A General Problem

Hi 
I Updated Shader Forge to 0.35 Beta
I have two problem ... They're not bug ... so I selected Ideas

- First problem :
Why Shader Forge shaders are two heavy ?
for example i want just one lerp material that blend 2 texture together
Compiled code is 19 000 Line Code !
Is not it very heavy for a simple shader ?

Simple lerp with code :


And Simple Lerp with SF:


I want to know it can make game performance down ?

And second problem :

Shader Forge 0.35 "open source" button not working !
