Specifically, sometimes it gives items random textures, doesn't give the item the proper model (noticeable when the item is held in hand or dropped in ground) and sometimes it just doesn't give some items models or textures.

Currently all getTextureName can do is get the damage. Would be nice to also be able to get the stack.

The method can be replaced with "return IPerspectiveAwareModel.MapWrapper.handlePerspective(this, transforms, cameraTransformType);" as shown here: https://github.com/SlimeKnights/TinkersConstruct/blob/129dbbe84db272a131f962442d58dadd72ff786b/src/main/java/slimeknights/tconstruct/library/client/model/BakedMaterialModel.java#L68

This may fix TechReborn/RebornCore#12 but I'm not certain.

this crash happens during startup, there is no standalone jsondestroyer in my mods folder, so this cant be the case

additionally i have this: Tesla{1.0.1.9} TESLA installed

still crashing with reborncore{2.1.0.61} RebornCore

Basically like ITexturedItem but instead of retuning a single texture you would return an array of textures, and they would be layered in order on top of eachother.
