The most recent update for the shader should address this. If you grab it and it still doesn't work, let me know and I'll go through it again.
I have a bad habit from other languages and engines of passing interger values when it explicitly needs a float value. Make sure if you made any changes to the transforms or shaders that any numbers, even if they're ordinarily whole numbers, are expressed as floats. E.g 1 should be 1.0, etc.
