No, it’s not practical.

Eevee Shader Compilation

Hi guys, I’ve been wondering if Cycles and Eevee optimize shaders with NodeGroups in mind. So if there is a NodeGroup used in tens of materials, is it compiled once and then reused or does it compile by ungrouping and then compiling with the rest of the material being compiled at that point. I know that in Cycles updating shaders takes an instant but in Eevee it looks this is somewhat slower. Could be because Eevee shaders are computationally harder or do they always need to recompile comple…
