Please see attached zip file that contains the 4 shaders.
NONE of the shaders have anything to do with each other. We just in building/re-building the project apparantly messed something up bad somewhere. No matter what we do now we are constantly faced with errors for these shaders ranging from: "Sampler4D is not defined" to "XYZ is a replication" etc. etc.
The job is simple and should take no time to complete. Unfortunately nobody on this team has ever even touched a shader in their life so we basically need someone to come in and make sure they are working again.
Need these debugged and fixed ASAP will pay very well for this if you do job immediately on the spot of being awarded right now.
P.S: As a tip to help you get started, we noticed that a couple of files have the shader in it multiple times. No idea how this happened and really don't care to find out we just need them working again.
