Create custom Garry's Mod sprays and decals. Learn image prep, VTFEdit conversion, VMT file creation, and in-game usage.

Personalize your presence in Garry's Mod by creating custom sprays and decals. These allow you to leave your mark on the game world, whether it's a signature logo, a funny image, or a warning s. This section guides you through the process of making and using your own.

What are Sprays and Decals?

In Garry's Mod, a 'spray' is essentially a custom image that you can project onto surfaces in the game world. It's like painting a tag on a wall. Decals are similar but are often more integrated into the map's geometry or used for specific effects like bullet holes or blood splatters.

Creating Your Custom Spray

The process of creating a spray involves preparing an image file and then converting it into a format Garry's Mod can use.

1. Image Preparation:
  • Choose Your Image: Select an image you want to use. This could be a JPEG, PNG, or BMP file. the image will be projected onto surfaces, so consider how it will look in a 3D environment.
  • Image Editing Software: Use an image editor like Adobe Photoshop, GIMP (free), Paint.NET (free), or even MS Paint for simple images.
  • Transparency (PNG): If your image has transparent areas (like a logo with no background), save it as a PNG file to preserve transparency.
  • Resolution: While Garry's Mod can handle various resolutions, excessively large images can impact performance. Aim for resolutions like 256x256, 512x512, or 1024x1024 pixels.
  • Aspect Ratio: Ensure your image has a reasonable aspect ratio. Stretched or distorted images will look bad when sprayed.
2. Converting to a VTF File:

Garry's Mod uses Valve's Texture Format (`.vtf`) for its textures. You'll need a tool to convert your image into this format.

  • VTFEdit: This is a popular free tool for creating and editing `.vtf` files. Download VTFEdit.
  • Conversion Process: Open your image file in VTFEdit. You can adjust settings like mipmaps (which are lower-resolution versions of the texture used for distant objects) and compression. For sprays, you generally want to keep the default settings unless you have a specific reason to change them. Save the file as a `.vtf`.
3. Creating a VMT File:

A Material Definition File (`.vmt`) tells the game engine how to use the `.vtf` texture. You'll need to create a simple text file with a `.vmt` extension.

  • Create a Text File: Open a plain text editor (like Notepad) and create a new file.
  • Add Material Definition: Paste the following code into the text file:
"UnlitGeneric"
{
 "$basetexture" "your_image_filename"
 "$translucent" "1"
 "$vertexcolor" "1"
 "$orez" "1"
}
  • Replace `your_image_filename` with the exact name of your `.vtf` file (without the `.vtf` extension).
  • Save the file with the same name as your `.vtf` file, but with the `.vmt` extension.
4. Placing the Files:

You need to place your `.vtf` and `.vmt` files in the correct Garry's Mod folder:

  • Navigate to your Garry's Mod installation directory.
  • Go to `garrysmod/materials/vgui/logos/`. If the `vgui` or `logos` folders don't exist, create them.
  • Place your `.vtf` and `.vmt` files inside the `logos` folder.

Using Your Custom Spray in Game

  1. Launch Garry's Mod.
  2. Open the Q menu (`Q` key).
  3. Navigate to the 'Tools' tab and select the 'Spray' tool.
  4. In the spray tool's menu, you should see your custom spray listed. Select it.
  5. Aim at the surface where you want to spray and left-click.

Creating Custom Decals

The process for custom decals is similar but involves placing the `.vtf` and `.vmt` files in the `garrysmod/materials/decals/` folder and then using the 'Decal' tool in the Tool Gun.

Important Notes

  • Server Restrictions: Some servers may disable custom sprays or decals to maintain a consistent visual environment.
  • File Naming: Ensure your `.vtf` and `.vmt` files have identical names.
  • Transparency: For sprays with transparent backgrounds, ensure your `.vmt` file includes `"$translucent" "1"`.

Creating custom sprays and decals is a fun way to add a personal touch to your Garry's Mod experience, making your creations and interactions uniquely yours.
