You might be using this shader incorrectly.
First, let me explain that the shader’s behavior simply declares the shader, while the shader is applied to a node through an action.
For example, create a scene with cubeMesh1 and four light sources.
After add PSX Shader to behavior of the root node, add the lighting nodes, and enable the UseLight.
And after that, call PSX Shader action to assign the shader to cubeMesh1. I trigger the shader assignment in the "Before first drawing do something" event.
