[1.12.2] Use #inventory variant for a .obj model

[Darth]

Hi!. I'm use .obj model for block and this works pretty good, but i have so problems with #inventory variant for items. 

 

Spoiler

How i can fix that? That completly ignore all .json files. So please help set that model like standard minecraft block.

 

My .json files:

BlockStates:

Spoiler

{
    "forge_marker": 1,
    "defaults": {
        "model": "tg:teleportator.obj",
        "transform": "forge:default-block"
     },
    "variants": {
        "normal": 
        [
            {
            }
        ],
        "inventory": 
        [
            {
            "transform": 
                {       
                    "gui": { "translation": [0, 2, 0], "scale": 0.125 , "rotation": [{ "x": 300 },{ "z": 45 }] },
                    "firstperson_righthand": { "translation": [0, 2, 0], "scale": 0.125 , "rotation": [{ "x": 300 },{ "z": 45 }] }
                }
            }
        ]
    }
}

 

and models/item:

Spoiler

{
    "parent": "tg:block/teleportator.obj",
     "display":       
     {
         "gui": { "translation": [0, 2, 0], "scale": 0.125 , "rotation": [{ "x": 300 },{ "z": 45 }] },
         "firstperson_righthand": { "translation": [0, 2, 0], "scale": 0.125 , "rotation": [{ "x": 300 },{ "z": 45 }] }
     }
}

Since the model is an obj model you can't scale it down using json(although you might be able to do something with the forge blockstates format since it allows you to specify transforms but I am no expert on that and whether you can specify your own custom transforms).

However the issue here is different. You are trying to use a big model for a 1x1x1 cube. That will not work for a multitude of reasons. One of which you've discovered already - you can't use the same scaled model for an item model.

The other issues would be the collision box, the selection box(none of which work with boxes bigger than 1x1.5x1), the block placement(blocks could be placed into your blockspace occupied by the model) and the frustrum culling(look up from your block and the model will dissappear from sight as soon as the block dissappears from sight(will only work in certain positions of the chunk if I understand MC's chunk rendering correctly as it uses and culls 16x16x16 regions, not individual blocks))

The solution to all those issues would be to scale your model down to a 1x1x1 cube and use a TESR to render it with the scale you need it instead. This solves all but 1(block placement, could be solved with transparent placeholder blocks) issues.

Block placement and collision box i'm already fix with empty placeholder blocks, so thats not a problem.

 

About item model i understand, will try to create another model for item.

The selection box can be as big as you want.

 

JSON models (I don’t know about other models) have a 3x3x3 size limit (at least according to BlockBench - I haven’t tried manually making larger models), so if your block/structure is smaller than 3x3x3 you don’t need a TESR, and can just put a scaling factor into your model’s GUI Transform.

While it can be as big as you want the selection detection only works when you look at the 1x1.5x1 cube and not anywhere else. If you make your selection box a 10x10x10 you will only be able to see it when mousing over the 1x1x1 cube that produces this box. You will see the whole 10x10x10 box though. But this is not the behaviour you want since you want to see the box when you look at it, not the cube producing it.

Sorry yeah, I should have been more specific the size of the selected box that is rendered can be as large as you want, the bounding box that is used determine when that box is rendered is limited to 1x1.5x1 (I assume that box is the collisionBoundingBox or the normal boundingBox).

The solution is to use blocks around it that return the same renderBoundingBox as your block (this may require a TileEntity but only if you use the same type of surrounding blocks for multiple different types of structures)

Also note that AI Pathfinding is similarly not affected by oversized blocks (as I see you already have invisible placeholders, that solves that problem, but it's a thing to be aware of).

This is a blockstate file I was using for a testblock. Note the scale and transform can all be set using a the blockstate file as well as different models for different states if that's what you want. That should be enough for most things. This probably isn't the best example, but it should be enough to get you pointed in the right direction.

Hmm, strange, but thats doesn't work.

Any ideas?
