SubscribeDownload Open Source Starter ProjectIn order to pass uniforms to both the vertex and fragment shader functions in Three JS, you must:
- Add the uniform struct to the shader material.
- Create uniform variables that match the keys that you set in the uniform struct of the shader material in both the vertex and fragment shader.
- Access the uniforms in either the vertex or the fragment function.
An example of this can be seen in the tutorial linked below that discusses how to add a light to a shader material in Three JS.
