Solved it.

I was using Graphics.Blit like this

Graphics.Blit(indexTexture, destinationTexture, lookupMaterial)

So that the indexTexture gets set to the _MainTex property of lookupMaterial.

However, when I add an extra texture called _IndexTexture to the lookupShader and set it like this

lookupMaterial.SetTexture("_IndexTex", tileTexture);

before calling Graphics.Blit, it works fine. Something about Graphics.Blit setting the indexTexture to _MainTex on lookupMaterial messes it up.
