Yes, it's an interesting case. Shader Model 3.0, should work on most devices but do keep in mind that it may not be fully supported by some OpenGL devices, depending on driver extensions present and features used. Awesome, thanks! Looking forward to those assets! It should work, Impostors can work individually, just as regular models. That's an odd one but, unfortunately, we're unable to support beta Unity versions. In any case, I'm not entirely sure if the issue is strictly caused by your sprecific Unity version(2018.1.0b13), we could really use some additional information. Is the problem present on a new empty project using that specific version? Does it work on your side using Unity 2017 or 2018 release versions? Are you using the latest Amplify Impostors version, 0.8.2? Average PBR material memory use; Depth excluded, you can actually select which channels to include; 1 texture per-channel(Albedo, Normal, etc) containing a set of views. Impostors use Alpha Cutout.
