Recompiling all Shaders too often


I have this really annoying “bug”, where I have to recompile all ~6000 shaders quite often, including the stop at 45% when opening the project. My private PC is quite old and not that powerful, so, this is really really annoying.

What I did: I recently started a new project and tested a few sample projects and a few oculus samples. So, I did open many projects. I guess, that there is some sort of intern maximum of how many projects can have compiled shaders and that I reached that threshold and some project shader caches were deleted, atleast that’s my best explanation for my problem.

I would like to increase that maximum if it exists but I’m also open to any other solution. Developing with Unreal is already pretty time consuming if everything works fine, but this makes it nearly impossible to get anything done.
