Block texture showing up in inventory, but not when placed.

[Mxdyvz]

Hi, before starting, i'd like to state that this is not a problem of forge, but still i wanted to ask help here since i've got no results yet from other sources.
I've recently made a custom model on blockbench of a block/item, i got everything correct in the resource pack folder (it's just a texture/model, no mods or anything else is required when using it), i get in the game and rename the item to the name that would turn it into the custom textured item.
When having it in the inventory/hotbar, the texture does display, but when placing it it does not.
Any help please?

EDIT: i don't need to use or interact with the item, i just need to display it like a hologram/title

You might need to have a custom model for the block too.
