I have been playing with custom frames, specially in a way to functionally break my code up into reusable parts. Bludy brilliant feature so by the way. Here is a example > **[Babylon.js Node Material Editor](https://nodematerial-editor.babylonjs.com/#EK342L%231)** > > Babylon.js Node material editor - shader-based materials editor for Babylon.js In this example I have three circles, each being a custom frame. Would it not make sense to treat custom frames as functions when generating the shader? This would clean up the generated code rather nicely. Or, is there a performance hit with functions? I saw that in one of the shader videos the presenter was talking about if statements having some performance issues and so using step as a if statement would perform better. Is functions also problematic or can one treat custom frames like functions? ---

Nope functions are fine. We are not trying to have a clear output to be honest. the shader is not meant to be read (not the primary goal of NME ) But I totally get your point still 🙂
