Buggy 3D Doors

[camgix]

I am trying to add sphax's new 3d doors to a personal resourcepack, but the doors are very buggy and i cant fix them. When i am within a block of the top of the door, it returns to normal. but when i am away from it, it shows the top half as a missing texture. It isn't my computer either, i have had no problems until now. I double checked that i had moved all the model .json files, when i attempted to create a "blockstates" folder and add the blocks that i needed, the games textures went into plain coloured blocks.

You just forgot some json files that the above door part requires
Read the json door to know which one(s).
