I hope somebody else can pitch in here. I jumped into it a while a go but then abandoned it. The library of layer blends seemed like the way to go. But it was frustrating because there seemed to be no way to measure the performance… In the epic videos they say that it only compiles the necessary nodes in the final material but in the shader stats it jumps up really high to like 16 Texture Samples/Lookups with just one lightweight layer. And in the shader optimization viewmode it seems to just display the same dark green color regardless of complexity. To me it just ended up being faster to just alter an existing material and use instances than to try and do everything with a bunch of premade bend nodes. If you make a bunch of nodes at the beginning of a production you are kind of locked into that bc if you want to alter anything it will change all the already existing materials and it just got really confusing
