 [Post Processing - Custom Render Pass](../examples/shader/custom_post_processing.rs) | A custom post processing effect, using a custom render pass that runs after the main pass
 [Shader Defs](../examples/shader/shader_defs.rs) | A shader that uses "shaders defs" (a bevy tool to selectively toggle parts of a shader)
 [Specialized Mesh Pipeline](../examples/shader/specialized_mesh_pipeline.rs) | Demonstrates how to write a specialized mesh pipeline
+[Stochastic Sampling](../examples/shader/stochastic_sampling.rs) | A custom shader that avoids repetition artifacts when tiling a texture
 [Storage Buffer](../examples/shader/storage_buffer.rs) | A shader that shows how to bind a storage buffer using a custom material.
