I have this texturepack that creats alternative textures and models for mc vanilla.

In 1.14 it worked just fine, however, in 1.15 it will not regonize it as working properly.

The .json file called 0_composter is the file that is supposed to go into the blockstates, plz note that i have added the '0_' only to disable it for the moment and i have the following files in a folder called 'Comp' in the models > block folder, so there is nothing wrong there.
