Hey! I had the same problem with the 4.1 version of the engine. It got solved, now we have the 4.2 version and it’s back again. I am just sitting here, playing with the material editor tools and the engine compiles thousands of shaders… Old Thread: [image] Shaders compile after every mate…

Okay, I think I solved the problem for me. At the moment it works, I had to deactivate the real time protection of GData for the engine. I guess while it’s compiling shaders the engine changes a lot of files, which causes GData to slow everything down.

Shaders compile after nearly every material alteration
