Item model issue

I recently Installed SpiderFrog's Old Animations Mod and have noticed that the 2D item feature present In the mod has shading unlike vanilla 1.7 2D items. This Is not a problem with the mod rather that Minecraft renders item entities like this post 1.8. It can be easily removed by putting this In a item json file ("shade": false,). I have no clue for where to or how to put It in a json folder. Where should I put "shade": false, In the item model? Help would be appreciated!
