First double click on Blinking to open the Graph Editor. In the top left corner of the interface you will find all the inputs such as color and speed.
Secondly, go back to the Asset Browser, click on the Public folder then Blinking Scene. We’ll create a cube and apply the custom shader to it.
Create a primitive as the first step. In this case we will use the Cube. Once created, we can apply the shader to the cube.
Click on Assets in the Asset Browser, click on the cube and drag and drop the Shader onto the Components panel. You won’t see the blinking as then you have to Go in your settings in the bottom left and click on Force Redraw. You can then change the speed or color as shown.
