Why are shaders compiling every time I open a map.
We figured out the issue.
So we had a ton of road splines in the map using the same material as everything else. However, we didn't check "Used With Spline Meshes" in the material. So unreal was auto-checking that on in the background every time we opened the map causing all of the shaders to recompile over the already compiled shader cache from before. Once we checked on ""Used With Spline Meshes" in the material, the problem was fixed.
So.. it would be nice if there was a visual warning that popped up saying that it auto checked it for us, or if it made changes to the material directly and just needed us to save the material. But idk. Regardless, it was a huge headache for something so simple.
