    Hi I am getting this is issue also. The problem i have is i have 100's of shaders and would take hours to try and change and not guaranteed the suggested fixes by users will work. Unity please can you look into this ASAP. Thanks

    Had the same problem in my project. It actually doesn't seem like missing Properties but rather a missing Pass. Anyway, I ended up just switching my Fallback to either Fallback Off or Fallback "Diffuse" which seems fine now.

    I am having the same problem here, with builds that worked on 5.6 no longer working in 2017.1 (iOS build).

    In one of my scripts, I was doing a warmup of a ShaderVariantCollection, to try to manage load time spikes. When I removed this code, the problem still happened. However when I removed the code AND removed the saved .shadervariants file that I was referencing, the build started working again.

    Trying to clear and rebuild the shader variants asset under Graphics did not repair the problem, which came back. However leaving the code back in place did not cause any problem. Therefore the issue seems to be with having the .shadervariant file in the project, for whatever reason.

    Hope that helps some with the bug analysis.

    This is crashing our editor for every assetbundle build we try to make. Never crashed in 5.6 or earlier.

    Likewise happens for us in our project (tested in Unity 2017.1.0f3). Was not a problem in Unity 5.6.1p4 (same project). For us, it happens when we attempt to build our asset bundles (our shader variants are stored in their own bundle).

    Also noticed this in our project. Removed all fallbacks and still the same error.

    The root of this issue is to do with the "Fallback" value in shaders. I am guessing that if a shader does not have the material properties that the Fallback shader requires, it is causing a shader compilation error, as removing the Fallback value from our shaders fixes this issue and allows us to build again.
