Corona SDK plugins
The Dynamic Shader plugin can be used in your Corona project to create 3D shading for your 2D artwork. This shading occurs dynamically in real time, updating every frame, allowing for vivid expressions of mood and atmosphere. The best thing about the Dynamic Shader is its ease of use. It only takes 4 steps and a few lines of code to add dynamic lighting to your app!
