding the String to Curves Node

Oct 13, 2025 by wbrum.org 101 views

Introduction

When working with Geometry Nodes in Blender, one of the most powerful features is the ability to generate complex geometry from simple inputs. One such input is the String to Curves node, which allows you to convert text into a 3D curve. However, by default, this node treats the entire string as a single curve, making it difficult to manipulate individual characters. In this article, we will explore how to separate individual characters from a string to curves in Geometry Nodes, allowing you to manipulate each character independently.

Understanding the String to Curves Node

Before we dive into the solution, it's essential to understand how the String to Curves node works. This node takes a string input and converts it into a 3D curve. The curve is generated by creating a series of connected points, where each point represents a character in the string. The node uses a font to determine the shape and size of each character, and the spacing between characters.

The Problem with Individual Characters

When you use the String to Curves node, each character in the string is treated as a single segment of the curve. This means that if you want to manipulate individual characters, you're limited to modifying the entire curve. For example, if you want to rotate a single character, you'll have to rotate the entire curve, which can be frustrating and time-consuming.

Separating Individual Characters

To separate individual characters from a string to curves, you'll need to use a combination of Geometry Nodes and a few clever tricks. Here's a step-by-step guide to achieve this:

Step 1: Create a String to Curves Node

First, create a new Geometry Nodes group and add a String to Curves node. This node will take the string input and convert it into a 3D curve.

Step 2: Use a Split Node

Next, add a Split node to the Geometry Nodes group. This node will split the curve into individual segments, where each segment represents a character in the string.

Step 3: Use a Separate Node

Add a Separate node to the Geometry Nodes group. This node will separate the individual segments into independent geometry.

Step 4: Use a Geometry Node Group

Finally, add a Geometry Node Group to the Geometry Nodes group. This group will allow you to manipulate individual characters independently.

Configuring the Geometry Node Group

To configure the Geometry Node Group, follow these steps:

Step 1: Add a String to Curves Node

Add a String to Curves node to the Geometry Node Group. This node will take the string input and convert it into a 3D curve.

Step 2: Add a Split Node

Add a Split node to the Geometry Node Group. This node will split the curve into individual segments, where each segment represents a character in the string.

Step 3: Add a Separate Node

Add a Separate node to the Geometry Node Group. This node will separate the individual segments into independent geometry.

Step 4: Add a Geometry Node Group

Finally, add a Geometry Node Group to the Geometry Node Group. This group will allow you to manipulate individual characters independently.

Manipulating Individual Characters

Now that you've configured the Geometry Node Group, you can manipulate individual characters independently. Here are a few examples:

Rotating a Single Character

To rotate a single character, select the character and use the Rotate tool. You can also use the Rotate node in the Geometry Node Group to rotate the character.

Scaling a Single Character

To scale a single character, select the character and use the Scale tool. You can also use the Scale node in the Geometry Node Group to scale the character.

Moving a Single Character

To move a single character, select the character and use the Move tool. You can also use the Move node in the Geometry Node Group to move the character.

Conclusion

In this article, we explored how to separate individual characters from a string to curves in Geometry Nodes. By using a combination of Geometry Nodes and clever tricks, you can manipulate individual characters independently, making it easier to create complex geometry and animations. Whether you're a seasoned Blender user or just starting out, this technique is sure to come in handy.

Tips and Variations

Here are a few tips and variations to help you get the most out of this technique:

Using Multiple Fonts

You can use multiple fonts to create a single string of characters. Simply add multiple String to Curves nodes, each with a different font, and use the Combine node to merge the curves.

Using Different Character Spacing

You can adjust the character spacing by using the Character Spacing node. This node allows you to set the spacing between characters, making it easier to create custom typography.

Using Animation

You can animate individual characters by using the Animation node. This node allows you to set keyframes for individual characters, making it easier to create complex animations.

Using Physics

You can use physics to simulate the movement of individual characters. Simply add a Physics node to the Geometry Node Group and use the Collision node to simulate the movement of the characters.

Conclusion

In conclusion, separating individual characters from a string to curves in Geometry Nodes is a powerful technique that can help you create complex geometry and animations. By using a combination of Geometry Nodes and clever tricks, you can manipulate individual characters independently, making it easier to create custom typography and animations. Whether you're a seasoned Blender user or just starting out, this technique is sure to come in handy.
