Cannot seem to set position of bone, only position of geometry | Blockbench | Page 1

Hi! I'm trying to take a 1.18.2 LivingEntity and backport it to 1.16. I've got the deobfuscated java file and I'm using that to try to reconstruct the model in block bench. However, there's a method, PartPose.offsetAndRotation, that doesn't seem to have a BlockBench analogue.

Here is the code for the first two bones:

            CubeListBuilder.create()
                .texOffs(0, 30).addBox(-3.0F, -1.5F, -1.5F, 6.0F, 3.0F, 3.0F)
                .texOffs(64, 19).addBox(-3.5F, -2.0F, -2.0F, 7.0F, 4.0F, 4.0F), 
            PartPose.offsetAndRotation(0.0F, -13.5F, 0.0F, 0.3927F, 0.0F, 0.0F));

        PartDefinition bodymiddle = bodybottom.addOrReplaceChild("bodymiddle", 
            CubeListBuilder.create()
                .texOffs(0, 25).addBox(-2.0F, -2.5F, -1.5F, 4.0F, 3.0F, 2.0F)
                .texOffs(0, 25).addBox(-0.5F, -2.0F, -1.6F, 1.0F, 2.0F, 0.0F),
            PartPose.offsetAndRotation(0.0F, -1.5F, 0.5F, -0.1745F, 0.0F, 0.0F));```

Pictured below is what I have so far.

Now, the `PartPose.offsetAndRotation` seems to be setting a position for the bone itself, and the first three arguments of the `addBox` command seems to be placing the geometry's position _relative_ to the bone. The problem is that I don't seem to be able to place the bone's position in the editor. (See red question marks where position normally is.)

How do I handle this? Is the intended flow to add the cube's translation to the bone's translation, then set the bone's "pivot point" to be the offset? If I do that, then export to an MCP java file, will it subtract the bone's translation from the geometry's translation automatically?

Have you considered asking the mods author whether you're allowed to use their model?

#

They could give it to if they're fine with it.

The mod author said that he'd do a 1.16 backport, but he didn't want to convert the models, so I offered to do it for him. Problem is that Blockbencch can't import 1.18 java files, hence why I thought I'd try to do it by hand.

#

I was eventually able to figure it out. Once I'd done one by hand, and thus knew the process thoroughly, I was able to automate it, and now I've got a script now that will convert 1.18 models into 1.16 format. Ironically, these 1.16 java files can then be loaded by blockbench, so in a roundabout way I've gotten blockbench to accept 1.18 models.

Welp, then at least make sure that the mod author learns to keep the bbmodel, and stops ignoring the massive warning it gives you on export.
