If you are going to have animation use a FastTESR and not a normal TESR. It actually does most of that code for you and it is more efficient. You to @_Cruelar_

Check out the docs.

Thanks!

Yea...I make all as toturial  "OBJ without animation", but i think there is a problem with blokstate .json file. I copied it from link, changed modid to my, and to my obj model name, but i have this error in eclipse log:

https://pastebin.com/QRZmnSsk

 

 

This is my blockstate json, where i defited the location of OBJ model

{
  "forge_marker": 1,
  "defaults": {
    "custom": { "flip-v": true },
    "model": "modtut: model.obj"
  },
  "variants": {
    "normal": [{}],
    "inventory": [{}]
  }
}

 

 

I don't know, why the "model.obj" it understand as "model.obj.json"..

[Musicgun47]

It looks like you haven't properly instantiated the OBJLoader. If you had, the loader should have a line like this:

[main/INFO] [FML/mod_id]: OBJLoader: Domain mod_id has been added.

before it attempts to load the model.

Make sure you've included the 

OBJLoader.INSTANCE.addDomain(MODID);

line in the preinitialization stage.

I have got this

*Bump*

 

I had now this error  

https://pastebin.com/amFm81vy

 

I hate it...

 

[Draco18s]

Caused by: java.lang.RuntimeException: OBJLoader.Parser: Exception parsing line #104: `vt -0.087167 -0.000000`

 

IIRC the Minecraft OBJ loader does not take texture UV coordinates.

[Musicgun47]

This is a problem with your UV mapping for your model. Minecraft does not support UV mappings outside of the 0-1 range. This means all of your mappings need to be inside this range for the model to be loaded.

 

If you're using Sketchup, All the mapping should be within the non-greyed out area of the UV editor.

[MrPablo2000]

I make all as your solution, but it stil isn't working..

Eclipse log:

ModelORO.obj:

https://pastebin.com/wTTej896

 

 

modeloro.mtl

https://pastebin.com/Gf7twXN8

 

 

Texture modeloro.png is in the same folder as modeloro.mtl and modeloro.png

Caused by: java.lang.RuntimeException: OBJLoader.Parser: Exception parsing line #70: `vt -1.42413e-16 0.845956`

You still have uv coordinates issues. The uvs must be in range [0-1]. -1.42413e-16 isn't.

[MrPablo2000]

Thanks - now ist rendering on placed - but the model is too big ?

You will need to scale it down in your modeling program nothing bigger than a block.

[Musicgun47]

That's just a scaling issue. Fixing it it mostly just trial and error until you get it to the size you want.

 

You can either fix it in the blockstate JSON which is tedious as you'd have to include the scaling for all variations, or, the easier way, scale it down in your 3D modelling program until it's the right size in game.

[MrPablo2000]

How is the size of normal block in minecraft ? For how size I must scale down my model ?

1 meter. But I think all you have to do is make the object 1 whatever-unit-your-modeling-program-uses so that the output OBJ file has all of the coordinates in the [0-1] range as well.

[MrPablo2000]

I deleted "-" and changed it, that all coordinates are in 0-1 range. But is still too big. What I can do ?

Can you post the whole model file?

 

Also, "1.42413e-16" can be changed to "0" just fine.

These coordinates are not 0-1. You haven't scaled your model.

It's a little hard to help when we can't see the code, and if it is a red line underneath the code listen to eclipse for the error and solve it.
