Fixed in 1.31

This has now been fixed in 1.31

It appears to only for textures (https://docs.unity3d.com/Manual/SL-Properties.html), which SF already supports. Do correct me if I'm wrong though!

In case you just need it for textures, you can right-click on texture assets and texture 2D nodes to tag them with PerRendererData

Of course it's better to have it fixed than not, I'm just saying that it's not an easy fix on my end. Your best bet for now is to reduce the amount of interpolators needed by removing features such as fog, if possible

It can be fixed, but it's not an easy one, because combining multiple Vector2 interpolators into a single Vector4 is very expensive on some platforms, which is why I can't simply just implement it as-is

This has now been fixed in SF 1.31

I'll prioritize this for the next update!

5.5.0f3 is the one I was testing it in, which appeared to work just fine

Somehow I can't reproduce this. Are you using Unity 5.5.0f3 and Shader Forge 1.3?

This has now been fixed in 1.30, which will release in a few minutes
