When I go to package my project for windows, it critically fails and gives me this error (below). I really need help because the project is due soon and I am lost. I think it has something to do with forward shading.

You have several warnings:
Warning: (): shader uses 17 samplers exceeding the limit of 16. Start by fixing your shaders that use too many samplers.

3

Where do I change the number of samples in my shaders? I’m not to familiar with the technical side of Ue4 so I’m not sure what your referencing

4

The number of samples is set by the platform you are cooking for. You need to change your materials to fit inside that limit.

5

I went through all my materials and couldn’t find any that are over the sampler limit.

6

I migrated the level to a new project using unreal vr template and then it worked.
