[SOLVED] [1.18.2] How to set a different inventory texture for an Item Entity model

[JimiIT92]

I have an Item that is also associated with an entity, and so the entity model is rendered in inventory. However how can I make so in Inventory a plain texture is rendered?
This is what I tried so far: the JSON file for the Item is the following
 

{
  "parent": "minecraft:builtin/entity",
  "gui_light": "front",
  "textures": {
    "particle": "blazersmod:item/spear"
  },
  "display": {
    "thirdperson_righthand": {
      "rotation": [ 0, 60, 0 ],
      "translation": [ 11, 17, -2 ],
      "scale": [ 1, 1, 1 ]
    },
    "thirdperson_lefthand": {
      "rotation": [ 0, 60, 0 ],
      "translation": [ 3, 17, 12 ],
      "scale": [ 1, 1, 1 ]
    },
    "firstperson_righthand": {
      "rotation": [ 0, -90, 25 ],
      "translation": [ -3, 17, 1],
      "scale": [ 1, 1, 1 ]
    },
    "firstperson_lefthand": {
      "rotation": [ 0, 90, -25 ],
      "translation": [ 13, 17, 1],
      "scale": [ 1, 1, 1 ]
    },
    "fixed": {
      "rotation": [ 0, 180, 0 ],
      "translation": [ -2, 4, -5],
      "scale":[ 0.5, 0.5, 0.5]
    },
    "ground": {
      "rotation": [ 0, 0, 0 ],
      "translation": [ 4, 4, 2],
      "scale":[ 0.25, 0.25, 0.25]
    },
    "gui": {
      "rotation": [ 15, -25, -5 ],
      "translation": [ 2, 3, 0 ],
      "scale": [ 0.65, 0.65, 0.65 ]
    }
  },
  "overrides": [
    {
      "predicate": {
        "throwing": 1
      },
      "model": "blazersmod:item/spear_throwing"
    }
  ]
}

And in the Item class I override the initializeClient method to return my custom ItemRenderer instance

@Override
    public void initializeClient(Consumer<IItemRenderProperties> consumer) {
        consumer.accept(new IItemRenderProperties() {
            @Override
            public BlockEntityWithoutLevelRenderer getItemStackRenderer() {
                return BlazersMod.getItemsRenderer();
            }
        });
    }

for which, in the renderByItem method, I do this
 

@Override
    public void renderByItem(ItemStack stack, ItemTransforms.@NotNull TransformType transformType, @NotNull PoseStack pose, @NotNull MultiBufferSource buffer, int packedLight, int packedOverlay) {
        if(stack.getItem() instanceof SpearItem) {
            pose.pushPose();
            pose.scale(1.0F, -1.0F, -1.0F);
            EntityModel<ThrownSpear> model = this.spearModel;
            ResourceLocation layerLocation = ThrownSpearRenderer.SPEAR_LOCATION;
            VertexConsumer vertexConsumer = ItemRenderer.getFoilBufferDirect(buffer, model.renderType(layerLocation), false, stack.hasFoil());
            model.renderToBuffer(pose, vertexConsumer, packedLight, packedOverlay, 1.0F, 1.0F, 1.0F, 1.0F);
            pose.popPose();
        }
    }

What should I specify to render not the model but a plain texture in Inventory? Or where can I look at? I tried looking at the Trident but can't find anything related

Thank you For reference if anyone has the same issue, this is what the JSON file now looks like
 

{
  "loader": "forge:separate-perspective",
  "base": {
    "parent": "blazersmod:item/spear_in_hand"
  },
  "perspectives": {
    "gui": {
      "parent": "blazersmod:item/spear_inventory"
    },
    "fixed": {
      "parent": "blazersmod:item/spear_inventory"
    },
    "ground": {
      "parent": "blazersmod:item/spear_inventory"
    }
  }
}

You don't need to specify the whole model inside, you can just reference an existing JSON file as "parent" for the given perspective (for instance, here I've set the "in_hand" model as my base model and the "inventory" model for when the Item is in Inventory, dropped on the ground or inside an Item Frame
