[1.15.2] Why my obj model is hollow?

[grossik]

Hi. I create Blender model, But I don't understand why it's hollow?

And JSON is:

{
	"parent": "forge:block/default",
  	"loader": "forge:obj",
  	"model": "farmcraft:models/block/boiling.obj",
  	"flip-v": true,
  	"transform": { "scale": [0.375, 0.375, 0.375], "translation": [0.4, -0.5, 0.4] } 
}

This problem occurs when they start to change model in modeling tab in blender. And if I add a normal cube without changes so it works.

Hi

Probably - some of your face normals are pointing the wrong way.  Use blender to automatically recalculate them so that your faces are pointing outwards, not inwards.

I try recalculate outside (Mesh -> Normals -> Recalculate outside) but not work. I also tried to recalculate inside and set from faces but nothing worked.

Could you pls put your Blender model and your mod into GitHub?  I will take a look in the next couple of days if you like.

Your base and your top are not quads, they're circles.  You need to tessellate them to quads in Blender
