The following happens when you have mods like Chisel that oredict their block variants:

Could it be possible to make these recipe previews cycle through the oredict variants in just one entry similar to how other recipes cycle through the variants?

The problem is, for these recipes I'm just using a simple Item -> stats array map lookup because its also very efficient (constant time performance rather than O(n) increasing with number of recipes).
So at recipe creation, Oredictionary types are split into individual recipes and the information that they belong to the same Oredictionary ingredient gets lost.

I look what I can do...
