Summary
When I open a material, a material function, or a material instance and begin moving nodes or clicking inside the editor, the engine lags heavily and suddenly starts compiling between 800–1,200 shaders, in an empty project with a normal-sized material that isn’t particularly complex.
This happens even if I’m only editing inside the Material Editor without applying any changes. Each time I try to add new nodes or adjust something, the engine immediately reloads shaders.
As a result, this constant recompilation not only slows down my workflow but also sometimes causes the engine to crash, resulting in lost progress.
