Atlas Tile Wrapper

Atlas Tile Wrapper

The Atlas Tile Wrapper is a specialized utility designed to enable seamless texture repetition for individual tiles within an atlas. Much like the functionality of trim sheets, it allows you to repeat sub-textures in both directions while maintaining the efficiency of a single texture sheet.

Benefits

• Performance Optimization: Significantly reduces draw calls by batching multiple objects into a single material.
• Enhanced Resolution: Achieve higher visual fidelity using smaller source textures through tiled repetition.
• Workflow Efficiency: Streamlines material management and accelerates the baking process for complex assets.

Workflow for Blender

1. Material Setup: Create a new material and import your Atlas Textures, ensuring the interpolation is set to Closest.
2. Node Integration: Add the Atlas Tile Mapper NodeTree to your shader graph.
3. Parameter Configuration:
   • Repeat: Set the frequency of the texture repetition.
   • Tile Count: Define the grid size of the atlas.
4. Mapping: Connect the node output to the UV Vector input of your textures.
5. UV Projection: Project the UVs of your model to the specific tile area. For best results, use Cube Mapping.
   • Note: You can further fine-tune repetition density by scaling the UV islands directly in the UV editor.

Workflow for Godot

1. Texture Import: Bring your Atlas Textures into the project. If you encounter visual artifacts, disable Filter and Mipmapping in the import settings.
2. Shader Application: Create a new ShaderMaterial and apply the Atlas Tile Wrapper shader.
3. Adjust Settings:
   • Tile Count: Define the grid size of the atlas.
   • Scale: Control the number of texture repetitions.
   • Material Inputs: Assign your Atlas maps to the corresponding slots (Albedo, Specular, Metallic, Roughness, Emission, Normal, and AO).
   • Surface Details: Fine-tune Emission Energy, Normal Scale, and AO Light Affect.
4. Secondary Mapping: Use the Texture AO UV2 toggle if you are utilizing a secondary UV channel for baked ambient occlusion.
