it doesn’t work at all. I 've set Priority to Low for Unreal Engine, and the Shader Compiler to High and even created a material instance. It takes 20 secs to compile shaders each time. I am trying to change a refraction value and this is making it impossible to work with. Why is everything with UE so ■■■■ complicated? There are so many people talking about this issue on so many different threads and there is no solution… I have worked with Unity, Sketchfab, Marmoset, 3DCoat and none of them had this issue. I even had to research how to import a model from 3dsmax to Unreal for god’s sake because apparently you have to be working in meters inside 3dsmax but export in cm!!! Everything about this engine is so counter intuitive!
