Block side turns black if side faces solid block

[LordFetzi]

Hey just as written in the title my custom block side turns black if a solid block is facing that side.
I have already tried everything concerning the blockmodel.json.
I have set the ambientocclusion to false, shade to false and render_type also to cutout, but nothing seems to work.

If anything else is needed to help me with my problem don't bother to ask me for more information.

The blockmodel ingame:

Here is the blockmodel.json file:

I don't know about the model you are using, but for the vanilla models this is function of the shapes defined in your block class (not just the model).

If you have a full face in your shapes it will stop light entering the block to internal faces.

 

Here's a thread where I try to explain it from my limited understanding. I am far from an expert on minecraft's lighting code. 🙂
