Avoiding extraneous point lights in Vertex Lit shaders?

Hello.

In my game I'm using the Vertex Lit rendering path on mobile platforms, and my scenes are lit by one point light. I'm targeting ES 2.0+ hardware. I noticed when using the Xcode frame capture feature that the vertex shaders that are generated for this path support four point lights. I only need one so that seems like a waste of GPU. Is there a way of inducing ShaderLab to support fewer point lights in the Vertex Lit path?

 

If you switch to the Forward Rendering Path and use the options novertexlights and noforwardadd, and implement your own vertex lighting in the vertex shader you might get what you want.

That being said, if you really want to get best performance on OpenGL ES 2.x hardware, you probably should write a GLSL shader and optimize it.

 

Ah, I did try the Forward path with lots of options to simplify the shaders but didn't consider actually just writing my own shader. I think that might be the best solution. Thanks for the tip.
