So I thought I’d see what all the fuss was about and downloaded RyanB’s ShaderBits Octahedral Imposters plugin, and uh… well:

Let’s just say it doesn’t work at all. is there something I’m missing, or did i break it somehow, or is it just broken to begin with? I followed the steps to the letter and haven’t changed anything about the plugin, so I’m not sure what’s going on
The “Full Sphere” version looked like this for me, until I enabled the MIC switch for FullSphere_3.
uwu ok! what’s a MIC switch FullSphere_3 though 
In case anyone else comes looking for why your full sphere impostors are broken, it is because there is a broken static bool parameter inside the Imposter_ThreeFrameBlend material function - one of the “Full Sphere” params is incorrectly named “Full Sphere_3” so the impostor baker blueprint can’t find it when you change to using a full sphere.
If you remove the _3 from that param and save, it will work again.
Hi, I’m on 5.3 here and the full sphere impostors still don’t work, despite a change in the shader.
The fix shown above does not longer apply.
With a bit of inspection I found out that the material created with the “full sphere view” option still has the “UpperHemisphereOnlyImpostor” checked. Seemed like an error, so I unticked it, and it gave much better results.
However, there are still issues while looking from under the asset : at low angles, some artifacts will appear on top of the impostor, and when looking from directly under it the result is a mess.
Horizontal view:
Low angle view:
Vertical view from right under it:
I don’t know if anyone else bumped into this issue, but I thought it could be useful to revive this topic.
