Shader analysis
- [Instructor] Another great lens to look at your project through is Shader Complexity. Generally speaking, it's a good indicator of your project's performance, since shader rendering comprises a large component of the rendering pipeline. But it's not always clear what to do with this info, so that's what I'll try to address here. Let's begin by enabling the Shader Complexity view mode. You can find it in View Modes, Optimization View Modes, and Shader Complexity, or the shortcut is alt eight. What this mode does is colorize every pixel based on the number of instructions the material graph's drawing in. We can even use the reticle to sample the shader complexity in specific areas. For example, when I aim it here, you can see that we're hitting this area that's somewhere between bad and extremely bad. Not to worry, most projects can handle quite a bit of shader complexity, even as high as the white. But as long as the majority of your scene is somewhere between good and bad, I think…
